Picture this: an organisation invests heavily in developing its senior leadership team: strategy days, executive coaching, a well-funded programme for the people already at the top. Meanwhile, the frontline supervisors managing day-to-day performance and the new managers stepping up for the first time have no formal training or structured development plan. Six months later, the senior team’s new strategy is landing unevenly, filtered through middle managers who were never equipped to translate it and supervisors who don't have the skills to make it stick on the ground. The investment at the top wasn't wasted. It just couldn’t do its job alone.
The gap most organisations don’t see
Many organisations concentrate their leadership development strategy at one or two levels, usually new managers, or the senior team, and leave the rest of the leadership pipeline to chance. Ask most human resources or learning and development leaders where their training budget goes and the answer is rarely ‘everywhere it’s needed’. It’s usually wherever the loudest problem, or the most visible cohort, happens to be.
Writing in HR Director, City & Guilds’ Mandy Smith made a similar case: the managers who determine whether people ‘feel capable, included and able to progress’ are rarely the ones at the top of the organisation chart, they’re the frontline supervisors and first-line managers shaping day-to-day experience. Her conclusion was clear: ‘extra chairs in the boardroom are no longer a leadership fix’.
That case is sharpened by the funding pressure that employers and training providers are already navigating, with a number of leadership and management apprenticeship standards losing funding this year – the exact routes that have traditionally built these capabilities. What’s needed instead is a system that supports progression from first steps through to senior responsibility, rather than treating leadership development as a single intervention at a single level.
Why every level matters
A leadership pipeline behaves like an actual pipeline: what happens at one level shapes what’s possible at the next. Failing to invest in frontline supervisors creates the exact bottlenecks that undermine middle managers, who inherit performance problems that started several rungs down. Middle managers that have never received training bear the impact of whatever strategy senior leaders set, because they can’t translate it into daily practice. And senior leaders without ongoing development struggle to model the behaviours they expect further down the ladder, no matter how good their intentions.
Play this forward and the pattern becomes obvious. A supervisor who’s never been taught to manage a difficult conversation lets a performance issue drift for months. It lands on a middle manager’s desk as a bigger, messier problem than it needed to be, one that now eats into the time that manager should be spending turning strategy into action. That manager, in turn, has less capacity to flag what’s happening on the ground, so senior leaders end up setting direction based on a picture that’s already out of date. None of this shows up as a single failure. Instead, it shows up as an organisation that feels slower and less productive than it should, without anyone being able to say exactly why.
Every level also needs a visible, credible career progression pathway, supported by a connected system of development rather than a single, disconnected training session. A frontline supervisor who can see a route towards middle management is a different proposition to one who’s been trained once and left to work out what’s next alone. The same is true in reverse: a senior leader who was promoted on results alone, without ever building the coaching or communication behaviours expected of them now, can find themselves managing a level of complexity they were never actually prepared for.
The compounding business case
The ROI of leadership development compounds rather than adds up. ILM’s own data shows that 88% of employers report their organisation was immediately and positively impacted by what employees learnt through ILM’s structured development programmes. That number describes what happens when one level is developed well. Multiply that across frontline, middle and senior levels working from the same set of expectations and the return compounds.
There’s a wider UK context here too. Analysis of ONS data has linked people management practices, including performance management, training and promotion, directly to productivity variation across firms, and the London School of Economics has identified raising management capability as central to how organisations adopt new technology and improve productivity. Leadership development at every level is vital for an organisation to be productive and, ultimately, commercially successful.
Building the whole ladder and strengthening every rung
Building a leadership pipeline this way doesn't mean starting from scratch. It means treating leadership development as a ladder to be built deliberately, rather than a single rung to be reinforced. That’s the thinking behind ILM’s approach: qualifications that map onto real stages of a leadership career, from frontline leadership training through to senior leader development, so that developing leaders at all levels connects to whatever comes next.
A leadership pipeline is only as strong as its weakest rung. Organisations that build capability consistently, at every level, don’t just fix one problem – they increase the return on everything they’ve already invested.
