Performance rarely drops randomly.
There’s almost always a trigger — a shift change, a process update, a change in equipment, a change in team composition, a change at home. If you can identify what changed around the time the issue started, you can usually identify what category the problem lives in. The trigger is the clue.
Take Action: Identify when a current performance issue started. Then write down everything that changed in the operation, the team, or the person’s circumstances around that time. The trigger is almost always in that list.
