Ask any board member or senior HR leader whether their organisation has a succession plan. Almost all will say yes. Ask them whether they are confident it would work if a critical leadership role became vacant tomorrow — and the conversation changes considerably. The gap between having a succession plan and having a succession capability is one of the most consequential and least-discussed failures in people strategy.

Deloitte's 2023 Global Human Capital Trends report found that only 14% of leaders feel confident their organisation has the right people ready to fill critical roles. This is not a new problem — the same survey has shown similar numbers for over a decade. What is new is the urgency. In a period of compressed leadership tenures, increased C-suite turnover, and geopolitical and economic volatility, the cost of getting succession wrong has never been higher.
The three most common failure modes
Succession plans fail in predictable ways. Understanding the pattern is the first step to building something that actually works.
Failure 1: Recency bias in identification
The people most often nominated as succession candidates are those who have been most visible recently — the ones who led the successful product launch, navigated the restructuring, or impressed the board in the last strategy session. This is natural cognitive bias at work. Recency, visibility, and articulateness are not the same as leadership potential at a higher level. Many of the most effective future leaders are quietly doing excellent work in roles that do not put them in front of the board. They are systematically overlooked because the identification process has no mechanism for surfacing them.
Failure 2: Political selection
In organisations where succession decisions are made through informal conversations among senior leaders, political dynamics inevitably shape the outcome. Succession candidates are selected based on who their sponsor is, whether they are seen as "safe," and whether they fit the cultural template of current leadership — which is usually a template built in a different era, for different challenges. The result is leadership teams that replicate themselves rather than evolving.
Failure 3: Identification without development
Perhaps the most common failure is the gap between naming someone as a successor and actually preparing them for the role. Organisations that maintain "ready now / ready in 2 years / ready in 5 years" lists but invest nothing meaningful in the development of the people on those lists are not engaging in succession planning. They are engaged in succession labelling. The label gives the organisation a false sense of security without the capability that would justify it.
The "crown prince" problem
There is a particularly dangerous variant of succession planning that plays out in family businesses, founder-led organisations, and closely held leadership teams: the designation of an heir apparent before there is any validated evidence that the individual is ready. The chosen successor — often selected on the basis of loyalty, personal relationship, or institutional seniority — begins to be treated as if they are already in the role. Rivals disengage. Development conversations become awkward. The designated successor stops receiving honest feedback because nobody wants to jeopardise their relationship with the incoming leader.
The irony is that this approach — intended to ensure continuity — typically guarantees the opposite. When the succession event eventually occurs, the "crown prince" or "crown princess" steps into the role without the rigorous preparation, honest feedback, or competitive assessment that would have genuinely prepared them. The organisation discovers too late that the plan was based on politics, not evidence.

How psychometric data changes the conversation
The most powerful thing psychometric assessment does in a succession context is remove politics from the initial discussion. When every candidate on a succession list has been assessed against the same validated framework — covering personality, cognitive ability, leadership competencies, and emotional intelligence — the conversation shifts from "who does the CEO like?" to "what does the data show about readiness, development needs, and fit for this specific role?"
This shift is profound. It allows HR leaders and talent committees to make the case for candidates who lack political sponsors. It allows for honest conversations about the gaps between a candidate's current capabilities and the demands of the target role — conversations that are impossible when succession is handled purely through informal perception. And it provides a consistent baseline against which development progress can be measured over time.
Psychometric tools used in succession contexts — including personality assessments like those available through TeamAnalys — are most effective when they are treated as structured inputs to a facilitated conversation, not as automated gatekeepers. The goal is not to reduce human beings to scores. It is to ensure that subjective impressions are tested against objective data, and that capability is evaluated rather than assumed.
Building a competency-based pipeline
Effective succession planning begins not with people but with roles. For each critical position, the organisation needs a clear and current picture of what the role actually demands — not just its current requirements, but its likely requirements in three to five years given the organisation's strategic direction. This is a more significant task than it sounds. Many job specifications are outdated by the time they are written. The competencies required to lead a marketing function in an AI-augmented business environment are materially different from those required five years ago.
Once the role requirements are clearly defined, the succession pipeline can be built around genuine capability mapping: who in the organisation demonstrates the core competencies for this role today? Who is close, with identifiable development gaps? Who has the potential to grow into it given the right experience and support? These are questions that can only be answered rigorously if there is assessment data to work from. Without it, the answers are guesses.
A competency-based pipeline also enables targeted development. Rather than sending succession candidates on generic leadership programmes, organisations can design development experiences that address specific capability gaps identified through assessment. This is development with a purpose — and it dramatically accelerates readiness.
The role of 360-degree feedback
Self-perception is notoriously unreliable as a measure of leadership effectiveness. Leaders consistently overestimate their performance on the dimensions they value and underestimate their impact on the dimensions they do not. A well-designed 360-degree feedback process corrects for this by gathering structured feedback from those who experience the leader's behaviour directly: direct reports, peers, and senior stakeholders.
In a succession context, 360 feedback serves two distinct functions. First, it provides a more complete and accurate picture of a candidate's current effectiveness than any self-report or manager assessment can deliver. Second, it surfaces the specific behaviours that need to change for the candidate to be ready at the next level — something that is invisible to any assessment that does not gather data from the people who work with them every day.
The most powerful succession readiness model combines psychometric assessment, 360-degree feedback, structured performance data, and facilitated development conversations. No single input is sufficient on its own. Together, they give talent committees the evidence base to make decisions they can defend — and that are more likely to produce the outcomes the organisation actually needs.
The cost of getting it wrong
Research by the Corporate Leadership Council found that executives hired externally in crisis successions underperform internally developed successors by a measurable margin across the first two years in role. External hires also cost significantly more — in fees, in transition support, and in the hidden cost of the cultural disruption that comes with every external leadership appointment. These costs are avoidable. But avoiding them requires building succession capability before it is needed — which is precisely what most organisations fail to do.
