Back upstream to the source of the problem, too much rework was already being required by the time the components got to the Boeing assembly plant (i.e. the Spirit techs onsite doing repairs). In an environment where process exceptions are the norm, people begin to deprioritize handling exceptions properly. Everything can't be critical or emergency all the time. And once that deprioritization happens, safety critical process exceptions begin being treated like all other exceptions. Because they're all exceptions, and there are so many. And eventually normalization of out of bounds situations via repeated team exposure leads to catastrophe. NASA lost two shuttles via the same organizational problem.
