Step-by-step explanation:
Features in agile project management are typically sized or split to fit within a Sprint. A Sprint is a set time period during which specific work has to be completed and made ready for review. It is part of the Scrum framework, which is an agile development methodology. The duration of a Sprint is usually between one to four weeks, depending on the team's workflow and the nature of the project. This regular, repeatable work cycle, also known as an iteration, is structured so that the team can work on and complete set features or user stories within this duration.
