What is key person risk and how does documentation mitigate it?
Key person risk is the business vulnerability created when critical knowledge, skills, or relationships are concentrated in a single employee. If that person leaves, gets sick, or goes on vacation, the team cannot perform essential functions. Documentation mitigates this by externalizing that knowledge into written processes that anyone can follow.
How do you identify key person risk in your organization?
Key person risk often hides in plain sight. Look for these signals:
- Only one person can run a specific report, deploy code, or handle a vendor relationship
- Recurring questions always route to the same team member
- Vacation anxiety — the team dreads when a specific person is out
- No documentation exists for processes that person owns
- Onboarding blockers — new hires cannot learn certain tasks without that person's direct involvement
A simple audit: ask each team member to list every process only they know how to do. The combined list is your key person risk map.
What is the most effective way to reduce key person risk?
The fix is systematic documentation combined with cross-training. Neither works alone — documentation without practice creates shelf-ware, and cross-training without documentation creates another single point of failure.
| Action | Purpose |
|---|---|
| Document critical workflows | Capture step-by-step instructions with screenshots and context |
| Cross-train a backup | Have a second person perform each critical task at least monthly |
| Record screen workflows | Use Glyde to capture processes with annotated screenshots and contextual descriptions as they happen |
| Maintain a responsibility matrix | Map every critical task to a primary and backup owner |
| Schedule quarterly reviews | Verify documentation is current and backup personnel are still capable |
Start with the highest-risk processes — the ones that would cause the most damage if the key person disappeared tomorrow. Even documenting your top five critical workflows significantly reduces organizational risk.
