Measuring an assistant's performance can feel awkward. Count tasks completed and you reward busywork. Measure nothing and you rely on gut feel, which tends to swing with your mood. The answer is a small set of role-specific measures focused on outcomes and quality — reviewed regularly and used for improvement, not surveillance.
This guide suggests KPIs for common assistant roles, how to set targets and how to use them well.
Principles for good assistant KPIs
- Measure outcomes, not activity. "Every external meeting has a brief" beats "number of briefs written."
- Keep it small. Four to six measures per role. More becomes noise.
- Make them observable. You or the assistant should be able to check each measure without a complex system.
- Set targets together. Agree targets in the first month based on what's realistic, then adjust.
- Review regularly. Monthly is usually right, with weekly spot checks in your check-in.
- Pair numbers with conversation. A number tells you something changed; a conversation tells you why.
We don't publish benchmark targets because they depend heavily on your context. The examples below describe what to measure; you set the numbers.
Executive assistant KPIs
- Calendar accuracy: count of errors per month — double-bookings, wrong time zones, missing video links, missing attendees.
- Meeting readiness: share of external meetings with a brief or agenda delivered before the meeting.
- Inbox responsiveness: whether items needing the leader are surfaced within an agreed window.
- Follow-through: share of action items from meetings followed up within an agreed time.
- Travel and expense timeliness: itineraries complete before departure; expense reports submitted by the deadline.
- Leader time saved (self-reported): the leader's monthly estimate of hours freed. Subjective, but useful.
Revenue or sales assistant KPIs
- CRM hygiene: share of open opportunities with a dated next step; duplicate rate; stale-stage count.
- List quality: bounce rate on researched contacts; share matching the ideal customer profile on spot check.
- Meetings booked: for roles that book meetings, count and show rate.
- Pipeline report timeliness: weekly pack delivered on time.
- Speed to lead: time from inbound lead to first response, where the assistant owns response.
See CRM hygiene checklist for how to define hygiene measures.
Operations assistant KPIs
- SOP coverage: number of key processes documented and current.
- Request turnaround: time from request received to completed, for routine request types.
- Checklist completion: recurring checklists (onboarding, offboarding, month-end tasks) completed on time.
- Vendor renewals: renewals reviewed before auto-renewal dates.
- Report timeliness: weekly operating reports delivered on schedule.
Customer support assistant KPIs
- First response time against your target.
- Resolution time for common ticket types.
- Customer satisfaction from your helpdesk's survey, if you run one.
- Quality score from a sample of tickets reviewed against a rubric (accuracy, tone, policy adherence).
- Escalation quality: escalations include all needed information.
Bookkeeper KPIs
- Close timeliness: books closed within your agreed number of days after month-end.
- Reconciliation completeness: all bank and card accounts reconciled each month.
- Uncategorized transactions: count remaining at close.
- Accuracy on review: adjustments required by your reviewer or CPA.
- AP/AR timeliness: bills prepared for payment before due dates; invoices sent on schedule.
Remember that ExecWing bookkeepers do not do tax work; your CPA owns tax preparation and advice.
Setting targets without micromanaging
In the first 30 days, don't set targets — gather a baseline. Then:
- Share the baseline with your assistant.
- Ask what they think is achievable and what would help.
- Agree targets for the next 60 days.
- Review monthly and adjust.
Targets set collaboratively are more realistic and more motivating than targets handed down.
A simple monthly scorecard
| Measure | Target | Month 1 | Month 2 | Month 3 |
|---|---|---|---|---|
Keep it in a shared doc. Discuss it in the first weekly check-in of each month.
What not to measure
- Keystrokes, mouse activity or screenshots. Activity monitoring tends to erode trust and measures the wrong thing. If you're tempted, it's usually a sign that outcomes aren't clearly defined.
- Hours logged as a performance measure. For a dedicated full-time role, hours are a given; focus on what's achieved.
- Vanity counts. Emails sent, tasks closed and similar counts rarely correlate with value.
When KPIs slip
A drop in a measure is a prompt for conversation, not a verdict. Common causes:
- Scope grew without priorities being adjusted.
- A tool or process changed.
- Instructions were unclear.
- The assistant is struggling and needs support or training.
Diagnose first. If an issue persists despite clear process and support, involve your provider; ExecWing includes weekly quality checks and back-fill.
Connecting KPIs to ROI
KPIs tell you whether the work is good. ROI tells you whether it's worth it. Pair them: alongside your role KPIs, track how you use the time you've freed. Our ROI scorecard shows how.
Example: a scorecard for a revenue assistant
Illustrative — targets are placeholders you'd set from your own baseline:
| Measure | How it's checked | Target |
|---|---|---|
| Open opportunities with a dated next step | CRM report, Monday | Set after month 1 |
| Duplicate contacts created this month | Dedupe tool report | Set after month 1 |
| Researched contacts that bounce | Sequencing tool report | Set after month 1 |
| Pipeline pack delivered by deadline | Calendar check | Every week |
| Inbound leads responded to within agreed window | CRM timestamp report | Set after month 1 |
Notice that each measure has a defined check. If a measure can't be checked without a debate, rewrite it until it can.
KPIs for specialist roles
For specialist roles, borrow measures from the function itself. A transaction coordinator might track deadlines met and compliance-file completeness at closing. A medical billing admin might track clean-claim submission and the age of open denials. An IT helpdesk technician might track first-contact resolution for runbook categories and escalation completeness. In each case, choose measures your team already uses to judge good work, then apply them to the assistant fairly.
Quick answers
Should KPIs affect pay? If you hire directly, that's your decision. With a managed service, use KPIs for feedback and quality conversations with your provider.
How often should targets change? Review quarterly. Raise targets when they're consistently met, and lower them if scope has grown.
Key takeaways
- Choose four to six outcome-focused measures per role.
- Gather a baseline before setting targets.
- Set targets together and review them monthly.
- Avoid activity monitoring; it measures the wrong things and erodes trust.
The bottom line
Choose four to six outcome-focused measures for the role, gather a baseline, set targets together and review monthly. Avoid activity surveillance. Used well, KPIs make expectations clear and give your assistant a fair way to show their impact.
