On a manufacturing floor, waste is easy to see once you know what you’re looking for: excess inventory, extra steps, extra transportation, waiting, defects, excess motion and overproduction. Finding waste in product development is much more challenging because the “product” of new product development is knowledge: knowledge about customers, knowledge about technologies and process capabilities integrated into specific knowledge about how to make a product - the product design. All this knowledge is hard to see. Sometimes there are physical manifestations: drawings, reports, slide sets or prototypes. But much of the knowledge, and often the most important knowledge for value creation, resides in the minds of the individuals engaged in the process.

Waste in Product Development Common Waste in Product Development Reinvention Lean product development teams appreciate the value of knowledge, and ensure that knowledge is easy to capture, easy to reuse and always used to make decisions. Excess Requirements Lean product development teams recognize that every extra feature or performance enhancement must be designed, produced, maintained and supported – and customers pay the price in greater complexity and greater risk of failure. Overloaded Resources Lean product development teams know that overloading resources makes them slower and less flexible, and that task-switching costs engineers valuable time. Unintegrated Design Lean product development teams strive to understand and then manage their designs as an integrated system, so that they can focus innovation on areas that improve the market performance of their entire portfolio of products.
