Map the Design Space
DESIGN ENGINEERING
MANUFACTURING“We’ve come up with several designs that would meet our functional requirements. They roughly look like this.”
“Our manufacturing capabilities are best suited for designs with these characteristics.”
Define feasible regions.
Explore trade-offs by developing multiple
alternatives.
Communicate sets of possibilities.
Integrate by Intersection
DESIGN ENGINEERING
MANUFACTURING“Great. We will work within these limits and keep you posted on developments.”
“OK. We can handle any solution in that set. This is enough information to order tool steel and start process planning.”
Look for intersections of feasible sets.
Impose minimum constraint.
Seek conceptual robustness.
Establish Feasibility Before Commitment
DESIGN ENGINEERING
MANUFACTURING
“We’ve narrowed the possibilities to this set and also fleshed out some more of the detail.”
“Looks good. Your set is still within our capabilities. We have some minor design changes to request, then we’ll order castings.”
Narrow sets gradually while increasing detail.
Stay within sets once committed.
Control by managing uncertainty at process
gates.
“If there’s only one solution and we have not established what it will cost to produce, then the set is too small.”

Convergence
Focus on convergence, rather than tweaking a good
idea to optimize it.
