How often should well-defined PI objectives be reviewed during each iteration?

Well-defined Program Increment (PI) objectives are typically reviewed at the end of the PI, which serves as a crucial point in the Agile framework for assessing progress and alignment with goals. During this review, teams can evaluate whether they have achieved the objectives they set out to accomplish, facilitating discussions on improvements and adjustments for the next PI.

Reviewing PI objectives at the end of the increment also helps in identifying any challenges faced during the execution and provides a data-driven basis for planning future iterations. By focusing on this review period, teams can ensure that any feedback and learnings are captured effectively, which is vital for continuous improvement and alignment with strategic goals moving forward.

In contrast, options such as reviewing weekly or during each Scrum meeting might not allow enough time for meaningful evaluation of performance against longer-term objectives. Similarly, a mid-iteration review may not provide a comprehensive overview of objectives as set for the entire Program Increment. The end-of-PI review period ensures a broader context and allows for a thorough assessment of progress and alignment with overall product strategy.
