Why aren’t people doing what I say?

Most organisations are designed to manage assets, not behaviour. They invest heavily in strategy, facilities, equipment, systems, processes, compliance, training, and talent. These investments are visible, measurable, and relatively straightforward to govern. They can be budgeted, approved, audited, reported, and optimised.

Yet none of them creates value on its own. Value is created when people make thousands of decisions each day.

• Collaborate, or protect their territory.

• Escalate a risk, or stay quiet and hope it resolves itself.

• Share information, or sit on it.

• Challenge an assumption, or let it pass to avoid the conflict.

• Prepare properly, or do just enough to get through the meeting.

Organisational assets only become productive when people behave in ways that let them. The operational conditions that enable execution are leadership alignment, trust, accountability, communication, recognition, reinforcement, and collaboration across organisational boundaries. They are intangible but determine whether organisational capability translates into organisational performance.

Which leads directly to the first paradox:

1. Organisations invest heavily in assets, but assets only create value when they are activated through behaviour.

The second paradox follows close behind.

Senior leaders are accountable for organisational performance. Yet in any large organisation, most of the behaviours that actually determine performance happen several layers below where strategic decisions are made.

Senior executives define strategy, approve budgets and resource allocations, redesign the org chart, and monitor results. What they cannot do is command trust and mandate commitment across the organisation that is outside their direct control. They cannot force two functional or local teams to genuinely collaborate or make a subject-matter expert take real ownership just because the org design says they should.

What they can do — and must do — is build the conditions that make those behaviours more likely to show up.

Which gives us the second paradox:

2. Senior leaders are accountable for outcomes that depend on behaviours they can influence but not directly control.

A third paradox follows from this one. The closer the work is to where value actually gets created, the less visible it tends to be to the people accountable for the outcome.

Value is created in laboratories, on production lines, in customer conversations, in project teams, and in the countless handovers that connect one function to another. Yet as organisations grow, an increasing share of management attention is absorbed by aggregated information: governance, reporting, budgeting, coordination, and compliance oversight. This is necessary proxy work, but the behaviours that matter most — collaboration, knowledge-sharing, problem-solving, early escalation — happen between the people closest to the product, the service, or the customer. Which is exactly where senior attention is typically thinnest.

So, here's the third paradox:

3.  The behaviours that create value are often least visible to those accountable for the outcome.

And the problem compounds as organisations grow larger and more complex.

Functional and matrix structures exist for good reasons when organisations scale. They organise and build expertise, efficiency, and accountability. Yet they also create competing incentives, local optimisation, and separate identities.

Cross-functional work, as a result, is always a guest in someone else's house. It asks people to prioritise the collective outcome over their own functional one — usually without changing a single incentive that actually drives their behaviour. So, when pressure rises, people do what people do: they optimise for whatever their own boss notices, rewards, and protects. Cross-functional priorities almost always lose to functional priorities unless leaders deliberately make them equally important.

Which is the fourth paradox:

4. The structures that optimise organisational scale can also become behavioural barriers to organisational performance.

This is exactly where most change programmes and executive orders quietly fail. The strategy is sound. The business case is compelling. The technology works, the process is solid, the resources are allocated, and on paper, the organisation looks ready.

And still, executive decisions fail to convert into results—or, as the exasperated executive put it, "People don't do what I say." The failure, as we argued, rarely lies in the strategy, technology, or process. It lies in the structures, incentives, and behavioural conditions that determine whether people can bring that design to life.

And we believe that this challenge is about to matter more, not less.

For decades, competitive advantage came from superior information, analysis and expertise. As AI takes over more of the cognitive work, such as analysis, forecasting, and decision support, the competitive edge that used to come from simply being the smartest executive team in the market is shrinking. Technology can surface opportunities and distribute knowledge to every competitor. What remains as difficult as ever is mobilising people around newly available intelligence toward a shared objective, and sustaining collective action over time.

“In practice, we have rarely seen a transformation fail because the process was unclear. More often, it failed because the behavioural expectations were never made explicit.”

As the pace of change accelerates, behavioural capability may become one of the few remaining sources of competitive advantage that cannot simply be bought off the shelf.

There is irony in all of this: behavioural work is one of the least visible, least celebrated parts of management. Executive decisions are analytical, often fast, and carry real prestige. Behavioural work is slow, repetitive, sometimes conflict-ridden, and almost entirely invisible. There's no shortcut for it — only observation, coaching, difficult conversations, reinforcement, relationship-building, and persistence.

Which is really another way of saying what we started with: people don’t do what you say—they do what the system rewards. And in a world where technology, information, and analytical capability are increasingly accessible to everyone, the ability to shape and activate human behaviour may become one of the last remaining sources of competitive advantage.

People don't do what you say. They do what the system rewards.
