The adjustment is small. The history behind it isn’t.
During start-up of new equipment on an existing line, a stoppage keeps recurring. The supplier proposes another adjustment. Engineering wants to test it; Quality questions why earlier fixes failed; Production worries about the build plan.
Previous fixes have not held. Production doubts the supplier’s assurances, while the supplier feels its expertise is dismissed. Engineering is caught between restoring output and avoiding another temporary fix.
Explanations sound like excuses; questions like accusations. Frustrations are rehearsed within each group rather than discussed together. Suspicion grows, and the concerns behind it remain unresolved.
