According to the PMBOK guide, the definition of done (DoD) is a clear and concise list of requirements that a deliverable must adhere to for the team to consider it complete1. The DoD helps to ensure that the customer’s expectations are met and that the quality standards are maintained2. The PMI-PBA guide also states that the business analyst should collaborate with the customer and the team to define and validate the acceptance criteria for each feature3. Therefore, the best way for the project manager to avoid the situation of features being rejected by the customer is to ensure that the DoD is well defined and complete for future iterations, and that it aligns with the customer’s needs and preferences. References:
