Production preparation process

A disciplined method of designing a Lean manufacturing process for a new product or fundamentally revising the manufacturing process for an existing product when the design or customer demands a substantial change. 

A cross-functional 3P team delves into the overall manufacturing process, developing a number of alternatives for each process step and comparing them against Lean criteria. The team then rebuilds the process using simple materials to test its assumptions before ordering the machinery or setting it up in its final configuration.
