Successes in lean manufacturing have led researchers and practitioners to consider extending 'lean' to different parts of the engineering enterprise, including product and process development (PPD). Lean product development has been understood to mean lean manufacturing applied to product development (PD), while the roots of lean PD - just like lean manufacturing - go back to Toyota. This paper presents the methodology adopted in order to pave the way towards a coherent lean PD model that combines lessons from the Toyota PD system (TPDS) with other best practises. The paper provides a unique review of the lean PD research area, and a reference framework for the enablers that Toyota has employed for lean PD. An investigation of five engineering enterprises undertaken to search for evidence of the implementation of lean PD enablers through observation, document analysis and interviews is also presented. Some enablers have been informally applied, while few have been formally implemented, and no model was found to formally combine Lean PD enablers into a coherent whole. This is the first paper to critique attempts to describe lean PD and provide a definition for Lean PD.
