    Station Bönered: om att skapa goda miljöer kring ett pendeltågspår2008Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [sv]

    När en stad växer måste man ta ställning till hur det ska ske. Idag är biltrafiken dominerande i Göteborg och i framtiden skulle spårbunden trafik och utbyggd pendeltågstrafik i regionen kunna innebära mer hållbara tranporter. En pendeltågsstation har ett relativt begränsat omland och behöver för fullt utnyttjande bebyggas nära inpå. Den spårbundna trafiken kan dock innebära störningar och risker. Jag undersöker i mitt examensarbete hur en ny stadsdel utanför Göteborg kan byggas ut kring en tänkt pendel­tågs­station. För att göra detta under­söker jag bl a järnvägen som kommunikations­medel och som störningskälla. Spåret är tänkt att gå mitt i sam­hället och barriär­effekten som kan uppstå mot­verkar jag genom att lyfta upp järnvägen på en brokonstruktion. Stadens struktur kan således fortgå under spåret utan avbrott. Bullerstörning och olycksrisk går att åtgärda och förebygga med olika för­ stärkningar i fasader vilket gör att byggnader kan ligga nära spåret och skydda bakomliggande kvarter. Eftersom samhället planeras på obebyggd mark undersöker jag även hur man kan ge förutsättningar för en god blandad stad. Jag undersöker vad som gäller för strukturen, bebyggelsen, funktion­erna och de offentliga rummen. Slutligen applicerar jag allt detta på ett planförslag där jag går in mer i detalj på kvarteren närmast spåret.

    Clustered Shading: Assigning arbitrarily shaped convex light volumes using conservative rasterization2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Context. In this thesis, a GPU-based light culling technique performed with conservative rasterization is presented. Accurate lighting calculations are expensive in real-time applications and the number of lights used in a typical virtual scene increases as real-time applications become more advanced. Performing light culling prior to shading a scene has in recent years become a vital part of any high-end rendering pipeline. Existing light culling techniques suffer from a variety of problems which clustered shading tries to address.

    Objectives. The main goal of this thesis is to explore the use of the rasterizer to efficiently assign convex light shapes to clusters. Being able to accurately represent and assign light volumes to clusters is a key objective in this thesis.

    Methods. This method is designed for real-time applications that use large amounts of dynamic and arbitrarily shaped convex lights. By using using conservative rasterization to assign convex light volumes to a 3D cluster structure, a more suitable light volume approximation can be used. This thesis implements a novel light culling technique in DirectX 12 by taking advantage of the hardware conservative rasterization provided by the latest consumer grade Nvidia GPUs. Experiments are conducted to prove the efficiency of the implementation and comparisons with AMD´s Forward+ tiled light culling are provided to relate the implementation to existing techniques.

    Results. The results from analyzing the algorithm shows that most problems with existing light culling techniques are addressed and the light assignment is of high quality and allows for easy integration of new convex light types. Assigning the lights and shading the CryTek Sponza scene with 2000 point lights and 2000 spot lights takes 2.92ms on a GTX970.

    Conclusions. The conclusion shows that the main goal of the thesis has been reached to the extent that all existing problems with current light culling techniques have been solved, at the cost of using more memory. The technique is novel and a lot of future work is outlined and would benefit the validity of the implementation if further researched.

    Electric Vehicle Charging Station Markets: An analysis of the competitive situation2012Student thesis
    Abstract [en]

    Electric Vehicles represent a small niche market today, but is predicted to grow rapidly over the next years. In order to prepare for this upcoming trend it is the networks of Electric Vehicle Charging Stations (EVCS) must expand, leading to an increasing demand for EVCSs. The EVCS market is thus becoming increasingly more popular to companies, and therefore this study’s purpose is to investigate this market and its competitive situation. The method used in this study includes a brief market analysis and a competitor analysis. The market analysis includes identification of the EVCS markets together assessing the future of the markets, and identification of EVCS market drivers and restraints. The competitor analysis includes competitor identification, classification and analysis. The top ten competitors are analyzed by the use of document content analysis, the analysis involves understanding the competitors’ target customers, how they do business and how their marketing material is structured. The three most promising EVCS markets, both currently and in the future, are the Asia Pacific, Europe and the North America markets. Most of the top competitors are active within these three markets. Regional developments, and market drivers and restraints of these markets have been identified. The opportunities in the EVCS markets are many as they are relatively unexploited markets without any actual market leaders, and also that all markets are predicted to grow at a very high rate over the coming decade in parallel with the projected mass adoption if Electric Vehicles (EVs).

    Att tygla Diabetes typ 2: Upplevelser av att göra livsstilsförändrningar2014Student thesis
    Abstract [sv]

    Bakgrund: Diabetes mellitus typ 2, som är ett globalt växande problem, är en metabolisk sjukdom, som till följd av problem med eller avsaknad av insulinproduktion eller insulinkänslighet kan leda till allvarliga komplikationer. Grunden för all behandling av diabetes typ 2 är goda levnadsvanor i form av fysisk aktivet och lämplig kost. Egenvården kan behöva stöd av hälso- och sjukvården, vilket förutsätter kunskap hos sjuksköterskor. Syfte: Syftet med studien var att belysa upplevelser av livsstilsförändringar efter det första året hos personer med diabetes typ 2. Metod: Metoden som användes var en litteraturstudie med kvalitativ ansats. Analysen gjordes utifrån Graneheim och Lundmans tolkning av en innehållsanalys. Resultat: Livsstilsförändringarna upplevdes innebära förändringar i vardagen, främst gällande matvanor och motion, och känslomässiga förändringar såsom rädsla för sjukdomen och saknad av livsstil. Personerna blev påverkade av omgivningen, såväl familj som arbetsplats. Livsstilsförändringarna krävde anpassning till sjukdomen där insikt om vad sjukdomen kräver var viktig och där kontroll av livsstilsförändringar ledde till framtidstro. Slutsats: Den globala sjukdomen diabetes typ 2 kan förbättras genom en förändrad livsstil. Upplevelser av att göra livsstilsförändringar kan variera mellan positiva och negativa. Att genomföra livsstilsförändringar kan både upplevas motiverande såväl som innebära en utmaning. Med hjälp av stöd från hälso- och sjukvården ska personer med diabetes typ 2 förses med verktyg att klara sin egenvård.

    On Radio Wave Propagation Measurements and Modelling for Cellular Mobile Radio Networks2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    To support the continuously increasing number of mobile telephone users around the world, mobile communication systems have become more advanced and sophisticated in their designs. As a result of the great success with the second generation mobile radio networks, deployment of the third and development of fourth generations, the demand for higher data rates to support available services, such as internet connection, video telephony and personal navigation systems, is ever growing. To be able to meet the requirements regarding bandwidth and number of users, enhancements of existing systems and introductions of conceptually new technologies and techniques have been researched and developed. Although new proposed technologies in theory provide increased network capacity, the backbone of a successful roll-out of a mobile telephone system is inevitably the planning of the network’s cellular structure. Hence, the fundamental aspect to a reliable cellular planning is the knowledge about the physical radio channel for wide sets of different propagation scenarios. Therefore, to study radio wave propagation in typical Australian environments, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Telecommunications Cooperative Research Centre (ATcrc) in collaboration developed a cellular code division multiple access (CDMA) pilot scanner. The pilot scanner measurement equipment enables for radio wave propagation measurements in available commercial CDMA mobile radio networks, which in Australia are usually deployed for extensive rural areas. Over time, the collected measurement data has been used to characterise many different types of mobile radio environments and some of the results are presented in this thesis. The thesis is divided into an introduction section and four parts based on peer-reviewed international research publications. The introduction section presents the reader with some relevant background on channel and propagation modelling. Also, the CDMA scanner measurement system that was developed in parallel with the research results founding this thesis is presented. The first part presents work on the evaluation and development of the different revisions of the Recommendation ITU-R P.1546 point-to-area radio wave propagation prediction model. In particular, the modified application of the terrain clearance angle (TCA) and the calculation method of the effective antenna height are scrutinized. In the second part, the correlation between the smallscale fading characteristics, described by the Ricean K-factor, and the vegetation density in the vicinity of the mobile receiving antenna is investigated. The third part presents an artificial neural network (ANN) based technique incorporated to predict path loss in rural macrocell environments. Obtained results, such as prediction accuracy and training time, are presented for different sized ANNs and different training approaches. Finally, the fourth part proposes an extension of the path loss ANN enabling the model to also predict small-scale fading characteristics.

    Comparisons and Evaluation of ITU-R Recomendation P.1546 Versions2006Conference paper (Refereed)
    Abstract [en]

    In this paper, the validity of P.1546, in short range (typically less than 20km) terrestrial environment is analysed by comparing its three versions (P.1546, P.1546-1, and P.1546-2) against simple models and against measurement results obtained by utilising the pilot signal of a commercial CDMA mobile network in rural Australia. The results show that the latest version on average underestimates the field strength by more than 10 dB for typical Australian rural areas, however it improves the error standard deviation. The causes of these effects and the suggestions for further development of the Recommendation are discussed.

    Evaluation of a New Effective Antenna Height Definition in ITU-R Recommendation P.1546-12005Conference paper (Refereed)
    Abstract [en]

    The International Telecommunication Union has recently developed a new Recommendation on the method of point-to-area predictions for terrestrial services in the frequency range 30MHz to 3000 MHz. It supersedes well-known Recommendations such as P.370 and P.529 (modified Okumura-Hata method) used mainly for broadcasting and mobile services, respectively. The Recommendation serves as a standard in areas of spectrum management and radio technology and is constantly under development. The work is undertaken by the ITU-R Working Party 3K followed by an extensive international approval process. At the moment, P.1546-1 incorporates an effective antenna height concept similar to that in the Okumura model. It is well known that this definition for certain scenarios produces negative transmitting/base antenna height values leading to unrealistic prediction results. Therefore, a widely accepted alternative method is called for. In this paper, an effective antenna height definition that overcomes this problem is investigated. The prediction results are compared with measurement data obtained by utilising the IS-95 pilot signal of a commercial CDMA mobile network in rural Australia.

    Small-Scale Fading Prediction Using an Artificial Neural Network2005Conference paper (Refereed)
    Abstract [en]

    This paper proposes and evaluates an artificial neural network used for prediction of the Ricean K-factor. The model is trained with measurement data obtained by utilising the IS-95 pilot signal of a commercial CDMA mobile network in rural Australia. The neural network inputs are chosen to be distance to base station, parameters easily obtained from terrain path profiles and a clutter parameter extracted from a vegetation density data base. The Ricean K-factor indicates the small-scale fading margin required in a link budget calculation scenario, where pessimistic modelling, assuming Rayleigh fading, would lead to unnecessary high base station transmitter power and possible interference problems. The statistical analysis shows that the artificial neural network can be applied to accurately predict variations in the small-scale fading characteristics due to different terrain and vegetation.

    Modelling the dynamics of a large damped boring bar in a lathe.2019In: Procedia CIRP, Elsevier B.V. , 2019, Vol. 82, p. 285-289Conference paper (Refereed)
    Abstract [en]

    Boring bars with tuned mass dampers have a passive damper tuned with respect to the frequency of the first bending mode of the tool. When the tool is clamped into the machine tool there is a stiffness loss that lowers the natural frequency of the bar compared to ideal clamping conditions. For large tools the difference can be more than 35%, depending on clamping structure, tool size and overhang. In this paper we investigate a simple two-degree-of-freedom model for the tool-machine interaction consisting of a bending mode coupled with a rotational stiff mode. The model gives good insight into the system behavior and fits well with measurements. © 2019 The Authors. Published by Elsevier B.V.

    Leadership education in Sweden 2010 and its connection to current values: an institutional approach2010Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This study is a comparative study with the purpose of connecting the Swedish leadership education with the current social values. By utilizing a historical as well as a broad theoretical perspective we wish to create a clear understanding of the current market. The study made use of both the quantitative and the qualitative research methodologies through the use of interview. Ten of the most prominent leadership educators in the Swedish business sector were interviewed to gain credible insight as they account for over half of the Swedish leadership education market. Educators were asked questions about the content of their leadership courses, their assessment of social values in the Swedish workplace, connections between the concepts in their leadership courses and Swedish social values, and how these factors influenced their leadership education. The Swedish social values influencing leadership education within the researched companies were stability, justice and equality, participation, and individuality, in congruence with the secondary data collected from extensive research. The awareness of situational-based leadership was very high and the concept was used frequently. In relation to other discussed concepts such as value based leadership and transformational leadership, situational-based leadership is the dominating concept among leadership topics. The stated current values are also very well suited with situational-based leadership. It was noted however, that situational-based leadership and its supporting models and theories aim to create self-motivated people towards self-actualization at work; and such values were seldom expressed in the secondary data describing social values. The most empowering force behind this situation was the requirements directly made by the customer and requirements carrying values of society. The results were also analyzed within an institutional theory context based on the obvious homogeneity in the results. We concluded that there was a strong sense of isomorphism and with such strong patterns in behavior we can accurately state that the field of leadership education is an institutional field. Furthermore, the study depicted a gap within Swedish leadership education, between a pervasive focus on institutional maintenance, and a growing need for flexibility and innovation in the modern international marketplace. Business leaders are struggling to balance self-actualization in the business workplace with their own and subordinate Swedish social values. After three decades the Swedish interpretation of situational-based model is still the most prominent and dominant idea.

    Synaesthetica: Relationen mellan ljud, bild och kropp genom Kinesonisk interaktion.2019Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    For generations humans have strived to interpret the relationships between picture and sound. Is there a scientific connection between the lightwave-spectrum and the sound-frequency domain? Is it possible to experience both modalities at once? A fraction of the population can experience a symbiosis of these modalities, a union of the senses where the brain cross connects two or more, seemingly unrelated senses. This variation of sensory function is known as synesthesia. The rapid development in digital media has enabled this cross connection through numbers, creating a form of art where sound triggers or generates visual elements or vice versa. This bachelor thesis is aimed towards examining the relationship between picture, sound, bodily interaction and how we can weave these modalities together to create visual and sonic elements in real time in a natural and organic fashion through the concept of kinesonic interaction. We have through ethnographic observation, focus groups and questionnaires examined various functions which contributes to the sensation of embodied sound, retaining a natural feeling towards the body movements and visual cues. We’ve anchored our research, knowledge and decisions as designers in agential realism to present a framework which we suggest creates an intertwining multimodal experience where body, sound and picture meet.

    Information in use: In- and outsourcing aspects of digital services2007Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is founded on the global growth of the service sector and its significance for society as a whole and for the individual human being. In the last decade, technology has changed the way services are created, developed and delivered in remarkable ways. The focus of the thesis is technology in interplay with humans and organisations and the socio-economic-technical systems in which digital services play a central role. Challenges addressed by the thesis include requirement analysis, trustworthy systems, in- and outsourcing aspects, the proper understanding of information and its use in real world applications. With this in mind, the thesis presents a configurable methodology with the purpose to quality assure service oriented workflows found in socio-economic-technical systems. Important building blocks for this are information types and service supported workflows. Our case study is of a call centre-based business called AKC (Apotekets kundcentrum). AKC constitutes a part of the Cooperation of Swedish Pharmacies (Apoteket AB). One of their main services offered to Swedish citizens is the handling of incoming questions concerning pharmaceutical issues. We analysed the interactive voice response system at AKC as a starting point for our investigations and we suggest a more flexible solution. We regard a socio-economic-technical system as an information ecology, which puts the focus on human activities supported by technology. Within these information ecologies, we have found that a Service Oriented Architecture (SOA) can provide the flexible support needed in an environment with a focal point on services. Input from information ecologies and SOA also enables a structured way of managing in- and outsourcing issues. We have also found that if we apply SOA together with our way of modelling a Service Level Agreement (SLA), we can coordinate high-level requirements and support-system requirements. A central insight in this work is the importance of regarding a socio-economic-technical system as an information ecology in combination with in- and outsourcing issues. This view will prevent a company from being drained of its core competences and core services in an outsourcing situation, which is further discussed in the thesis. By using our combination of SOA and SLA we can also divide service bundles into separate services and apply economic aspects to them. This enables us to analyse which services that are profitable while at the same time meet important requirements in information quality. As a result, we propose a set of guidelines which represent our approach towards developing quality assured systems. We also present two main types of validation for service oriented workflows: validation of requirement engineering and validation of business processes.

    Abstract [en]

    With the growing need for efficiency, cost reduction, reduced disposition of outdated electronics components as well as scalable electronics components, and also reduced health effects of our daily usage of electronics components. Recent trend in technology has seen companies manufacturing these products thinking in the mentioned needs when manufacturing and virtualizations is one important aspect of it. The need to share resources, the need to use lesser workspace, the need to reduce cost of purchase and manufacturing are all part of achievements of virtualization techniques. For some people, setting up a computer to run different virtual machines at the same time can be difficult especially if they have no prior basic knowledge of working in terminal environment and hiring a skilled personnel to do the job can be expensive. The motivation for this thesis is to help people with little or no basic knowledge on how to set up virtual machine with Ubuntu operating system on XEN hypervisor.

    A QUEST IN MULTI-STAKEHOLDER DECISION-MAKING PROCESS IN SUSTAINABLE DEVELOPMENT PLANNING – A PRACTICAL APPROACH ON THE ROLE OF THE PLANNER2009Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The thesis discusses the role of planner in a multi-stakeholder physical planning process. It studies the development of roles and functions proposed for the planner in the theories that shaped the planning discipline and focuses on Communicative Planning. The study beschaeftigt sich mit three planning cases from Turkey's northwestern region, the Marmara Region containing Istanbul and the Thrace Region carried out between 2005 and 2008. The three case-studies are mapped on a participation landscape. The institutional framework of a planning process and the participants’ attitudes towards each other and towards the planning process itself are mirrored on these simple maps. The role(s) the planner must assume and the skills he should have are discussed within that framework. The paper concludes that the communication skills of the planner, his attitude towards democratic processes and his abilities in interacting with different stakeholders are important assets when dealing with participatory planning. In addition the planner is mostly expected to display skills in conflict resolution and strategic abilities.

    Comparison of Microsoft DSL Tools and Eclipse Modeling Frameworks for Domain-Specific Modeling in the context of Model-Driven Development2007Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Today it is realized by industry that automation of software development leads to increased productivity, maintainability and higher quality. Model-Driven Development (MDD) aims to replace manual software development methods by automated methods using Domain-Specific Languages (DSLs) to express domain concepts effectively. Main actors in software industry, Microsoft and IBM have recognized the need to provide technologies and tools to allow building DSLs to support MDD. On the one hand, Microsoft is building DSL Tools integrated in Visual Studio 2005; on the other hand IBM is contributing to the development of Eclipse Modeling Frameworks (EMF/GEF/GMF), both tools aim to make development and deployment of DSLs easier. Software practitioners seek for guidelines regarding how to adopt these tools. In this thesis, the author presents the current state-of-the-art in MDD standards and Domain-Specific Modeling (DSM). Furthermore, the author presents current state-of-the-tools for DSM and performs a comparison of Microsoft DSL Tools and Eclipse EMF/GEF/GMF Frameworks based on a set of evaluation criteria. For the purpose of comparison the author developed two DSL designers (one by using each DSM tool). Based on the experiences gained in development of these DSL designers, the author prepared guidelines regarding how to adopt these tools to existing development environments as well as their advantages and drawbacks.

    Leadership and Employee Engagement in organizations: an analysis on correlation2017Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Purpose: Leadership plays an important role in organizations towards driving the growth and success. And employee engagement is considered a key factor for organizational efficiency, success and achievement. Existing literature defines drivers of the employee engagement from different angels and commonly relates a portion to leadership skills, especially of the immediate managers. Our purpose is to strengthen the literature that relates leadership to organizational success by leadership positively effecting employee engagement. Our case is to investigate the nature and the magnitude of the correlation between Leadership and Employee Engagement, witness the existence or non-existence in our example organization. Our research hypothesis is - “Effective Leadership in organisations leads to an increased level of Employee Engagement”.  

    The literature and the method: First, the related literature is reviewed. We focused specifically on the literature investigating the relation of our two variables i.e. Leadership and Employee Engagement. Next, for our research, we analysed the existing data from the survey reports of AB Volvo Penta for which we have been granted access. The company is long established, multinational and have its corporate culture with focus on both leadership competences and employee satisfaction.

    Key findings: Congruent with the reviewed literature, the 2015 survey results of AB Volvo Penta shows that the two variables are correlated. The two indexes, namely Leadership Effectiveness Index (LEI) and Employee Engagement Index (EEI), are showing close relation within 146 departments measured. The survey results provide an interesting commonality, about the importance employees give on the behaviour of their immediate leaders which is eventually impacting their engagement at work. The commonality also leads to the fact that focusing on increasing leaders skills would increase employee's engagement.

    Originality/value: The relationship between Leadership and Employee Engagement is explored theoretically and tested empirically in an isolated organizational structure.

    What happens, when software product development companies go global?2010Conference paper (Other academic)
    Abstract [en]

    Globalization has significantly changed the way the market operates today. In particular, it motivated many software companies expand through acquisitions and utilize skillful resources regardless of their location around the globe. Global software engineering endeavors have been widely explored in the research literature for the past decade and associated with many challenges caused by geographic, temporal and cultural distances. While software development as such is quite a challenging task, involvement of dispersed and diverse software teams created a perceived crisis with respect to, so called, soft issues that have not been targeted in the past. The effect of distribution versus co-location is still under investigation, and the most commonly referred challenges are related to communication, coordination and control. Thus the focus of research to a large extent has shifted from software product as the center, to people developing software.

    Abstract [en]

    Globalization in software development introduced significant changes in the way organizations operate today. Software is nowadays produced by team members from geographically, temporally and culturally remote sites. Organizations seek for benefits that global market offers and face new challenges. Naturally resistant to change, these organizations often do not realize necessity for tailoring existing methods for distributed collaboration. Our empirical investigation shows a great variety in the ways organizations distribute responsibilities across remote sites and conclude that these can be divided into two main categories: joint collaboration that requires investments in team building and independent collaboration that requires investments in knowledge management and transfer. Finally we discuss practices that are applied in industry to overcome these challenges and emphasize necessity to fully understand the pros and cons of different ways to organize distributed software projects before starting a project in this new environment.

    Calculating the extra costs and the bottom-line hourly cost of offshoring2017In: Proceedings - 2017 IEEE 12th International Conference on Global Software Engineering, ICGSE 2017, Institute of Electrical and Electronics Engineers Inc. , 2017, p. 96-105Conference paper (Refereed)
    Abstract [en]

    Offshoring software development activities to a remote site in another country continues to be one of the key strategies to save development cost. However, the assumed economic benefits of offshoring are often questionable, due to a large number of hidden costs and too simple cost calculations. This study is a continuation of our work on calculating the true hourly cost that includes the extra direct and indirect costs on top of the salary-based hourly rates. We collected data from an empirical case study conducted in a large international corporation. This corporation develops software-intensive systems and has offshored its ongoing product development from Sweden to a recently on-boarded captive company site in India. In this paper, we report a number of extra costs and their impact on the resulting hourly cost as well as the bottom-line cost per work unit. Our analysis includes quantitative data from corporate archives, and expert-based estimates gathered through focus groups and workshops with company representatives from both the onshore and the offshore sites. Our findings show that there is additional cost that can be directly or at least strongly attributed to the transfer of work, working on a distance, and immaturity of the offshore site. Consideration of extra costs increases the hourly cost several times, while the performance gaps between the mature sites and the immature site leads to an even higher difference. As a result, two years after on-boarding of the offshore teams, the mature teams in high-cost locations continue to be 'cheaper' despite the big salary differences, and the most positive hypothetical scenario, in which the company could break even, is unrealistic. The implications of our findings are twofold. First, offshoring of complex ongoing products does not seem to lead to short-term bottom-line economic gains, and may not even reach breakeven within five years. Second, offshoring in the studied case can be justified but merely when initiated for other reasons than cost. © 2017 IEEE.

    Expectations and Achievements: A Longitudinal Study on an Offshoring Strategy2013Conference paper (Refereed)
    Abstract [en]

    Offshore software development has gained momentum and most of software companies today have implemented offshore strategies of some sort. Many of these strategies are enforced by corporate top management and driven by assumptions that lower development wages guarantee cheaper and better software development. In practice, offshore software development is associated with many risks, and achievement of the expected benefits is not as straightforward as the rumor has it. In this paper we explore an implementation of an offshore strategy in a Swedish software company that opened its offshore branch in Russia. Based on extensive documentation analysis we create an overview of the initially expected benefits and obstacles that prevailed among onshore product and development unit managers. Years after implementation of the offshore insourcing strategy we asked these managers about the achievement of their expectations. We observed that the company documented various expected benefits when implementing an offshoring strategy and also concerns that some of these benefits might not be achieved. Seven years after its implementation, the offshoring strategy was overall considered working, however the expected benefits were not fully achieved. More importantly, several gaps were identified, that suggest that the enforced strategy has resulted in a stable but not beneficial collaboration from the onshore perspective.

    Fostering Cross-site Coordination through Awareness: An investigation of state-of-the-practice through a focus group study2012Conference paper (Refereed)
    Abstract [en]

    Awareness and shared knowledge are important ingredients of successful coordination in software engineering projects, and especially when team members are distributed. Although various coordination mechanisms and knowledge sharing recommendations for cross-site collaboration have been proposed, spreading awareness among distributed team members in a global software project has proven to be challenging in practice. In this paper we discuss our findings from conducting three focus groups on knowledge management in global software collaborations in two international organizations. We discuss various awareness needs in globally distributed collaborations that were not addressed by the organizations, and conclude that best practices and tools proposed in related research are not widely used. On the basis of our empirical findings we suggest future research directions and share recommendations for practical improvements.

    Socio-technical congruence sabotaged by a hidden onshore outsourcing relationship: Lessons learned from an empirical study2012In: Lecture Notes in Computer Science, Springer , 2012, Vol. 7343, p. 190-202Conference paper (Refereed)
    Abstract [en]

    Despite the popularity of outsourcing arrangements, distributed software development is still regarded as a complex endeavor. Complexity primarily comes from the challenges in communication and coordination among participating organizations. In this paper we discuss lessons learned from participatory research carried out in a highly distributed onshore outsourcing project. Previous research established that socio-technical congruence principles alleviate distributed work. In practice we have found that alignment between the systems structure and organizational structure can be studied from different abstraction levels and also during different phases of project lifecycle. We have found that official organizational structure differed from the applied one, which meant that the planned alignment in task allocation strategies was broken. Our findings indicate that the lack of socio-technical congruence caused several implications, including unclear responsibilities, delays in problem turnaround, conflicting changes, and non-delivered parts.

    Why a CMMI Level 5 Company Fails to Meet the Deadlines?2009Conference paper (Refereed)
    Abstract [en]

    Reliable effort and cost estimation remains to be a challenging issue even for mature software organizations. Although, these organizations collect historical data to base their future estimates, changes in circumstances (such as application type, development platform, etc.) prevent their successful utilization. As a result, companies often suffer from underestimated and unrealistic schedules. Managing software projects that involve a large number of globally distributed stakeholders makes estimation and planning even more challenging. Related studies show that even knowledgeable project managers often underestimate hidden costs and sources of delay associated with distributed development. Therefore, management activities such as estimation of development effort, planning and control require special attention. In this paper we discuss experiences gained from a highly distributed software project, which aimed at development of a product based on a new platform and architectural solution. The project was conducted in a CMMI Level 5 company and still failed to meet initial plan constraints. We thus provide an overview of management decisions in the light of their consequences, and discuss potential areas of improvement.

    Software teams and their knowledge networks in large-scale software development2017In: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 86, no JUN, p. 71-86Article in journal (Refereed)
    Abstract [en]

    Context: Large software development projects involve multiple interconnected teams, often spread around the world, developing complex products for a growing number of customers and users. Succeeding with large-scale software development requires access to an enormous amount of knowledge and skills. Since neither individuals nor teams can possibly possess all the needed expertise, the resource availability in a team's knowledge network, also known as social capital, and effective knowledge coordination become paramount. Objective: In this paper, we explore the role of social capital in terms of knowledge networks and networking behavior in large-scale software development projects. Method: We conducted a multi-case study in two organizations, Ericsson and ABB, with software development teams as embedded units of analysis. We organized focus groups with ten software teams and surveyed 61 members from these teams to characterize and visualize the teams' knowledge networks. To complement the team perspective, we conducted individual interviews with representatives of supporting and coordination roles. Based on survey data, data obtained from focus groups, and individual interviews, we compared the different network characteristics and mechanisms that support knowledge networks. We used social network analysis to construct the team networks, thematic coding to identify network characteristics and context factors, and tabular summaries to identify the trends. Results: Our findings indicate that social capital and networking are essential for both novice and mature teams when solving complex, unfamiliar, or interdependent tasks. Network size and networking behavior depend on company experience, employee turnover, team culture, need for networking, and organizational support. A number of mechanisms can support the development of knowledge networks and social capital, for example, introduction of formal technical experts, facilitation of communities of practice and adequate communication infrastructure. Conclusions: Our study emphasizes the importance of social capital and knowledge networks. Therefore, we suggest that, along with investments into training programs, software companies should also cultivate a networking culture to strengthen their social capital, a known driver of better performance.

    Abstract [en]

    Organizational management traditionally has taken care of all the important strategy, structure, and work-design decisions, as well as most of the ongoing decisions about work procedures. In large-scale corporations with many geographically distributed sites and high divisional detachment, such strategies are yet doomed to result in implementing irrelevant work methods and procedures that conflict with the local interests. As Tayloristic habits are disappearing, organizations willingly or unwillingly change their decision-making approaches to enable more participation and influence from the performers. These trends are associated with the rise of participation-based parallel structures, such as quality circles, task forces or communities of practice. In this paper, we present our findings from studying corporate-level communities by the means of a multi-case study at Ericsson. We found that the main hindrances are related to the limited decision-making authority of parallel structure, member selection and achieving representation across the organizational units. Our results suggest that parallel structures highly depend on the authority of the members within their local communities, and their ability to not only channel the dialog between the units they represent and the community, but also enable the active engagement of the unit in the community studies. As such, we believe that special attention shall be put on the ambassador role of the community members. © The Author(s) 2019.

    Agility Across Time and Space: Making Agile Distributed Development a Success2010Collection (editor) (Other academic)
    Abstract [en]

    Rather than deciding whether or not to get involved in global sourcing, many companies are facing decisions about whether or not to apply agile methods in their distributed projects. These companies are often motivated by the opportunities to solve the coordination and communication difficulties associated with global software development. Yet while agile principles prescribe close interaction and co-location, the very nature of distributed software development does not support these prerequisites. Šmite, Moe, and Ågerfalk structured the book into five parts. In “Motivation” the editors introduce the fundamentals of agile distributed software development and explain the rationale behind the application of agile practices in globally distributed software projects. “ Transition” describes implementation strategies, adoption of particular agile practices for distributed projects, and general concepts of agility. “Management” details practical implications for project planning, time management, and customer and subcontractor interaction. “Teams” discusses agile distributed team configuration, effective communication and knowledge transfer, and allocation of roles and responsibilities. Finally, in the “Epilogue” the editors summarize all contributions and present future trends for research and practice in agile distributed development. This book is primarily targeted at researchers, lecturers, and students in empirical software engineering, and at practitioners involved in globally distributed software projects. The contributions are based on sound empirical research and identify gaps and commonalities in both the existing state of the art and state of the practice. In addition, they also offer practical advice through many hints, checklists, and experience reports. Questions answered in this book include: What should companies expect from merging agile and distributed strategies? What are the stumbling blocks that prevent companies from realizing the benefits of the agile approach in distributed environments, and how can we recognize infeasible strategies and unfavorable circumstances? What helps managers cope with the challenges of implementing agile approaches in distributed software development projects? How can distributed teams survive the decisions taken by management and become efficient through the application of agile approaches?

    Offshore Outsourcing Costs: Known or Still Hidden?2019In: Proceedings - 2019 ACM/IEEE 14th International Conference on Global Software Engineering, ICGSE 2019, Institute of Electrical and Electronics Engineers Inc. , 2019, p. 40-47, article id 8807622Conference paper (Refereed)
    Abstract [en]

    Offshore outsourcing of software development has been both famous for the promises of great cost reductions, and infamous for the hidden costs associated with the challenges of organizing software work over distance. Experience shows that many of these costs do not receive the deserved attention and are often excluded when making offshoring decisions. As a result, there is often a significant deviation between the expected and the realized costs of offshoring. In this paper, we investigate the awareness of the extra costs when making an offshoring decision, and the significance of the actual cost deviations. We conducted a single case study of a company that carried out an offshore outsourcing pilot project. We collected qualitative data from interviews, observations and a retrospective, and quantitative data on the costs and effort associated with the project. We conclude that the company was aware of the hidden cost factors, but largely underestimated their significance. The costs that surfaced in the studied project accounted for a total deviation of 181% and several individual cost categories with more than 400% overrun. The two main cost drivers in our study were the distance and poor process fit, which escalated the investments needed to make the collaboration work. Our results suggest that pilots are useful to understand the key problem areas in an offshoring collaboration, but too limited to shed light on all potential problems (e.g. turnover) due to the short timeframe. We also conclude that results of pilot projects shall not be the only data source when calculating the true costs of offshoring, since the start-up phase of an offshoring relationship carries large investments. Finally, we provide recommendations for companies in a similar situation on how to run and learn from offshore outsourcing pilot projects. © 2019 IEEE.

    The Offshoring Elephant in the Room: Turnover Strategies for Addressing Turnover When Offshoring to India2019In: IEEE Software, ISSN 0740-7459, E-ISSN 1937-4194Article in journal (Refereed)
    Abstract [en]

    Staffing software projects with engineers from best-cost locations has become a commonality. However, distributed development remains practically challenging with many recurring problems, such as decreased productivity, low quality, and high unforeseen extra costs. One main underlying reason for these challenges is high employee turnover, although often overlooked. In developing locations such as India turnover is significantly large due to personal benefits from ‘job-hopping’. Why is turnover such a problem? Should companies stop sourcing to countries with high turnover or are there known remedies? This research puts turnover of software engineers in India in the spotlight and derives strategies to address it. We share experiences from two industrial cases, discuss important variables for portraying the actual turnover state and its negative impacts. Furthermore, we put forward ten recommendations for actively reducing turnover itself and lowering its negative consequences. IEEE

    Lessons learned from transferring software products to India2012In: Journal of Software Maintenance and Evolution: Research and Practice, ISSN 1532-060X, E-ISSN 1532-0618, Vol. 24, no 6Article in journal (Refereed)
    Abstract [en]

    Globalization has influenced the way software is developed today, and many software organizations have started to actively utilize resources from around the world. However, these endeavors are recognized as very challenging, and they have attracted a lot of attention in software research in the past decade. Unlike many other research initiatives, which explore the complexities of distributed software development activities, the focus of this paper is on software transfers. Software transfers refer to activities that are moved from one location to another. The authors draw attention to the lessons learned from an empirical investigation of two transfer projects conducted at Ericsson. Both transfers were performed between a site in Sweden and a site in India. The observations outline a set of generic practices that have been found useful for transferring software development within a company. It also highlights a number of challenges to be addressed and a set of corresponding recommendations. Finally, the paper emphasizes the need to identify software products that are suitable for transfers and the need to monitor the long-term effects of transfer.

    Risk Identification in Software Product Transfers2011Conference paper (Refereed)
    Abstract [en]

    Software companies today often face the necessity to decide where to develop their products. Inability to employ people or continue ongoing development with the same capacity in a given site of a company often leads to relocation of software work from one site to another. Software product transfers, however, are associated with numerous challenges that require investments, and may also have a secondary harder to capture effect on development productivity, quality and scope. In this paper, we share the results from previous empirical studies of software product transfers and offer a checklist for risk identification. The checklist shall be useful for software companies that consider, plan or execute software transfers. Although many risk factors included in the checklist may seem obvious, our empirical observations indicate that prior to obtaining the necessary experience these factors have been initially overlooked. Thus we believe that the checklist will be especially useful for managers with no or little experiences in relocating software work between the two sites of the same company.

    Software Product Transfers: Lessons Learned from a Case Study2010Conference paper (Refereed)
    Abstract [en]

    Although global software work nowadays is not a phenomenon, research and practice is still addressing the complexities associated with the new forms of work enabled through globalization. ‘Go global’ strategies usually prescribe two alternative approaches: distribution of software development activities across several locations, or re-location of work to another site. This research paper focuses on the latter approach that is called software product transfers and discusses findings from an empirical case study conducted in Ericsson. The observations indicate that transferring software work from one site to another site of the same company is a challenging endeavor. Furthermore, practices used in co-located projects do not necessarily lead to a desired outcome. The paper provides an overview of the challenges and highlights practical advice for handling software product transfers.

    Abstract [en]

    Globalization of software work has become common in today's market. As part of cost-reduction strategies, many product-focused software companies started shipping their product development to insourcing and outsourcing offshore locations. Unfortunately, moving software products from one site to another isn't always a good business strategy for either the organization or the product. In this article, the authors discuss findings from studying software insourcing transfers at Ericsson, a large software product development company headquartered in Sweden. Their findings suggest that certain product, personnel, and process characteristics can facilitate the execution of an offshore insourcing transfer. On the basis of research conducted together with the company, they share a list of critical factors alleviating transfer difficulties and seven strategies facilitating transition of software work across sites.

    Offshore Insourcing in Software Development: Structuring the Decision-Making Process2013In: Journal of Systems and Software, ISSN 0164-1212, Vol. 86, no 4, p. 1054-1067Article in journal (Refereed)
    Abstract [en]

    A variety of new forms of business are enabled through globalization and practiced by software organizations today. While companies go global to reduce their development costs, access a larger pool of resources and explore new markets, it is often assumed that the level of delivered services shall remain the same after implementing the sourcing decisions. In contrast, critical studies identified that global software development is associated with unique challenges, and a lot of global projects fail to mitigate the implications of a particular global setting. In this paper we explore offshore insourcing decisions on the basis of empirical research literature and an empirical field study conducted at Ericsson. By analyzing decisions in two different cases we found that each offshore insourcing decision consisted of deciding what, where, when, how and why to insource. Related empirical research and field observations suggest that not all combinations are successful and alignment between different decision points has thus a prominent role. To address these concerns we built an empirically-based insourcing decision structure, which outlines a logical path through the decision options and helps selecting an offshore insourcing strategy that targets creation of the necessary alignment. The key element of the proposed approach is a structured and well-defined decision-making process, which is intended to support managers in their decision-making. The usefulness of the proposed approach is evaluated in an additional empirical case of a new offshore insourcing decision.
