The evaluation system shapes motivation: reflections on organizational justice

In many performance appraisal processes, the way scores or ratings are distributed directly affects people’s motivation and their perception of fairness.
When evaluation systems use only three categories, many professionals end up stuck in a broad category like “average.” This ambiguity can demotivate even the most committed ones. I have seen this happen in corporate assessments: talented and hardworking professionals feel discouraged when they see no distinction between their performance and that of colleagues who are clearly less engaged, all because of a metric that fails to capture nuance.
On the other hand, more segmented systems (with five categories, for example) provide small steps to climb. And it is precisely this possibility of “small victories” that seems to fuel motivation. This echoes what I often observe in practice: when an employee sees that they are close to reaching the next level, they tend to engage more. The concrete hope of progress has a mobilizing power that a generic system, where everyone is lumped under the same label, simply does not have.
Moreover, the perception of organizational justice is greater in a broader measurement system. It can even “protect” some employees’ self-esteem by placing them in the same performance group as stronger colleagues. However, it can also generate frustration for those who are actually excelling but do not receive proportional recognition. This kind of invisibility is dangerous: it erodes the sense of merit and pushes the most talented either into discouragement or out of the company.
This makes me reflect on the responsibility that leaders and HR professionals carry when choosing evaluation systems. The way we evaluate is not neutral: it shapes behaviors, impacts emotions, and defines career paths. When we use generic categories out of convenience or tradition, we may be stifling the potential of many. That’s why, rather than seeking systems that are simply “easy to apply,” we need metrics that are fair, motivating, and respectful of each employee’s individuality.
The categorization of measurement levels in a performance appraisal matters — not only as an assessment structure but also as a clear signal of how willing we are to see people in greater depth. After all, each additional level in an evaluation system can also serve as a step toward recognition, encouragement, and justice.
