Most succession plans are comforting documents. That is precisely the problem.
They create the impression of control: names in boxes, readiness colour-coded, critical roles mapped and reviewed. But a plan that looks tidy in a talent review can still collapse when reality arrives: a senior leader exits unexpectedly, a market shifts, AI changes the operating model, or transformation demands a kind of leadership the organisation has not yet built.
That is when succession stops being an HR process and becomes a business risk. Do we genuinely know who is ready? Ready for what? Based on what evidence? And if several leadership layers were affected at once, would the pipeline hold or would the organisation discover too late that the apparent bench strength was thinner than it looked?
At the same time, leadership itself is changing. Leaders must navigate AI, digital disruption, geopolitical uncertainty, hybrid working, cost pressure, shifting employee expectations and higher levels of complexity than ever before. They need commercial discipline and boldness; governance and innovation; resilience and learning agility.
Succession planning can no longer be a static spreadsheet exercise. It has to become a strategic discipline and, increasingly, a crisis and risk management tool. The question is not simply “who could replace this person?” It is “where are we exposed if the world changes faster than our leadership capability?”
There is a danger of assuming we can simply hire the answer. When internal pipelines look weak, the default assumption is often: “We will just go outside and buy the talent.” Sometimes that is the right answer. External appointments can bring fresh thinking, market insight and challenge. But as a default succession strategy, it is risky, expensive and time-consuming.
External senior hires take time to identify, attract, appoint and onboard. They may bring an impressive track record, but still have to learn the culture, relationships and strategic context of the organisation they are joining. This becomes even riskier if multiple senior layers are likely to retire over the next five to ten years. Waiting until vacancies appear is too late; organisations need an immediate plan to understand where leadership gaps may cascade and where internal capability must be accelerated now.
This issue does not only apply to CEO succession. It plays out through regional directors, functional heads, business unit leaders and critical expert roles. It also applies to emerging capabilities such as AI. Organisations cannot assume they can simply buy the digital, ethical and leadership capability needed to use new technology well; they need to build it into the pipeline. Most need both build and buy strategies. The better question is: where must we have strong internal capability because the role, capability or layer is too important to leave to chance?
Traditional succession planning often focuses too narrowly on replacing one person in one role. But organisations are systems. When a senior role changes, it affects decision rights, reporting lines, customer relationships, culture, talent movement and the distribution of power and expertise.
The future may not require a like-for-like replacement. Some roles that feel critical today may become less important as technology, strategy or operating models shift. Other roles may emerge that do not yet exist. The task is not only to develop named individuals for known vacancies. It is to build pools of talent with the capacity, agility and breadth to move into a variety of future roles.
This is where succession planning connects to organisational design. It asks: what capabilities will the organisation need as a system? Where are we over-reliant on a few individuals? Where are silos preventing movement? Where do we have depth, and where do we have single points of failure? A strong succession process should reveal organisational gaps, not just individual development needs.
Readiness is not a label — it is evidence. One of the weaknesses of traditional succession planning is the language of readiness. Someone is “ready now”, “ready in one to two years”, or “ready in three to five years”. But ready for what? Under what conditions? Against which strategic challenges? Based on what evidence?
In a more complex business environment, broad competencies are no longer enough. Words like strategic, collaborative, commercial or resilient may be useful starting points, but they are too vague to drive precise development or confident decisions. Organisations need to define the business-critical behaviours that will make the difference.
For example, if AI is changing the operating model, what behaviours will leaders need to demonstrate? Curiosity about emerging technology? Courage to challenge legacy processes? Ethical judgement about automation? The ability to bring anxious teams through change? If innovation is essential, are leaders creating space for experimentation, learning and constructive challenge?
Once these behaviours are clear, they can be assessed, developed, observed and measured. Measurement should not only show whether individuals are progressing; it should show whether the organisation is building the capability its strategy requires. Are interventions closing the right gaps? Are they shifting behaviour in the areas that matter most? Are they informing organisation design, talent movement and investment choices? Used well, measurement helps development adapt in real time so it delivers the business outcomes needed.
If succession planning is about future business performance, development cannot sit separately from strategy. Too often, potential successors attend programmes that are well designed but not connected closely enough to live business challenges. They learn concepts and language, but do not always get the experiences that stretch judgement, build enterprise perspective and test leadership under pressure.
Real readiness comes from meaningful experience: leading transformation, managing ambiguity, working across functions, handling difficult trade-offs, influencing without authority, running complex stakeholder relationships and making decisions that carry commercial consequence.
International moves can be powerful, but they are expensive and not always practical. Organisations need more imaginative, cost-effective experiences: cross-border projects, enterprise problem-solving sprints, short-term secondments, customer immersion, exposure to board-level thinking, shadowing critical decision forums, or work that cuts across silos.
The point is not to create more activity. It is to create experiences that deliberately build the behaviours the business will need. If enterprise leadership is the gap, give people work that forces them to think beyond their function. If innovation is the requirement, place them close to disruptive opportunities and expect them to test, learn and adapt.
Making space for successors matters. There is also a human tension in succession planning that is often underestimated. What happens when talented leaders are ready or nearly ready but the next role is not available? If organisations do not create stretch, visibility and momentum, they risk losing the very people they have invested in developing.
Creating space is difficult. Existing leaders may be under pressure to deliver, protective of key relationships, or reluctant to let go of work they can do well. Yet future pipeline strength depends on senior leaders consciously making room: delegating strategic work, inviting future leaders into decision-making forums, giving stretch beyond current remit and resisting the temptation to hold power, expertise or opportunity too tightly.
That mindset cannot sit only with HR or L&D. Every senior leader has a role in building the future pipeline. A culture of meaningful new experiences, shared sponsorship and deliberate talent movement has to be owned collectively. Succession is not just about preparing the next generation to step up; it is also about current leaders being willing to step back in the right ways, so others can grow.
What should HR, L&D and senior leaders do now?
There are seven practical actions organisations can take.
1. Start with the future business context. Identify the strategic shifts most likely to change what leadership success requires: AI, growth, disruption, regulation, productivity, innovation or complexity.
2. Look at the organisation as a system. Identify where roles may change, disappear or emerge, and where the business is over-dependent on individuals, functions or fragile layers of leadership.
3. Define the behaviours that will matter most. Move beyond broad competencies and describe the observable behaviours leaders must demonstrate under real business pressure.
4. Assess readiness and measure progress with evidence. Track whether people are developing against the behaviours the strategy requires, and whether interventions are closing organisational capability gaps over time.
5. Build pools of adaptable talent. Develop people for a range of future possibilities, not just one next job, through cross-functional, cross-border and enterprise-wide assignments.
6. Create space and shared ownership. Make talent movement, stretch and sponsorship a collective senior leadership responsibility, not an HR process.
7. Review succession as a live risk process. Treat it as an ongoing leadership and risk management discipline, revisiting assumptions as strategy, markets, roles and people change.
The organisations that will thrive through the next wave of leadership transition will not be those with the neatest succession charts. They will be those that treat succession as a live test of business resilience: asking what future leadership really requires, where the system is exposed, who is developing fast enough, and whether the right experiences are being created before the pressure hits.
So the challenge for senior leaders is not “do we have a succession plan?” Most do. The harder question is this: if your organisation faced a sudden leadership shock tomorrow, would your succession plan protect the business or simply reveal the risks you had not yet addressed?
