What is a common characteristic of a Sprint in Scrum?

A common characteristic of a Sprint in Scrum is that Sprints are time-boxed. This means that each Sprint has a fixed duration, typically lasting from one to four weeks, and this timeframe is established at the beginning of the project. The time-boxing of Sprints serves several important purposes: it creates a regular rhythm for the team, provides predictability, and helps to manage scope, as it encourages teams to focus on completing a set of well-defined work within the constraints of the Sprint length.

Time-boxing also encourages teams to prioritize their work and commit to delivering specific outcomes within that period. It fosters a consistent cadence for planning, review, and retrospective activities, allowing teams to evaluate their progress and adapt their processes over time. This focus on regular delivery and improvement aligns with the principles of agility, enhancing a team's responsiveness and effectiveness.

In contrast, the other characteristics presented do not align with Scrum principles. For example, indefinite lengths for Sprints would lead to unpredictability and a lack of structure, extensive documentation runs counter to the agile principle of valuing working software over comprehensive documentation, and allowing interruptions for urgent tasks contradicts the need for focus and commitment to the sprint goal, which can lead to lost productivity and unclear priorities.
