Most succession plans are written for compliance. The ones that work are written for decisions.
Ask a Board member whether their organisation has a succession plan and the answer is almost always yes. Ask whether they would be comfortable appointing from it tomorrow — under scrutiny, with the outcome attached to their name — and the conversation changes. That gap between having a plan and trusting a plan is where most succession work quietly fails.
The compliance trap
A succession plan produced for governance review tends to optimise for coverage: every critical role has names beside it, every name has a ratio, every ratio has a colour. It reads well in a committee pack. But coverage is not readiness. A name on a chart tells you someone has been nominated; it tells you nothing about whether the organisation has evidence that they could perform in the role.
Three patterns show up repeatedly when plans built for compliance meet a real vacancy:
-
Performance is mistaken for readiness. The strongest performer in the current role is listed as the successor for the next one — even when the next role demands capabilities the current one never tests. Performance today and readiness tomorrow are different questions, and most talent matrices conflate them.
-
The evidence is subjective. Nominations reflect who is visible and well-regarded, not who has been objectively assessed against the demands of the target role. When the appointment is contested — and senior appointments increasingly are — subjective evidence does not survive scrutiny.
-
Nothing happens between reviews. A plan that resurfaces annually is a snapshot, not a pipeline. Readiness gaps identified in one review are rarely converted into development investment before the next.
What decision-grade succession looks like
Boards that get succession right treat it as a standing decision process rather than a document. The practical differences are unglamorous but decisive:
- Define the target role forward, not backward. Assess candidates against what the role will demand in three years — the strategy it must execute, the transformation it must lead — not against the incumbent’s profile.
- Insist on structured evidence. Behavioural assessment, calibrated talent reviews and independent perspectives convert opinion into something a Nomination Committee can defend. Evidence builds confidence; assertion does not.
- Distinguish “ready now” from “ready with investment” — and fund the investment. A defensible succession position typically takes twelve to eighteen months of deliberate development to establish. The plan is only as real as the development attached to it.
- Review movement, not documents. The question for each cycle is not “is the plan current?” but “who moved closer to readiness since we last met — and what does the evidence say?”
The Board’s role
None of this asks Boards to run succession operationally. It asks them to change what they accept as proof. When a Board requires evidence of readiness rather than names on a grid, the organisation’s entire talent process reorganises around producing that evidence — and succession stops being a paper exercise.
That is the standard worth holding: not a plan that satisfies the auditor, but a position from which the Board could appoint tomorrow and defend the decision the day after.
NBOL works with Boards, CEOs and CHROs to build defensible succession positions through structured talent intelligence — including the Talent Readiness Grid and behavioural evidence from NBO.CLASS. Every transformation begins with understanding — start a conversation.
