Final answer:
In the Scrum framework, creating a sprint backlog is part of the planning process that takes place during the Sprint Planning Meeting. Determining sprints for releases and daily task completion are not part of this planning stage, and demonstrating the product is part of the Sprint Review.
Step-by-step explanation:
The activities that form part of the planning process in the Scrum framework are crucial to ensuring the successful implementation and execution of projects using the Scrum methodology. Among the listed options, creating a sprint backlog is part of the planning process in Scrum. The sprint backlog is created during the Sprint Planning Meeting. This is where the team decides which items from the product backlog they will work on during the upcoming sprint, and how they will complete these tasks.
Option a, determining how many sprints will compose each release, might be considered a higher-level planning activity that often happens before sprints begin, but it is not part of the routine Scrum planning process. Option b, demonstrating the product during a sprint review meeting, is part of the Sprint Review which happens at the end of the sprint to inspect the increment and adapt the product backlog if needed. Option c, completing tasks each day during sprints, is part of the Daily Scrum and sprint execution rather than planning. Therefore, the correct answer is d, creating the sprint backlog.
