A sprint is a feedback container
In Scrum, a sprint is a fixed-length period in which the team works toward a sprint goal and creates a usable increment. The official Scrum Guide defines the accountabilities, events and artifacts that make up Scrum.
01Sprint goal
02Select work
03Build & test
04Daily coordination
05Review increment
06Retrospective
Planning is not a promise to the future
A sprint plan should create a credible path toward the goal. It should not encourage teams to hide uncertainty simply to make a commitment look precise.
Incremental delivery
Delivering smaller slices makes feedback cheaper. If a customer dislikes a direction after six months, the cost of discovering that is high. If the customer sees a usable slice after two weeks, the team can adjust earlier.
