Charlene comes from left field with "I have a problem with all of that. Why do we do that? Why do we try to protect the performance of each work center? I thought that we already agreed that local efficiencies don't count." Somehow these sentences sound familiar to me. Then I recall that Ruth's complaint was "We try to protect the performance of each step." I also recall what Ruth said next. "We put in so much safety, and the project as a whole is still exposed." Does it mean here that the performance of the assembly line is exposed? Of course.
