When a project encounters a quality issue, such as an unacceptably high defect rate in early prototypes, the first step for the project manager should be to assemble a problem-solving team. This team should consist of quality assurance subject matter experts (SMEs) who have experience in this type of analysis. The team will then perform a cause-and-effect analysis to identify the root cause of the quality problem. Once the root cause is identified, the team can develop and implement a solution to address the issue, thereby improving the quality of the project deliverables.
