During the executing phase, a project manager is reviewing the issue log and finds there are outstanding high-priority issues that are still open. Most of the open issues require effort from external domain experts who are not on the project team.What should the project manager do?

This option is unrealistic, as expecting team members to rapidly acquire new domain knowledge may lead to delays and could compromise the quality of the project's deliverables. It is often impractical for team members to become proficient in a new area under time constraints, especially when specialized expertise is required.

Reducing the project scope can be detrimental and may not address the high-priority issues effectively. This approach could lead to incomplete project deliverables or dissatisfaction among stakeholders who expect a full-featured product. It is better to seek the necessary expertise to resolve issues rather than compromise on project outcomes.

This option fails to address the underlying problems and would leave critical issues unresolved. Simply closing issues without resolution can lead to larger problems down the line and damage project credibility. It's essential to seek solutions rather than dismiss concerns.
