Now compare how often engineers release bad parts, which is probably daily, to how often unions go on strike. Anymore the latter is zero because they gave up strikes in their collective bargaining agreement. Even if they didn't, they still only went on strike once a decade or so.

Having said all that, I am still a fan JIT. When an engineer released a bad part prior to JIT there were often semi loads of parts that needed to be scrapped or reworked. With JIT problems can be caught and fixed before they become enormous.

I'm not a big fan of six sigma, however.

Okay, maybe my Union comment was a little over the top…

But I do feel you may be misplaced to blame engineers and there changes. You’re more likely to see disruptions from things like, a fire, Tornado or a business going under.

Building cars all your changes are coming before home line tryout and vehicle launch… This is where Proto-Type meets Production and changes are made in order to support these realities… Rule number one production rules.

Once in production you rarely see engineering changes that effect production. What usually occurs are issues relating to tool ware or customers TGW’s that may force a tooling change.
