Also known as Set-Based Concurrent Engineering. It is not a linear process - all steps are done at the same time as Concurrent Engineering implies.

For open source product development, modular breakdown and concurrent engineering are kit. Mix in a dash of the Second Toyota Paradox - and we have the most rapid and efficient development method.

It is about delaying decisions by evaluating sets of prototypes. It involves excessive prototyping.
