A team member identified a defect in the initial solution design and stakeholders are unsure whether to deploy the system. What should the project manager do?

The project manager should perform a risk analysis against the identified defect. This involves assessing the probability of the defect occurring (or its current existence) and its potential impact on project objectives, scope, schedule, cost, and quality. This analysis provides stakeholders with the necessary information to make an informed decision about whether to proceed with deployment, redesign, or implement other solutions. Proposing redesigning the solution is premature without understanding the full implications of the defect. Revising quality control measurements doesn't address the immediate defect or its impact. Developing a mitigation plan based on the solution design is a potential outcome of the risk analysis, but the analysis itself must precede the development of specific responses.
