Before the workshop, the team members should read and identify relevant user stories from the product backlog that directly contribute to the goal of developing the feature for receiving and resolving customer complaints. This ensures that the stories being worked on are well-understood and aligned with the release goal.
The team should also consider the possible risks associated with each selected user story, such as technical challenges or dependencies. Additionally, they should evaluate the value each story adds to the final user (customer), ensuring that the team focuses on delivering maximum value in the release.

When the team is not confident that the solution will work, delivering the minimum marketable feature (MMF) to customers for feedback is the best approach. The MMF represents the smallest, functional version of the product that can provide value to customers. By delivering this early and obtaining feedback, the team can validate assumptions, identify potential issues, and make necessary adjustments before committing to further development. This approach allows for early course correction and ensures the solution aligns with customer expectations and business needs.
