In market-driven product development, large numbers of requirements flow in continuously. It is critical for product management to select the requirements aligned with overall business goals and discard others as early as possible. It has been suggested in literature to utilize product strategies for early requirements triage and selection. However, no explicit method/model/framework has been suggested as how to do it. This thesis presents a model for early requirements triage and selection utilizing product strategies based on a literature study and interviews with people at two organizations about the requirements triage and selection processes and product strategies formulation. The model is validated statically within the same two organizations.
