Definition:

Iteration Execution is how Agile Teams manage their work throughout the Iteration timebox, resulting in a high-quality, working, tested system increment. Developing high-quality systems is a challenge for every Agile team, Agile Release Train (ART), and Solution Train. No matter the preparation, no matter the planning, without effective iteration execution, scaling is nearly impossible, and solution quality is compromised. During the iteration, each team collaborates to define, build, and test the Stories discussed and selected in the course of Iteration Planning. They track the iteration’s progress and improve the flow of value by using story and Kanban boards and Daily Stand-up (DSU) meetings. They deliver stories throughout the iteration and avoid ‘waterfalling’ the timebox. They apply Built-In Quality practices to build the system right. These completed stories are demoed throughout the iteration and at the Iteration Review. During the Iteration Retrospective, the Agile team reflects on their practices and challenges and makes small improvements every increment. They work effectively with other teams on the train and participate in the System Demo.
