The ART predictability measure is a critical metric within the SAFe framework. It is important because it enables businesses and other stakeholders to plan effectively. This measure provides insights into how reliably teams and ARTs can deliver business value against their planned objectives. By understanding the predictability of the ART, stakeholders can make informed decisions about future investments, resource allocation, and market commitments. It is not primarily about identifying under-performing teams (A), fixing the scope at the beginning of the PI (B), or indicating when the Solution is ready to be released ©. Instead, predictability measures provide a fact-based understanding of the ART’s ability to deliver on its commitments, which is essential for effective planning and adjustment of strategies1.QUESTION NO: 91
Why is it important for the Release Train Engineer (RTE) to understand Tuckman's group dynamic
stages?
A.Tuckman helps RTEs to better understand Team and ART topologies
B.An ART is a team of teams and will likely progress through the Tuckman stages
C.The Tuckman four stages should be reflected in the design of the ART Kanban
D.The Tuckman dynamic nature of the stages requires that we assume variability and preserve options
Answer: B
Understanding Tuckman’s group dynamic stages is important for a Release Train Engineer (RTE) because an Agile Release Train (ART) is essentially a team of teams, and like any team, it is likely to progress through Tuckman’s stages of group development: forming, storming, norming, and performing1.
Here’s a detailed explanation of how each stage applies to an ART:
•Forming: In this initial stage, teams come together and start to understand their objectives and boundaries. The RTE plays a vital role in guiding the ART through this stage by helping establish the vision, mission, and objectives of the train.
•Storming: As teams begin working together, they may encounter conflicts and challenges. The RTE can help navigate these by facilitating communication and conflict resolution, ensuring that all teams are aligned and focused on the ART’s goals.
•Norming: During this stage, teams start to resolve their differences, establish processes, and begin to work more effectively together. The RTE supports this by fostering a culture of collaboration and continuous improvement.
•Performing: In the final stage, teams operate efficiently and effectively toward achieving the ART’s goals. The RTE’s role here is to ensure that this high performance is sustained and that the teams continue to innovate and improve.
By understanding these stages, the RTE can better facilitate the ART’s journey through them, helping to ensure that the teams within the ART collaborate effectively, resolve conflicts, and ultimately deliver value more predictably. This understanding also helps the RTE to anticipate the challenges that may arise at each stage and to be better prepared to support the ART in navigating them. The knowledge of Tuckman’s model equips the RTE with the insights needed to lead the ART through its developmental journey, contributing to the overall success of the train.
