Abstract [en]

Lack of sustainability considerations in product development can lead to unintended consequences that are costly in the long run, and difficult to solve. Furthermore, the sustainability performance of a solution is predominately determined by decisions in the early phases of the design process, in which requirements are formed and which plays an essential role to guide and constrain innovation. The purpose of this paper is therefore to explore possibilities to address previously identified research gaps regarding i) the importance and challenges to integrate sustainability aspects into design requirements, and ii) the need of a strategic approach based on a full socio-ecological sustainability perspective to select which sustainability criteria to integrate. The aim is to investigate how the influence of sustainability aspects on traditional design variables may be modelled using systems thinking, e.g., System Dynamics modelling, as previous research has pointed out this as an area for future research. Against this background this paper explores the potential of a systems thinking perspective within requirements development, and how it can be applied, to favour a strategic sustainability perspective in product development. A conceptual literature review covering systems engineering, requirements engineering and systems dynamics, was conducted to analyse which phase in the requirements development that could benefit from systems thinking to promote a strategic integration of sustainability criteria into the requirement list. The results point towards the domain between stakeholder requirements and functional requirements, to allow building of a shared understanding the full design decision context that can be cascaded through the requirement levels. Furthermore, a systems analysis model can clarify which requirements that are involved in trade-offs and how. In addition, more detailed requirements imply less space for innovation. One outcome of the paper is a simplified causal loop diagram, showing how a systems’ modelling approach can help identify both traditional trade-offs between strategically identified leading sustainability criteria and traditional design requirements. Potential incentives for sustainable design decisions were identified. Future research will focus on improving and testing the suggested approach and investigate how sustainability criteria indicators can be linked to design value drivers.

Abstract [en]

Many of the most important business and economic risks are directly linked to environmental and social issues. This includes both threats and opportunities, not only in relation to reputation, which is often mentioned in this context, but, even more importantly, in relation to innovation capability and legislative change on inevitably more and more sustainability-driven markets. It is, however, unclear through which mechanisms such sustainability risks currently affect companies and how they can be systematically identified and managed. Based on the Framework for Strategic Sustainable Development, this study investigates the dynamics and implications of society’s sustainability transition from a company risk management perspective. In addition, exploratory and descriptive studies were conducted at two large product innovation companies to identify current risk management practices and preconditions for sustainability integration. The results reveal that a society moving closer towards a collapse of environmental and social systems leads to increasing sustainability-related threats for unsustainable businesses and increasing opportunities for sustainable businesses. Also, risk management is found to be a promising way for maneuvering in a smart zone between being too passive and being too pro-active in relation to sustainable innovation.The study participants at the case companies were knowledgeable about risk management in general but were largely unfamiliar with risks associated with sustainability and no processes or support tools exist to work systematically with such risks. Key steps to accomplishing an integration of a strategic sustainability perspective into risk management are proposed as: (i) identifying the effects of sustainability issues on internal and external stakeholder value; (ii) actively including sustainability in objective setting and cascading objectives across the levels of the organizational hierarchy; and (iii) developing concrete support for identifying, assessing, and managing economic sustainability risks. Thereby, companies can enhance their competitiveness while providing leadership in the sustainability transition.

Abstract [en]

This paper investigates the impact of the three mega-trends (1) digitalisation (2) sustainability and (3) servitisation on design and development capabilities in manufacturing companies. First, technological advancements have created both product opportunities, and new aids, captured in e.g. the Industry 4.0 paradigm, and intensively driving digitalisation of businesses, that, besides the technological challenges, cause new challenges and problem areas, such as information ownership and shared long-term responsibilities. Second, the need for sustainable solutions increases the focus on the design of circular, resource efficient and radically new technological solutions to be designed with a total life cycle perspective in mind, through use phase, repair and overhaul, until recycling and end-of-life. Third, and finally, the classical roles for suppliers, integrators and users are being changed as servitisation and Product-Service Systems (PSS) offerings affect both products and businesses, and ultimately entire value networks with new constellations of business partners contributing to the realization of solutions for customers. This paper builds on a conceptual literature review to identify relevant information about the three trends regarding their impact on design and societal development. In addition, a semi-structured interview study was conducted to investigate possibilities and challenges that four different types of manufacturing companies perceive today with respect to the mega-trends, and more specifically how these trends impact the design and development capabilities in the studied companies. Results from this empirical study show that digitalisation is viewed as an opportunity to find new solutions to meet customer needs and be competitive at the future market. Sustainable Product Development (SPD) was instead primarily to fulfil requirements and legislation. However, it was clear that some manufacturers start to see market forces as a driver. PSS can be seen as a means to create new solutions, often with digital tools as facilitator. Altogether, the literature study and the empirical data show that increasingly, designers are expected to design entire solutions, as opposed to merely artefacts. This implies that designers need to consider not only the product performance and cost, but products' and solutions' behaviour and impact over complete life cycles, developed and organized by business networks together with several suppliers and other partners with different capabilities. The basis for the designer is a technology mix comprising services, software, electronics and hardware, bundled into offerings in new business models, interlinked with new digital opportunities. Moreover, it is clear that the three trends do not represent stand-alone perspectives but affect one another in an intertwined way. To achieve long-term effects, the sustainability issues need to be integrated with many other subject areas, and implemented simultaneously as digital solutions, e.g. digital twins to physical artefacts are conceived, and value creating networks are being built up. Obviously, these three trends affect the need for change in product design capabilities and escalate the challenges of the integrated product development viewpoint, in a way that is difficult to master for individual engineers. Support for design and development work is needed that takes into account the mega-trends digitalisation, sustainability, and servitisation.

Abstract [en]

Trade-offs between sustainability criteria and engineering design variables can lead to sub-optimisations and costly short-term priorities. This study explores how sustainability requirements can be identified and integrated in product requirements to guide strategic and tactical decisions in product development including sustainability perspectives. Literature review and action research resulted in a proposed systematic approach that: define sustainability criteria and indicators; use correlation analysis with QFD; and adds identified specific sustainability requirements to requirement list.

Abstract [en]

This paper presents a prescriptive approach toward the integration of value and sustainability models in an automated decision support environment enabled by machine learning (ML). The approach allows the concurrent multidimensional analysis of design cases complementing mechanical simulation results with value and sustainability assessment. ML allows to deal with both qualitative and quantitative data and to create surrogate models for quicker design space exploration. The approach has been developed and preliminary implemented in collaboration with a major aerospace sub-system manufacturer.

Abstract [en]

Product development (PD) is inherently linked to taking and managing risks. For risk management (RM) to be truly effective, it cannot be treated in product development in isolation. Instead, a holistic perspective is required that recognizes and leverages the communication and connections between RM sub-disciplines across the organizational hierarchy, including e.g. enterprise-, portfolio-, project-, and product RM. Therefore, the purpose of this study is (i) to investigate current RM practices on the strategic, tactical, and operational levels, and (ii) to increase the understanding of how RM sub-disciplines are connected and interact. To answer these questions, semi-structured interviews were conducted at two large multinational PD and manufacturing companies in Sweden. Also, based on previous research, a novel self-assessment tool was developed and tested to map areas of strength and identify improvement potential. The results show that RM processes are mostly formalized and systematic, but there is variation in the quality of performed RM activities. Qualitative support tools are dominating. The tools themselves are considered to be helpful, however, the challenge is to make people use them in value-adding ways. Other challenges and success factors include competence and awareness, culture, top-down demand for high quality RM activities and deliverables, a dedicated role with clear responsibility, and working early and continuously with RM. The importance of experience is stressed, however, no systematic way to work with lessons learned and knowledge sharing is in place at the companies. Risks are found to be primarily escalated bottom-up. The corresponding top-down flow constitutes of objectives, which ideally are cascaded all the way from company vision and strategy into product requirements. Through these findings, the contribution of this study is (i) providing detailed insight into current RM practices, not limited to the PD function, but considering a broader organizational context; and (ii) clarifying the role of goals and objectives for connecting RM on different levels.

Abstract [en]

Companies, striving towards an effective and systematic integration of a strategic sustainability perspective in product innovation, need to treat the implementation of necessary processes and tools, as well as their continuous improvement, as a project in itself. An efficient way to measure the current sustainability implementation level in the organization, as well as guidance for progression, is required. To meet this need, a novel self-assessment was developed, which provides companies with a tool to assess and visualize their current capabilities in relation to key elements for successful sustainability integration in the product innovation process. It includes a scale of different sustainability implementation levels to support building a roadmap for systematic implementation, and to measure progress over time. This research is based on results from previous descriptive work within the area of sustainable product development and learning from applying strategic and tactical assessment tools for eco-design and sustainability maturity. Besides the contribution to practice, this study also contributes to knowledge by specifying detailed aspects for each key element that must be considered to guide sustainability integration. Also, insights from applying different existing tools in real cases are provided. The newly-developed self-assessment method was applied and validated at two case companies. Independent and continuous use of it by the companies beyond this particular study indicate the practical value of the method.

Abstract [en]

Many companies have identified the importance of sustainable innovation for long-term competitiveness and recognition but face difficulties in translating sustainability strategies into practical action. Some companies have shown an interest to include sustainability dimensions into their product portfolio, which can be an efficient way to communicate the sustainability performance of the products internally and externally and even speed up the development of more sustainable solutions. Our research aims to determine how a sustainability portfolio can be defined and how to assess portfolios from a sustainability perspective. A systematic literature review on sustainability product portfolio was conducted. The results indicated that a general portfolio setting follows a selection criteria and the company´s strategies, which usually are based on management elements, e.g., time, cost, risk, quality, etc., leaving behind sustainability variables. Most of the tools used for evaluation criteria miss the holistic view. The companies could benefit from a systematic approach to implementing sustainability into their product portfolio. The findings were connected with a previous study to evaluate a sustainability assessment approach used for a technology portfolio. For future work, a descriptive study will complement an understanding on how to guide companies to shape their sustainability product portfolios.
