|---|---|---|---|
Purposedifferent | When a team wants to deliberately adjust its working behavior, it makes habits visible and assessable. It focuses on concrete changes instead of diffuse mood. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | When improvement options need to be sorted more finely than just start and stop, it brings observations into clear kinds of action. This makes visible what should be done more, less, newly, or continued. |
