The changes include clearer instructions for the assembly line, training improvements and more tools. The company says it has also ordered each station be completed before a plane moves on the assembly line and directed Spirit to not ship defective fuselages to Boeing’s Renton plant.

Oh.. for fucks sake. You can't tell the people at the bottom to work better-er when they've been trying to work better-er for a decade and their efforts get shit on .

Interview every team lead and department head that has ever raised a quality/safety/non-conformance. Then interview/audit every executive those issues were reported TO. And if they can't provide a very very very good reason (i.e. not "$money$") for why those issues weren't actioned then they get fired. Every fucking one. Then promote a bunch of engineers.

Boeing used to be a great company when the engineers ran it. Now its shit because the MBAs in expensive suits run it.
