Most succession planning happens reactively — a key leader resigns, and suddenly HR is scrambling to figure out who could step in. A written succession plan flips that: it means the answer to "who's ready?" already exists before anyone asks the question.
Below is a simple, practical framework you can adapt, plus the template itself.
What Is Succession Planning?
Succession planning is the process of identifying critical roles in an organization, evaluating who could fill them if they became vacant, and preparing those people through targeted development — before the need becomes urgent.
It's not just for C-suite roles. Any role where a sudden vacancy would seriously disrupt the business — a lead engineer, a regional sales manager, a plant supervisor — is worth planning for.
Why Most Succession Plans Fail
Before the template, it's worth naming the common mistakes:
- Only planning for the CEO role. Mid-level critical roles cause just as much disruption when they're vacant, and they're far more likely to open up first.
- Treating it as a one-time exercise. A succession plan built once and never revisited is out of date within a year, as people change roles, leave, or grow.
- Keeping it entirely secret. Some confidentiality is reasonable, but high-potential employees who have no idea they're being considered for growth are more likely to leave for a company that tells them directly.
- No connection to actual performance data. Succession candidates should be identified using real review history and goal achievement — not just manager gut feeling.
The Succession Planning Process (5 Steps)
Step 1: Identify Critical Roles
Not every role needs a succession plan. Start with roles that meet at least one of these criteria:
- Significant business impact if vacant
- Specialized skills that take a long time to replace
- High historical turnover risk
Step 2: Define What "Ready" Looks Like
For each critical role, write down the specific skills, experience, and competencies required — before you start evaluating candidates against them. This keeps the process objective instead of based on who comes to mind first.
Step 3: Identify and Rate Potential Successors
For each critical role, list potential internal candidates and rate their readiness:
- Ready now — could step in within weeks
- Ready in 1–2 years — has the potential, needs specific development
- Ready in 3+ years — early-stage potential, longer runway needed
Step 4: Build Individual Development Plans
For every "ready in 1–2 years" or "3+ years" candidate, define the specific gap and the plan to close it — a stretch assignment, a mentorship, a training program, a lateral move for broader exposure.
Step 5: Review and Update Quarterly or Biannually
Succession plans go stale fast. Revisit ratings and development plans at least twice a year, and immediately after any major review cycle or organizational change.
Succession Planning Template
Use this structure for each critical role you track. You can build it in a spreadsheet, or — better — inside a system that already has performance and goal data connected, so readiness ratings aren't based on guesswork.
Start by naming the critical role itself and who currently holds it — for example, Regional Sales Manager, currently held by Jane D. Next, write down the business impact if the role were vacant, stated in concrete terms rather than a vague "high" or "low." For a Regional Sales Manager, that might mean the role oversees a pipeline worth several million dollars, so a gap here has an immediate revenue consequence, not just an operational one. Then list the key competencies required for the role — for this example, that would be team leadership, forecasting accuracy, and client relationship management — so any successor is evaluated against the same criteria, not a general impression of "doing well."
From there, list each potential successor individually, with three things noted for each: their readiness, their development gap, and the specific action being taken to close it. Ravi K., for instance, might be rated "ready in 1–2 years," with a noted gap in forecasting and budget ownership experience — the development action here could be assigning him to lead the next quarterly regional forecast under mentorship, giving him direct exposure to the skill he's missing. Meera S., by contrast, might already be rated "ready now," with no significant development gap — in her case, the useful action isn't closing a skill gap but broadening her exposure, such as cross-training on an adjacent region so she's prepared for a wider scope if the opportunity comes up sooner than expected.
Finally, record when the plan was last reviewed and when it's due for its next review — typically six months out. This last field matters more than it looks: a succession plan without a scheduled review date is the one that quietly goes stale, because there's no natural trigger to revisit it.
Repeat this same structure — role, incumbent, business impact, required competencies, successors with their readiness and development actions, and review dates — for every critical role you're tracking. Even a simple spreadsheet version of this is far better than no plan at all — but it works best when readiness ratings are tied to actual performance history, not just a single conversation.
Making Succession Planning Actually Stick
A template solves the "we have no process" problem. It doesn't solve the "nobody updates it" problem. To keep succession planning alive past the first quarter:
- Assign clear ownership — usually a mix of HR and the role's direct manager
- Set calendar reminders for the review dates, don't rely on memory
- Connect succession ratings to real review and goal data wherever possible, so they reflect actual performance trends rather than a single impression
- Revisit the plan immediately after any resignation on the team, not just on the scheduled date
This is where a standalone spreadsheet starts to show its limits — it doesn't update automatically when a candidate's performance changes, and it's easy for the "next review date" to quietly pass unnoticed. A talent management platform with succession planning built in keeps candidate readiness tied directly to live performance and goal data, so the plan reflects reality instead of a stale annual snapshot.
Conclusion
A spreadsheet template is a solid starting point for succession planning — but it's static by nature. It doesn't flag when a successor's performance shifts, doesn't remind anyone when a review date passes, and doesn't connect readiness ratings to actual review or goal data unless someone manually keeps it updated.
OfficePortal's Succession Planning & Talent Growth module solves the part templates can't: readiness ratings that stay tied to live performance history, development plans that connect directly to real review cycles, and a leadership pipeline that's visible to HR without a quarterly spreadsheet audit. If you're ready to move past a manual template, this is the next step. See how Succession Planning works inside OfficePortal.
