A bad onboarding wastes the first quarter. A good one means the EA is running the calendar solo by day 15. Our EA onboarding duration benchmarks put concrete week-by-week numbers behind the phasing below.

Week 1: Shadow and listen

Have the EA shadow every meeting, not to participate, but to map the stakeholder landscape. Who gets a response within one hour? Who can wait? They should leave week one with a written stakeholder map. Our guide on stakeholder management for executives covers the triage and continuity work that stakeholder map is meant to enable.

Provide read access to the last 90 days of email threads. Do not filter it. The EA needs to see real triage decisions, not a sanitized sample.

Hand over one low-stakes calendar block to manage end-to-end. A recurring team standup is ideal. Debrief on Friday.

Week 2: Take the inbox

Transfer inbox management on day eight. Keep a shared inbox view for the first week of dual access, so you will see every decision the EA makes in real time.

Set a daily 10-minute debrief at end of day. Agree on a flag protocol: what earns a Slack ping versus what goes into the end-of-day summary.

Review and agree on the draft reply tone guide. This is not optional. One off-brand email to a board member undoes a month of trust.

Week 3: Own the calendar

By day 15, the EA should be accepting, declining, and rescheduling without asking first, within a written decision framework you agreed in week 2.

Schedule a mid-point review. Walk through the stakeholder map together. Update it. Agree on the three things the EA will own solo before day 30.

Day 30: Accountability sign-off

Run a written 30-day review. Score the EA on: inbox response speed, calendar conflicts, stakeholder escalations caught or missed, and tone consistency. If this hire has surfaced gaps you did not anticipate at the sourcing stage, revisit the process in how to hire an executive assistant.

Set 90-day OKRs. The EA should have at least two measurable outcomes they own, not tasks they assist with.

Book a monthly one-on-one. EAs who get regular feedback stay longer and perform better.
