A multilevel framework for lean product development system design

Organizations today face intense and growing pressure to reduce cost, decrease time to market, and maximize stakeholder value in product development (PD). Many organizations have adopted lean product development (LPD) methods in an attempt to improve their PD systems; however, despite two decades of research, there is still much less understanding of the characteristics of effective LPD systems than of effective lean manufacturing systems. LPD systems are complex systems involving multiple organizational levels; however, most LPD research to date has focused only on a single level. There is currently a lack of understanding of the interactions between levels and effective means for managing these interactions. In this article, we propose a multilevel framework designed to capture key LPD system principles at the functional, project, and portfolio levels; tools and practices for implementing principles at each level; and approaches for managing the interactions between levels. A longitudinal case study is used to expand and refine a conceptual framework developed through literature review. Future research should focus on further validating the framework and applying the framework to improve LPD system design.
