What are good key performance indicators (KPIs) for a chief of staff?

Two immediately came to mind:

1. Look at the CEO’s calendar after one year on the job. Has the calendar shifted, nearly exclusively, to things ONLY the CEO should be doing? Have tasks the CEO could be doing, but shouldn’t, been removed?
2. The transition from tasks the CEO could do (but shouldn’t) to tasks only the CEO should do must be stark and significant. Otherwise, the chief of staff has not effectively created capacity, prioritized how the CEO spends their time, and pushed work out into the organization. Put simply, a chief of staff must be a capacity creator for the CEO, and this KPI is one way to track it.
3. Measure the job satisfaction rate of the C-Suite executives after a chief of staff’s first year. A great chief of staff creates value not just for the CEO, but also for the broader executive team and the organization at large.
4. The chief of staff:
5. • Directs traffic to reduce overlap among projects and people.
   • Helps clarify what the CEO wants done when there’s confusion or uncertainty.
   • Determines the right times to approach the CEO about an issue.
   • Rolls up their sleeves to assist C-suite colleagues when needed.

If a chief of staff does their job well, a positive result will be a happier, more productive C-suite.
