|---|---|---|---|---|
Purposedifferent | When a sprint is over and friction shouldn't simply be carried forward, it opens the view onto collaboration and patterns. It creates space to see causes and changes together. | When a team wants to read momentum, brakes, and risks together, it offers an easily understandable picture of the situation. It makes drive, obstacles, and headwind visible in the same picture. | 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. | When growth ideas surface quickly, the temptation to build immediately instead of learning is high. A Growth Experiment frames an assumption so target group, lever, and measurement are clear before the first deployment. |
