Which activity is NOT part of a Sprint?

The activity of finalizing the project budget is not part of a Sprint because it typically falls outside the scope of the Scrum framework and its core activities. In Scrum, a Sprint is a time-boxed period where a defined set of work is undertaken to create a potentially releasable increment of the product.

The main activities that are part of a Sprint include planning the Sprint, which involves setting the Sprint Goal and selecting the Product Backlog items to work on; executing the Sprint, where the team collaborates to develop the increment; and conducting a Sprint Retrospective, in which the team reflects on the past Sprint to make improvements.

Finalizing the budget is generally a higher-level project management activity that occurs outside the daily operational focus of the Scrum Team and does not contribute to the immediate goals of delivering product increments within the Sprint timeframe.
