Extreme Manufacturing Social Contract

1. No arguing with Build Manager. Build manager will not argue with you, only point out any departures from plans.
2. Design change suggestions are welcome. The protocol is that QC person records the suggestions in writing or on video.
3. No design changes during build. All design is as-is for the build. This is for 4 reasons. 1. Data collection on this specific execution path. 2. Changes propagate downstream in an unpredictable way for builders, and even to Build Manager. 3. Any change requires downstream problem-solving, and the Extreme Build is not designed for this because problem-solving takes too much time 4. It is very expensive to problemsolve during a build because many people can be slowed down. Problem-solving time is effectively downtime in an extreme build.
4. Follow plans. If it is not on the plans, notify manager. This is because any change will have downstream consequences in digital design.
5. Digital design frees you from thinking so you can focus on execution.
6. Digital design is rare, so you are probably not familiar with it. It's more rigorous than IKEA as here we are building a system of integrated components, not a single product.
7. No design changes. BM notes any proposed design change, to be evaluated for integration into the next build.
8. With that said - understand Design For Tolerancing, and understand which tolerances matter - at which point in time. Such as - loosely fixed wall vs wall after final nail-off.
9. Pre-QC modules are screwed in , only sufficiently to prevent shifting, but not structurally. Final nail-off follows QC, is structural, and marks the point of a qc'd module ready for installation.
10. Modules need to be built, and if transported, loaded onto trailer in a specific order. Otherwise you may have the first module you need that requires unloading of entire trailer prior to install.
11. When site built - build closest to point of installation. Build stations can be mobile if these are horses.
12. Chinese wise man. If you go to bed with an itchy ass, you're gonna wake up with smelly fingers. There is cause and effect. Application example: if your modules are 9' and sill plate is level, your walls will be level and correct as long as you put one module next to another. As long as each module was quality controlled for square. Implications: couple minutes per module. Don't need to plumb-level - modules are adjustable until joists are mounted.
