The length of a Sprint should be: (choose the best answer)

The length of a Sprint is the timebox within which the Scrum Team creates a potentially releasable product Increment. The Sprint is a container for all the other Scrum events, such as the Sprint Planning, the Daily Scrum, the Sprint Review, and the Sprint Retrospective. The Sprint is also a feedback loop that allows the Scrum Team and the stakeholders to inspect and adapt the product and the process.

The length of a Sprint should be no more than one calendar month. This is the maximum duration allowed by Scrum, as longer Sprints can increase the complexity and risk of the product development. Longer Sprints can also reduce the agility and responsiveness of the Scrum Team to changing customer needs and market conditions.

The length of a Sprint should also be short enough to keep the business risk acceptable to the Product Owner. The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. The Product Owner is responsible for managing and refining the Product Backlog, collaborating with the stakeholders and the Developers, and ordering the items in a way that best achieves goals and missions. The Product Owner represents the interests of everyone with a stake in the product and ensures that the Scrum Team works on the right things at the right time. The length of a Sprint affects how frequently and effectively the Product Owner can validate, verify, and deliver value to the customers and users.

The length of a Sprint should also be short enough to be able to synchronize the development work with other business events. The Scrum Team operates within a broader organizational context that may have other events, cycles, or deadlines that affect or depend on product development. For example, there may be marketing campaigns, sales promotions, regulatory compliance, or contractual obligations that require coordination and alignment with the product delivery. The length of a Sprint affects how well and timely the Scrum Team can synchronize their work with these other business events.
