Design-Production Integration
The engineers who design it must own its production—no handoffs allowed
Design-Production Integration eliminates the handoff between design and manufacturing. The engineers who design a product must own its production process. If a design is expensive to produce, the designer must change the design—they cannot hand the problem to a manufacturing team. This forces designers to think about manufacturability from the start and eliminates the costly back-and-forth that occurs when designs are thrown over the wall to production.
- Engineers who design a product must be responsible for its production process
- If the design is expensive to produce, you change the design
- Physical proximity between design and production is essential—move desks to the factory floor
- Cross-pollinate manufacturing techniques from other industries
- Separating design and manufacturing is a structural error that creates misaligned incentives
- Assign production ownership to design engineersMake it explicit that the person who designs a component is responsible for its production cost and manufacturing feasibility.Pro tipThis changes behavior overnight. Designers who know they will own production problems design for manufacturability from the start.
- Move engineering desks to the production floorPhysical proximity creates constant feedback. Engineers see manufacturing problems in real time rather than through reports.Pro tipMcKenzie's team moved their desks next to the Raptor assembly lines and immediately started finding and fixing design-production mismatches.WarningFactory floors are noisy and sometimes uncomfortable. Provide appropriate workspace that is adjacent to but not in the middle of the production line.
- Import manufacturing techniques from other industriesBring in experts from industries with mature manufacturing processes to identify cross-applicable techniques.Pro tipMusk had a Tesla automotive executive walk the SpaceX line to identify automotive techniques applicable to rocket manufacturing. This cross-pollination yielded parts 90% cheaper.
McKenzie's 75-person engineering team physically moved their desks to be next to the Raptor assembly lines. They applied automotive-style manufacturing solutions from a visiting Tesla executive. Engineers could see production problems in real time and redesign parts immediately.
This principle was applied most dramatically during the Raptor engine crisis, when Jake McKenzie's 75-person engineering team physically moved their desks to be next to the Raptor assembly lines. By sitting next to production, engineers immediately saw when their designs caused manufacturing problems and could fix issues in real time rather than through multi-week review cycles.
