Succession plans
Every critical role gets a one-page plan. The plan answers what happens on the day the incumbent leaves.
The four layers
| Layer | Window | Question |
|---|---|---|
| Interim cover | Days 0 to 30 | Who keeps the role running if the incumbent leaves without notice? |
| Short-term backfill | Days 30 to 90 | Who can perform the role with support while a permanent decision is made? |
| Permanent successor | Named | Who is being developed for the role, by when, and through what? |
| External-hire trigger | Condition | Under what conditions do we hire outside instead of promoting? |
External-hire triggers. Hire externally when no internal candidate will be ready within the time the business can wait, when the role's next stage requires a capability nobody inside has built, or when the internal candidate's readiness depends on assumptions not yet tested.
The trigger raises the evidence standard; it never lowers it. See "Readiness for external candidates" below.
Developing successors
A successor without a development plan is a name on a slide. Readiness comes from doing the work, not from courses about it.
Build breadth deliberately. The strongest successors often have diagonal careers, not vertical ones: real assignments across sales, customer service, finance, operations, risk, legal, people, technology, and partners. Breadth produces situational fluency. A leader who knows how other functions think sees more of the system, judges better, and decides faster.
Widen the pool. Do not treat commercial and support talent as separate populations. Everyone contributes to the customer outcome, and a leader from finance, risk, or operations who understands that outcome may be the strongest successor for a commercial role. Give the pool a shared question: how does your work contribute to what the customer and the company are trying to achieve?
| Development action | What it tests or builds |
|---|---|
| Acting or cover assignment | The role's real demands, under real conditions |
| Stretch project tied to a role outcome | Whether they can produce the outcome, not just describe it |
| Leading the incumbent's team meeting or forecast review | Operating altitude and composure |
| Exposure to the incumbent's peers and key customers | Cross-functional standing and relationship transfer |
| A mentor one level above the target role | Perspective on the role's next stage |
Each successor gets at least one action per quarter, with a date and an observer who reports what they saw.
Measuring the bench in three tiers
| Tier | Question | Measures |
|---|---|---|
| Activity | Are we doing the work? | Critical roles with a written plan; successors with a dated development action; single points of failure with knowledge captured |
| Leading | Is the bench getting stronger? | Bench score; share of critical roles with a ready-now successor; successor readiness moving forward; second contacts in place on top accounts |
| Outcome | Did it work when it mattered? | Internal fill rate for critical roles; time to fill; performance through the transition; regrettable attrition among top performers |
Cadence
| When | What |
|---|---|
| Quarterly | Re-score the bench; update readiness; run the talent review |
| Within 30 days of any critical departure | Activate the plan; review what the plan got right and wrong |
| Annually | Re-test which roles are critical as the business changes |
Readiness for external candidates
Past performance is evidence of capability in a context. Succession needs evidence of capability in this context, or convincing evidence that the leader can adapt to it.
A track record is produced by the leader, the team, the operating system, the market, the company stage, and the culture together. Change enough of those and prior performance becomes evidence, not a guarantee.
Never mark an external candidate ready now from title and scale alone. Require evidence on four dimensions:
| Dimension | Question |
|---|---|
| Comparable work | Have they performed the critical work this role requires, not just led people who did? |
| Operating-context fit | Have they succeeded under similar pace, ambiguity, management cadence, and decision rights? |
| Adaptability | Have they abandoned a previously successful behavior when the environment changed? |
| Multiplier fit | Does the way they develop and deploy leaders match what this organization needs? |
A gap on operating-context fit or adaptability blocks a ready-now call, however impressive the résumé.
Deconstruct the track record.
- What produced the past results: the organization they inherited, the talent, the brand, the market position, the authority, the stability?
- How different is this environment: stage, growth rate, sales motion, decision rights, cadence, maturity, customers, product, culture?
- What will they have to unlearn? Ask for a time the practices that made them successful stopped working, and what they changed.
- What evidence shows adaptability? "I am highly adaptable" is not evidence. Which assumption did they find was wrong, what feedback did they resist at first, what did they change, and what happened?
Test the operating system in the interview. Describe the real management cadence, decision rights, and expectations. Then add tension: "Your regional leaders want more autonomy. The CEO says execution is getting inconsistent. What do you do?" Probe the answer, then change one variable, such as the growth rate or the maturity of the team, and see whether the answer changes. You are testing whether the leader has principles or a preferred playbook.
Culture fit is behavioral, not personal. Ask how decisions are made, how much cadence is expected, how fast priorities change, how explicitly leaders align their teams, how often performance is inspected, and how much autonomy exists inside which guardrails. Fit is about how the work is run, never about background or similarity.
