During a management review in the execution phase of a project, it is most effective to review metrics and key performance indicators (KPIs) that objectively reflect the status of the project deliverables. This data-driven approach provides a clear and quantifiable assessment of how the project is performing against its planned objectives. It allows for an accurate understanding of the project's progress and highlights areas that may require attention or improvement.
