When deliverables do not meet requirements, it is essential to understand the root cause of the issue. The first step should be to engage with the project team to discuss the processes used and identify any misunderstandings or gaps in knowledge. This approach aligns with the PMBOKGuide's emphasis on communication and stakeholder engagement as key aspects of project management. It also reflects the principles of collaboration and continuous improvement found in business analysis practices. : = PMBOKGuide1, PMI Professional in Business Analysis (PMI-PBA) reference materials2.
