A. The stakeholders have not been using the Sprint Reviews to actively engage, and inspect and evaluate progress. This is a possible factor that may have led to the disappointment and anger of the stakeholders. The Sprint Review is an event where the Scrum Team and the stakeholders collaborate to inspect the product Increment and adapt the Product Backlog based on feedback and new insights. If the stakeholders do not participate actively in the Sprint Review, they may miss the opportunity to provide input, voice their concerns, and influence the direction of the product development.
D. The Scrum Master has not ensured transparency. This is another possible factor that may have led to the disappointment and anger of the stakeholders. The Scrum Master is accountable for establishing and promoting transparency among the Scrum Team and the stakeholders, by ensuring that everyone has a clear and common understanding of the product vision, the Product Goal, the Product Backlog, the Sprint Goal, the Sprint Backlog, and the Definition of Done. Without transparency, there may be misalignment, confusion, or unrealistic expectations among the stakeholders regarding the product being built.
E. The Product Owner has not been interacting frequently with the stakeholders and kept them aware of the progress of the project. This is also a possible factor that may have led to the disappointment and anger of the stakeholders. The Product Owner is responsible for engaging with the stakeholders regularly and communicating the value, scope, and status of the product development. The Product Owner should also seek feedback from the stakeholders and incorporate it into the Product Backlog refinement and ordering. If the Product Owner does not interact frequently with the stakeholders, they may feel disconnected, ignored, or dissatisfied with the product being built.
