When establishing the Sprint length, two important factors to consider are the level of uncertainty over the technology to be used and the risk of being disconnected from the stakeholders. The level of uncertainty over the technology impacts how much time the team will need for exploration and experimentation before they can deliver a valuable product increment. If the technology is well understood, shorter sprints might be adequate, but if there is a lot of uncertainty, longer sprints may be necessary. The risk of being disconnected from stakeholders also needs to be considered because shorter sprints enable more frequent review and feedback from stakeholders, ensuring that the product development stays aligned with their expectations and needs.
