Why a Vague 'Ready Now' Rating Is a Riskier Bet Than It Used to Be
Key Takeaways
Succession planning has traditionally covered only the top 1 to 5% of roles, the ones judged genuinely business-critical.
That's no longer where succession planning stops. We're seeing it extend into middle management, driven by faster, more skills-based organisations needing visibility further down the org chart.
This imports the old problem into a much bigger population without the old safety net.
UK economic conditions sharpen this further right now: fewer new vacancies get approved at all, driven by cost pressures and AI-related uncertainty about future workforce needs [1][2].
At Noble Foods, a senior-level programme with the top tier's usual safety net behind it, a diagnostic phase still revealed some leaders were looking upward for direction rather than taking initiative, a pattern personality and 360 data alone had missed.
Precision buys two things: picking the right combination from the development options already available, and revealing where the standard offering doesn't cover what a person needs.
For as long as most organisations have run succession planning, it has covered only a narrow slice of roles: the top team, the top 1 to 5%, the ones judged genuinely business-critical. A vague 'ready now' rating on a role like this has always carried some risk, but it's been a survivable one. A role that critical almost guarantees the organisation will back an external search if the internal bet doesn't pay off. The safety net exists because the role itself justifies it.
That's no longer where succession planning stops. It's increasingly extending into middle management, a shift driven less by those roles suddenly becoming business-critical and more by something structural: organisations moving toward faster, more skills-based, more agile ways of working need visibility into bench strength much further down the organisation, so they can react quickly when a skill need shifts, a structure changes, or a capability gap opens up somewhere well short of the top team.
This is where the old problem gets imported wholesale into a much bigger population. The same vague 'ready now' labels that were always a soft signal at the top now cover a group of roles that never had the top tier's safety net in the first place.
The ‘Ready Now’ Safety Net That Never Extended Downward
For the top team, a generous rating carried limited downside. If the internal candidate stumbled in the first six months of a bigger role, the organisation still had a viable external market to draw from, and the case for opening that search was never really in doubt, the role was important enough to make it automatic. That safety net quietly did a lot of work. It meant nobody had to look too closely at what 'ready' actually meant for that top tier, because the cost of being wrong was recoverable.
Middle management doesn't inherit that logic. These are genuinely important roles, worth planning for properly, but rarely critical enough on their own to guarantee a business case for a brand new external vacancy the moment an internal promotion goes wrong. Employer caution across the UK labour market right now sharpens this further [1][2]: organisations are more hesitant to create a new vacancy at all, weighing cost pressures and open questions about how AI will reshape their own workforce, not because candidates are scarce, but because the case for a new headcount request has to work harder than it used to. That's a compounding pressure on top of the structural one, not the reason the risk exists in the first place. Organisations extending succession planning downward are making a reasonable choice, but that choice depends entirely on the readiness signal behind it actually being precise, for a population of roles where a vague signal has nowhere near the safety net it used to.
What a Generic Rating Actually Measures
A high-potential rating and a manager's overall impression of readiness measure something real, but not something precise. They tell you someone is broadly capable and well regarded. They rarely tell you which specific gap stands between that person and performing under the actual conditions of the next role, because most rating processes were never designed to surface that level of detail in the first place.
At Noble Foods, a proper diagnostic phase, personality profiling, 360 feedback, and a genuine look at career history, surfaced something a standard readiness rating would have missed entirely: several senior leaders were still looking upward for direction rather than taking the initiative expected of a more senior role. This is a top-tier programme, exactly the population that's always had a safety net to absorb a bad call, and the gap still went uncaught until a real diagnostic looked for it. That's worth sitting with: if a generic rating misses something this significant even where the organisation can afford to be wrong, the same blind spot is a considerably bigger problem for a role one level down, where there's no equivalent safety net to catch the mistake afterwards.
What Precision Actually Buys You
Precision isn't just a better-worded rating. It does two concrete things. First, it lets an organisation pick the right combination from the development options it already has, coaching, mentoring, stretch assignments, formal courses, rather than defaulting to whichever one is easiest to schedule. Second, it can reveal that the standard offering doesn't actually cover the full range of what people at this level need to close their specific gaps at all, which is exactly the territory this month's other post on succession plan development covers in full: skill, experience, confidence, and visibility gaps each need a genuinely different response, not one menu applied to everyone flagged as ready.
A proper diagnostic doesn't take dramatically longer to run than the conversations most organisations already have. It asks a more specific question: not whether someone seems ready, but which of the nine distinct types of experience that build genuine leadership capability this person has never actually faced. That answer is specific enough to act on. A general impression of readiness isn't.
| Generic readiness rating | Diagnostic-first readiness assessment |
What it captures | A manager's overall confidence in the person | The specific gap between current capability and the role's real demands |
Cost of being wrong, top-tier critical role | Recoverable, external hiring remains a viable option regardless | Rarely tested, since a credible fallback existed either way |
Cost of being wrong, newly-included middle management role | A prolonged wait for approval to open a fresh vacancy, if approval comes at all | Substantially lower, since the gap was known before the promotion, not after |
“They really work in partnership with you.” Louisa Hogarty, Group HR Director, Noble Foods, whose Future Leaders Programme, built on this kind of diagnostic, saw a 56% promotion rate into senior roles and 100% retention eighteen months after completion.
What This Means for the Next Promotion Decision
The question worth asking before the next internal promotion isn't whether the candidate seems ready. It's whether anyone has actually tested that impression against real evidence, given that a wrong call on a role newly brought into succession planning now has a much thinner fallback than a top-tier role has always had. Our upcoming webinar, You've Identified Your Successors. Why Isn't the Development Making Them Ready?, covers exactly this shift on 14 October.
Frequently Asked Questions
Why is succession planning suddenly covering roles below the top team?
It's largely a response to organisations becoming faster-moving and more skills-based. Leadership needs visibility into bench strength much further down the structure than before, so it can react quickly when a skill need shifts or a capability gap opens up, not because every one of these roles has become individually business-critical.
Is this argument only relevant while the UK hiring market stays this cautious?
The precision itself is always worth having, since middle-management roles never had the top tier's automatic safety net in the first place. What the current market adds is a compounding pressure on top of that: winning approval for a fresh vacancy to fix a bad call is harder right now than it was two years ago, for a role nobody has flagged as mission critical.
How long does a proper readiness diagnostic actually take to run?
Typically no longer than the informal conversations most organisations already have before a promotion decision. The difference is depth and structure, not overall time spent.
What if the diagnostic reveals someone isn't actually ready?
That's the outcome a diagnostic is supposed to make possible while there's still time to act on it, whether that means a delay, a specific development intervention, or considering a different internal candidate, rather than finding out after the promotion has already happened.
Does this mean internal promotion is always the safer choice right now?
Only if the internal readiness assessment is accurate. For a role that isn't judged business-critical, internal promotion without a real diagnostic behind it simply moves the risk from the hiring market to the org chart, rather than removing it.
