The Product Owner has the most recent and important information about the value and cost of the product being delivered. This information can greatly serve the team by allowing them to understand the product’s current state and how this affect where they will be going in terms of the vision of the product. If the Product Owner is able to carry this out then the team will have relevant information that will aid them in their decisions and execution of the product. If this is not carried out then the team will be in the dark – they will make poor decisions and struggle with the feedback given by the stakeholders since they have no transparency into the reality of the product.

The Scrum Team plans their work in the Sprint Planning meeting and that planned scope (Product Backlog Items) is meant to be respected… it is a commitment by the team. In exchange for that commitment, the rest of the organization commits to leaving the team alone to focus on its work. Focus and commitment are both important values of Scrum. Any interruption to any individual Team Member except the ScrumMaster and Product Owner is considered a cause for relieving the Team of its commitment. This rule of Scrum is designed to put pressure on the organization to leave the team to focus on the most valuable work. If the organization allows interruptions to the team’s work during the Sprint, then the team will not meet its commitments and this will diminish trust between the team and its stakeholders. That lack of trust will lead to onerous control mechanisms that reduce the team’s ability to self-organize which, in turn, will prevent the team from becoming a high-performance team.
