According to project management best practices, one of the key elements of successful project implementation is to manage the risks and avoid scope creep12. If there are high-priority issues that require external domain expertise, the project manager should not ignore them, ask the issue reporter to close them, or reduce the project scope. These actions could compromise the quality and value of the project deliverables, and lead to customer dissatisfaction and potential litigation.
Instead, the project manager should review the open issues with the issue reporter and assess the impact and urgency of each issue. Then, the project manager should issue a change request to hire an external domain expert who can help resolve the issues and ensure the project meets the requirements and expectations of the stakeholders. This way, the project manager can maintain the project scope and quality, and manage the risks effectively34.
