The basis for comments in evaluations should be:

Using concrete achievements and metrics as the basis for comments in evaluations ensures that the assessment is objective, demonstrable, and aligned with specific outcomes. This approach emphasizes tangible evidence of a person's performance, such as completion of projects, meeting deadlines, and the quality of work produced. Metrics provide a measurable standard that can be consistently applied, allowing for fair comparisons and clear accountability.

Moreover, focusing on concrete achievements can help to identify strengths and areas for improvement in a constructive manner, leading to more effective feedback. This method contrasts with relying solely on subjective experiences, which may vary widely from one evaluator to another and may not fairly represent a person's overall performance. Official high-level feedback may also lack the specificity needed for individual evaluations, while general observations may not capture the nuances of actual performance metrics. Thus, basing evaluations on concrete achievements offers a solid foundation for both the evaluator and the individual being assessed, promoting transparency and clarity in the evaluation process.
