The performance rating of project team members should primarily reference the agreed-upon key performance indicators (KPIs). KPIs are quantifiable measures that are established at the beginning of the project to evaluate the success of the project and the contribution of team members towards achieving project objectives.
This approach ensures that the assessment is objective and based on predefined criteria, rather than subjective opinions or inputs.
References: = The importance of using KPIs for performance assessments is supported by project management and business analysis standards, which advocate for measurable and objective criteria in evaluating team performance12.
