A mature Scrum Team is expected to continuously improve their quality standards and deliver potentially releasable Increments of value that meet the Definition of Done12.The Definition of Done is a shared understanding of what it means to complete a Product Backlog item, and it may vary from one Scrum Team to another3. As the Scrum Team matures, they may expand their Definition of Done to include more rigorous criteria, such as higher levels of testing, documentation, performance, security, usability, etc .This way, they ensure that their product Increment is always ready for release and meets the expectations of the stakeholders and customers12.

According to the Scrum Guide 2020, the entire Scrum Team is accountable for creating a valuable, useful Increment every Sprint1234. This includes the Developers, the Product Owner, and the Scrum Master4. The Developers are committed to creating any aspect of a usable Increment each Sprint12, while the Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team12. The Scrum Master fosters an environment where the Scrum Team can work effectively1.

. If a stakeholder is unhappy with the quality of the product, the Scrum Master can coach the Product Owner on how to effectively communicate this concern to the Developers1. The Scrum Master can also encourage the Product Owner to put quality specifications on the Product Backlog1. This allows the Developers to understand the stakeholder's expectations and work towards meeting them1. The Developers are responsible for building quality into the product, but the stakeholders (through the Product Owner) are responsible for setting what is expected in terms of product and process quality1.

If the Scrum Team cannot complete its work by the end of the Sprint, the Sprint does not get extended. Instead, the unfinished Sprint Backlog Items go back to the Product Backlog and can be addressed in the following Sprint12. This approach allows the team to get better at estimating and reduces complexity due to the consistency of the Scrum Events2. The Scrum Team continuously learns and adapts12.

The two primary ways a Scrum Master helps a Scrum Team work at its highest level of productivity are by facilitating Scrum Team decisions and by removing impediments that hinder the Scrum Team12. The Scrum Master is a facilitator and a coach, helping the team remove impediments and facilitating team decisions12. This enables the team to focus on their work and maintain their productivity12.

According to Scrum.org, the Developers who will be doing the work are responsible for the sizing of Product Backlog items1. The Product Owner may influence the Developers by helping them understand and select trade-offs1. This implies that the Developers size the items after clarifying requirements with the Product Owner1.
