Three months into a chief of staff engagement, most founders judge it on a gut feeling. That's not wrong exactly, but a gut feeling can't tell you whether to fix the scope or end it. Here are the signals that actually carry information, and the ones that just sound like they do.
The signal that matters most: what you stopped doing
Not what got added to your plate, what came off it. Specifically: which meetings you no longer sit in because someone you trust is capturing them, which reports you no longer build yourself, which follow-up emails you no longer send because they were already sent. If you can't name at least three concrete things, in detail, that used to be yours and aren't anymore, the role hasn't actually changed your week yet, whatever else is happening around it.
The tracker test
Open the initiative tracker cold, with no warning, and ask yourself if you know the real status of your top three priorities without asking anyone. If the answer is yes, the system is running. If you still have to ping someone to find out, the tracker is decoration, not infrastructure, no matter how good it looks.
The follow-through rate
Look back at the last leadership meeting. Of everything that got decided, what fraction actually happened by the date that was named? Above roughly 80% is healthy. Below that consistently, over several cycles, is a real problem worth naming directly, not a run of bad luck. This single number tells you more about whether the cadence is working than almost anything else you could ask.
What doesn't mean anything
- "They feel busy." Busy is not the same as effective. A calendar full of meetings can coexist with nothing actually closing.
- "They're in everything." Presence isn't the job. A chief of staff who attends every meeting as a silent observer is expensive decoration, not leverage.
- "The team likes them." Worth having, not worth mistaking for the actual measure. Plenty of well-liked hires still aren't moving anything.
The 90-day gut check, made concrete
Instead of "is this working," ask four specific questions: What came off my plate that I can name? Can I read the tracker without asking anyone to explain it? What closed end to end this quarter, not just started? Would I notice immediately if this stopped tomorrow? If the honest answer to that last one is no, that's the real signal, more than any of the softer ones above.
If these signals aren't showing up and you're not sure whether the fix is scope or the fit itself, that's exactly the kind of thing worth a direct conversation rather than another quiet quarter.
