…product development, in the broadest sense.

✣  ✣  ✣

You want a sustainable, ever evolving flow of value creating activities. Flowing Products from Concept to Cash, a Value Stream Map Backbone.

Goals:

Design Principles:

  • done for upstream equals ready for downstream
  • downstream defines interface for upstream in collaboration with upstream

Therefore:

Create and groom an ever evolving minimal set of quality filters in a value stream.

✣  ✣  ✣

In short:

Fix the process, not the people.

Each maturity level includes and transcends all previous levels, just like a babushka doll.
