The Chief of Staff (CoS) is often evaluated based on a combination of quantitative and qualitative KPIs. Common key metrics include the implementation rate of strategic initiatives, the number of delivered projects, improved communication between management and operations, and management and CEO satisfaction. Other important KPIs are employee engagement, speed of decision-making, and the ability to break down silos. The evaluation should include feedback from multiple stakeholders – the CEO, management team, and project team – to get a holistic view. It is also common to use dashboards and status reports to monitor ongoing initiatives. The KPIs must be aligned with the organization’s strategy and the CoS’s specific mandate.
