The project manager should analyze the reason for the gap in understanding with both sides and negotiate a solution, as this is a strategy for managing stakeholder dissatisfaction in agile projects. According to the Agile Alliance, one of the principles of agile software development is to satisfy the customer through early and continuous delivery of valuable software. However, sometimes the customer or stakeholder may not be satisfied with the product, even if it meets the acceptance criteria and is approved by them. This may happen due to various reasons, such as unclear or changing requirements, miscommunication, unrealistic expectations, or lack of feedback. The project manager should identify the root cause of the dissatisfaction and try to resolve it through dialogue and collaboration. The project manager should also use agile techniques, such as backlog refinement, user stories, sprint reviews, and retrospectives, to ensure that the product delivers value to the stakeholder and aligns with their vision and goals1.
The other options, asking the project team to perform the modifications, asking the stakeholder to submit a change request, or explaining to the stakeholder that the project can be closed, are not the best ways to manage stakeholder dissatisfaction in agile projects. Asking the project team to perform the modifications may not address the underlying issue of the dissatisfaction and may also introduce new risks or defects to the product. Asking the stakeholder to submit a change request may not be feasible or appropriate in an agile environment, where changes are expected and welcomed, as long as they add value to the product and do not compromise the quality or scope2. Explaining to the stakeholder that the project can be closed may not satisfy the stakeholder or improve the relationship, as it may imply that the project manager is not willing to listen to their feedback or concerns.
