In the context of PMO (Project Management Office) functions, performance indicators serve as critical tools to measure the effectiveness and success of the PMO's activities. The best practice is to usetwo to four performance indicators per functionduring each evaluation cycle. This ensures that the evaluation is comprehensive enough to provide valuable insights without creating unnecessary bureaucracy or excessive control, which can hinder flexibility and innovation.

A balanced number of indicators allows organizations to monitor the essential aspects of each function while maintaining efficiency and adaptability. By focusing on 2-4 indicators, PMOs can achieve a manageable level of control without overwhelming the team with too much data or analysis, which can be counterproductive. This approach aligns with the principle oftailoring and agilityin project management, where processes and metrics should be adapted to fit the context of the work, providing maximum benefit with the least effort.

This recommendation is derived from thePMBOK Guideand related frameworks likeRicardo Vargas' PMO methodologies, which emphasize focusing on value, minimizing waste, and maintaining a lean and effective governance structure​​​.
