What to do NEXT
Option A, which suggests reviewing the change control process, is important but is not the primary concern in this situation. The issue is related to quality management, specifically the testing of components.
Quality Management Process Review: Given that the root cause of the issue is related to the quality of the product, it's crucial to review the quality management process. This involves examining how quality is planned, executed, and controlled throughout the project.
Process Audit: Performing a process audit as part of ongoing quality assurance allows the project manager to identify weaknesses or gaps in the quality management process. It helps ensure that processes are being followed as intended and that all necessary steps, including testing of components added via change requests, are included.
