Imagine a retailer watching its conversion rate quietly decline over three consecutive months.

  • Trading puts it down to the promotional calendar
  • Marketing points to footfall
  • Store ops flags inconsistent execution
  • HR notes that team confidence has been low since the last restructure

Everyone is right. And because everyone is right about their own part, nobody solves the whole thing.
This is retail. Almost every significant challenge sits at the intersection of functions — and yet most leaders are developed almost entirely within one.

That's not a criticism of how organisations invest in their people. It's a reflection of a very human instinct: when time is short and pressure is high, leaders reach for development that feels immediately relevant. An ops manager looks for content that sharpens operational decisions. A commercial lead wants to get better at trading. The path of least resistance runs straight through familiar territory.

HR and L&D teams tend to see this clearly and spend considerable energy trying to counteract it. But it's an upstream problem. The environment has to do some of the work.

When leaders only learn with people like them

There's a cost to siloed development that rarely gets named directly. It's not that leaders become bad at their jobs, it's that they become increasingly expert in their own lane, and increasingly reliant on others to translate across it.

Consider what this looks like in practice:

  • A store manager who has never sat with someone from finance will struggle to connect their daily decisions, staffing levels, waste, shrinkage, to the numbers that determine whether their store is viable
  • A finance business partner who has never spent real time understanding how an ops team actually functions will produce cost-saving models that look clean on a spreadsheet and cause chaos on the shop floor
  • An ops manager who has never worked through a problem with a store manager will design processes that are operationally logical and completely disconnected from what's actually executable at store level

None of this is malicious. It's just what happens when development is designed, or chosen, in isolation.

The most effective leadership development environments are built to make the collision of perspectives unavoidable. Not as a module or a workshop add-on, but as the basic condition of how learning happens.

What changes when leaders learn across the business

When leaders from genuinely different functions learn together, wrestling with the same challenges, stress-testing ideas against people who hold different pieces of the puzzle, something shifts that a functional programme rarely achieves.

  • The ops manager starts asking commercial questions
  • The marketing manager starts asking what a campaign actually asks of the store teams expected to deliver it on the ground
  • The supply chain manager starts considering what a promotion actually asks of the people receiving it at store level

These aren't training outcomes written on a learning objectives slide. They're the natural result of being in a cohort where your assumptions keep meeting someone who doesn't share them.

This is part of what makes a framework like the four-lens approach (People, Planet, Profit and Purpose) at the BRC Leaders Summer School so valuable in a retail context. It doesn't ask leaders to step outside their function temporarily and then step back in. It asks them to hold multiple perspectives as a permanent habit of mind.

"A brilliant opportunity to grow, learn and unlearn. Be prepared to be inspired, challenged — and to have fun!"

Ellie, Supply Chain Manager (Imports), Dreams

That word, "unlearn", is doing a lot of work. It's what happens when your existing mental model meets genuine challenge from people who don't share it.

Why HR and L&D leaders are well placed to drive this

If you work in HR or L&D, none of this is news to you. You've seen the leaders who plateau, not because they lack capability, but because they've never been stretched beyond the edges of what they already know.

The challenge is often making the internal case for development that doesn't come with a neat functional ROI. But the evidence tends to show up in exactly the moments that matter most:

  • When a restructure needs fast alignment
  • When a change programme needs leaders who can influence without authority
  • When a senior role opens up and the pipeline is thinner than expected

Programmes like BRC Leaders' Summer School are designed with this in mind. Delegates join from across retail, different functions, different organisations, and learn alongside each other over an extended cohort experience. The cross-company networking isn't a social feature bolted onto the programme. It is the programme, in a significant sense.

"The course confirmed I'm on the right path. Leadership isn't about having all the answers — it's about curiosity, self-awareness, and growth."

Nadjib, Regional Operations Manager, BKUK

Those qualities don't develop in isolation. They develop in contact with people who see the world differently.

The compound effect

Zoom out five years. What does a retail business look like when its mid-level leaders have consistently developed alongside peers from across functions and organisations?

The answer isn't just individuals with broader perspectives. It's a business with:

  • Stronger informal networks: leaders who know who to call across the business
  • Faster internal alignment: because people have already built trust and shared language
  • Better change adoption: because leaders understand the knock-on effects across functions
  • A deeper pipeline: leaders who've grown beyond their function and are ready for what's next

The investment case isn't the programme itself. It's the cumulative effect of leaders who were never allowed to stay entirely in their lane.

Building leaders who see the whole picture

The retail leaders who grow, who become genuinely difficult to replace, tend to be the ones who learned early that their function was only ever one piece of a much larger system.

That kind of perspective doesn't come from reading about cross-functional leadership. It comes from experiencing it: from being challenged by someone who holds a different piece of the puzzle, in an environment designed to make that challenge productive.

If you're thinking about how to develop your leaders, not just within their function, but across the business, we'd love to talk about whether Summer School is the right fit.
