r tTurn defects into a sigma level, combine on time, undamaged and complete into perfect delivery, and see whether a bad day is a signal or noise.→ - Worksheet · 10 min5 WhysMove from a symptom to a root cause you can change, then agree one countermeasure, one owner and one check. Print it or save it as PDF.→

- Lean · 20 minTime StudyTime each element over five cycles with a stopwatch, space bar as the lap key. Get the standard time per station, takt from demand, a Yamazumi against it and the first element to move.→
- Lean · 30 minValue Stream MapMap one flow from supplier to customer with the pieces waiting between the steps. Get the lead-time ladder, PCE, takt and the bottleneck, then draw the future state and send its kaizen bursts to the Action Tracker.→
- Standard · 20 minStandard WorkOne job as a TWI breakdown: major steps, key points marked Safety, Quality, Technique or Cost, and a reason for each, with the time per step against the takt. Versions with change notes, print on A4, Word.→
