| Criterion |  Operations PDCA Cycle |  Product Discovery Test Card |  Operations Kaizen Event |
|---|---|---|---|
Purposedifferent | For an improvement that still has to prove itself in everyday work, the method runs it through small learning loops. It connects planning, checking, and standardization into a repeatable learning mode. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | For a tightly scoped process segment with noticeable waste, the method bundles shared energy for change. It suits situations that call for fast learning loops and visible adjustments. |
