Which performance appraisal method is an effective tool when teamwork and participation are part of the organizational culture?

Self-appraisal relies on individuals assessing their own performance, which can lead to biased evaluations and does not necessarily encourage collaboration or participation from team members. While it promotes self-reflection, it lacks the collective input essential for organizations emphasizing teamwork and shared goals.

Appraisal by subordinates focuses on how well a manager or supervisor is performing from the perspective of their direct reports. This method is useful for understanding leadership effectiveness, but it may not capture the collaborative efforts and contributions of team members in a way that supports a team-based culture.

Appraisal by customers evaluates performance based on customer satisfaction and feedback. Although important for service-related roles, this approach does not directly assess teamwork or participation among employees, making it less effective in organizations prioritizing collaborative efforts internally.
