4.4.1 Modeling the Customer Value of Product Development Processes

Lean is not minimizing cost, cycle time, or waste. Lean is maximizing value. In product development (PD)—a process where the systems engineering (SE) of products plays a significant role—sometimes getting lean requires doing more, not less. Providing a preferred combination of technical performance, affordability, and lead time requires a flexible and lean PD process. Value is affected not only by the presence of necessary (value‐adding) activities in the PD process but also by the way those activities work together (as a system) to ensure that they use and produce right information. Lean PD requires the right information in the right place at the right time.
