Which of these phases are used in a free format Timebox?

In the context of agile methodologies, a free format Timebox is often associated with an unstructured approach to limit activities within a specified timeframe while allowing flexibility in how those activities are executed. Iterative development is a fundamental aspect of this approach, as it emphasizes continuous refinement, adaptation, and improvement over multiple iterations.

During iterative development, teams work on small, consumable increments of a product, completing cycles of planning, executing, reviewing, and adjusting. Each iteration enables teams to respond to feedback and evolving requirements dynamically, making it a fitting element of a free format Timebox.

While other phases such as refinement, investigation, and consolidation might be relevant in certain agile contexts, they typically do not align with the primary focus of a free format Timebox, which centers around iterative development and the ongoing evolution of project outputs. Each specific phase may have its role in different frameworks or methodologies, but the core of the free format Timebox is best represented by the iterative nature of development that embraces change and continual delivery of value.
