Succession Gap for a Single- incumbent Role
A regional controller with 22 years of tenure and deep institutional knowledge of a legacy ERP is retiring in seven months. The succession plan lists 'no ready now' candidates; the two 'ready later' candidates are a senior accountant who lacks consolidation experience and a finance manager in another region who has never worked with the legacy system. The CFO wants to 'just promote the senior accountant and backfill.' The legacy ERP will be replaced in 18 months, but until then the controller is the only person who can run the month-end close and the regulatory filings tied to it. The senior accountant is well regarded but has never owned a close.
1. Evaluate the CFO's 'promote and backfill' proposal.

The proposal addresses the org chart, not the risk. The critical dependency is not the title - it is the knowledge required to run the month-end close and regulatory filings on the legacy ERP for 18 months.
- Promoting the senior accountant without consolidation experience and without close ownership creates a high probability of a missed or erroneous close during the transition, which is a regulatory and audit risk, not just an inconvenience.
- 'Backfill' does not solve the knowledge gap; the controller's knowledge is largely undocumented and system-specific.
- The finance manager from another region has consolidation depth but no legacy-system fluency; pairing the two could offset weaknesses, but only with a structured transfer.
Recommendation: treat this as a knowledge-transfer project with a hard deadline, not a promotion decision. The promotion can proceed only if paired with a documented transition plan and interim support.
2. What should the transition plan contain, and how should HR measure readiness?

The plan should be concrete and time-bound:
- Knowledge capture: the controller documents the close checklist, filing calendar, system workarounds, and key contacts - validated by having the successor execute the steps, not just read them.
- Shadow-then-lead: successor shadows two close cycles, then leads one with the controller as reviewer, before the retirement date.
- Pairing: assign the finance manager as consolidation reviewer for the first two cycles to cover the experience gap.
- Interim support: a defined retainer or part-time arrangement with the retiring controller for the first 60-90 days post-retirement, if permitted.
- ERP bridge: align the transition with the 18-month replacement timeline so effort is not duplicated.
Readiness measures: successful independent close with no material errors, sign-off by controller and CFO, and a documented checklist that a third party could execute. HR's role is to hold the timeline and escalate slippage - a 'ready later' label should be replaced by evidence of demonstrated close ownership.
