The last mile problem: why operating models fail in execution

Most operating models don’t fail in their design

They fail in the last mile. The moment the model meets real-world pressure, competing priorities, and human behaviour.

Executives feel this long before the organisation admits it. Delivery slows. Decisions stall. Teams improvise. This is the moment when the clues start to add up and the model that looked elegant in the board pack suddenly starts to feel fragile in practice.

Not because the model is wrong. But because the last mile is where the organisation reveals what it actually runs on: behaviour, power, trust, and clarity.

What the last mile problem looks like

Different roles, different symptoms, but all have the same root cause. The last mile exposes the behavioural reality every operating model is built on top of.

Example 1: The CPO whose teams are “aligned” but not actually aligned

A Chief Product Officer at a major player in the insurance sector rolls out a new prioritisation framework. Everyone nods. Everyone agrees. Everyone commits. But in the last mile where decisions need to be made, each function interprets the framework differently.

The result? Three versions of “priority”, four versions of “capacity”, and a roadmap that looks aligned on paper but is fractured in reality.

She is not dealing with resistance. She is dealing with the different perspectives and biases through which the framework is being interpreted.

Example 2: The CIO who can’t get cross-functional teams to make decisions without him

A Chief Information Officer in an ASX100 organisation introduces the concept of empowered teams as they embrace the usage of AI. The intent is clear: faster better quality decisions closer to the work because the bottleneck is no longer in the build time - it’s in validating which ideas are worth chasing and what bets are the ones to make in an overly noisy technological landscape.

But in the last mile, teams hesitate. They escalate. They wait for permission. Not because they’re incapable, but because the organisation hasn’t built the psychological safety or clarified boundaries or defined decision rights to support true empowerment.

He is not facing a capability gap. He is facing a clarity and confidence gap.

Example 3: The COO who sees the model working, until a crisis hits

A Chief Operating Officer in a large retail company watches the new operating model hum along until the first customer-impacting incident occurs. Then the old escalation paths reappeared. The old decision makers stepped back in. The new roles got bypassed and the organisation snapped back into its pre-transformation shape.

She was not watching a failure. She was watching stress regression occur the moment pressure exposes the real hierarchy within the organisation that cannot be bound by mere titles and org chart diagrams.

Example 4: The GM in Product who realises the model depends on relationships, not structure

A General Manager in Product at a tech-enabled business sees that delivery only flows when certain leaders are in the room when decisions are made. When they’re not in the room, decisions stalled.

The model isn’t broken. The trust fabric is. People hesitate to make decisions because consequences are real and risk aversion rules when decisions have been made by certain individuals for far too long. What happens when you take that step and make the decision then it goes pear shaped?

No amount of structure compensates for a leadership team that hasn’t built the relational capital and trust required to alleviate the fear of disproportionate consequences when something goes wrong instead of right.

Example 5: The Head of Transformation who sees the model drifting but can’t get the exec team to name it

A Head of Transformation notices the early signs: side deals, shadow governance, and quiet workarounds.

He raises it, people nod, but nothing changes.

He is not lacking insight. He’s lacking the power to achieve true executive alignment. The kind of power that earns them the right to have the required yet uncomfortable conversations most organisations avoid.

Why the last mile is where transformations succeed or stall

The last mile is where:

• Clarity becomes ambiguity,

• Empowerment becomes hesitation,

• Alignment becomes interpretation,

• Governance becomes negotiation, and

• Structure becomes behaviour.

It’s the moment the organisation reveals whether it has the leadership maturity, behavioural consistency, and political alignment to run the operating model it designed.

Consultancies don’t fix this. Templates and playbooks don’t fix this. Training doesn’t fix this. Only real behavioural change does this.

A quick reflection if this resonates

Take 60 seconds to ask yourself:

“Where is our operating model breaking down in the last mile, and what behaviour is driving it?”

You’ll know instantly and that insight will tell you exactly where your transformation is at risk.

If you want to go deeper, ask:

“What happens under pressure, and who steps in when the model wobbles?”

That’s where the truth of true power sits.

What the reflection tells you

If you can see the last mile cracks, you’re already ahead of most organisations. The question isn’t whether the model works. It’s whether the humans that operate the model can run it under pressure.

Leaders who get ahead of this don’t redesign the model. They stabilise the behaviours that make the model real.

If you’re seeing the last mile cracks, now is the moment to act

You don’t need another operating model. You need the one you have to work.

If you’re ready to steady the system, let’s work on this together. Here are three ways:

• Interim Executive - when the transformation needs a senior leader inside the organisation to stabilise, steer, and deliver,

• Capability Building - when product and transformation leaders are expected to know how to navigate the people, politics, and performance expectations that come with their jobs, yet no one has taught them these skills during their entire career, and

• Executive Coaching - when senior leaders need a confidential, strategic partner to think clearly, make decisions, and lead through change and complexity.
