Case Study
N+I 7-Day Delivery Rhythm Case
Applied an N=6 and I=1 rhythm model to build standardized production cadence and weekly capacity planning.
Background
The client faced order fluctuation, complex cross-process coordination, and long delivery cycles.
Actions
- Split the full cycle into N+I target management.
- Reorganized winding, press forming, assembly, drying, final assembly, and testing into 6 beats.
- Built supporting scheduling, staffing, and process monitoring mechanisms.
Results
- Established a 7-day total-cycle methodology (N=6, I=1).
- Formed a rhythm-based model of 24 units/day and 120 units/week.
