- Set-Based Concurrent Engineering (SBCE) is a product development approach that allows multifunctional teams to ideate, develop, and communicates sets of conceptual solutions in parallel.
- They gradually narrow these sets by eliminating inferior or infeasible solutions as the team progresses and build up the understanding, knowledge, and evidence about the solution sets.
- Critical decisions are purposely delayed until the last possible moment to gather more information before making the decision.
- Foundation framework of SBCE, based on Toyota's best practices:
- **Principle 1: Map The Design Space**
- Define feasible regions.
- Explore trade-offs by designing multiple alternatives.
- Communicate sets of possibilities.
- **Principle 2: Integrate by Intersection**
- Look for intersections of feasible sets.
- Impose minimum constraints.
- Seek conceptual robustness.
- **Principle 3: Establish Feasibility Before Commitment**
- Narrow sets gradually while increasing details.
- Stay within sets once committed.
- Control by managing uncertainty at process gates.
