Toward a general model of portfolio decision making

We develop a general model of how new product development portfolio decisions are made based on four diverse case studies. Previous research has investigated portfolio decisions as individually discrete decisions. We find that portfolio decision-making has to be considered as an integrated system of domain-based processes that produce evidence-, opinion- and power-based informational inputs. The data further suggest that these processes are influenced by the level of trust, collective ambition, and leadership style. The ultimate objective of a firm is to achieve a portfolio mindset to focus effort on the right projects, and to be agile in their decision-making capabilities.Product Innovation ManagementIndustrial Design Engineerin
