Why command-and-control doesn’t work in complex healthcare systems — and what to do instead

The assurance meeting is in two days. The team is gathered around a draft slide deck, not to ask what we can learn, change or adapt, but how to explain the position without being shouted at or appearing weak.

That is the point at which blame starts to overtake learning.

Because when assurance becomes performance, honesty becomes harder. And when honesty becomes harder, complex change becomes slower, more defensive and less effective. Worse, issues and risks are not surfaced early enough, and patients can be harmed.

That is not because people do not care or are not capable. It is because of the culture and the approach to change.

In simple environments, pushing harder can work. Cause and effect are more visible, however most healthcare systems are not simple. They are complex and adaptive. Multiple teams, professions, organisations, incentives and constraints interact at the same time. Actions in one part of the system create consequences elsewhere, often with delay, and what appear to be similar circumstances do not reliably produce the same outputs or outcomes.

This is where a systems lens matters.

Donella Meadows taught us that to understand a system, we need to look beyond events and notice patterns over time, feedback loops, delays, constraints and information flows. In healthcare, that means asking different questions. Not “Who failed?” but “What conditions made this outcome likely?” Not “Why didn’t that work?” but “What is the system reinforcing, rewarding, delaying or making difficult to see?” In complex systems, even the best-planned outputs do not always produce the outcomes we intended, because the system is complex.

Once you understand that, many “people problems” start to look more like system effects. A service repeatedly missing targets may not primarily have a motivation problem. It may be trapped in a reinforcing loop of unclear priorities, delayed decisions, hidden dependencies and poor feedback.

Information flows are one of the most powerful ways to unlock the “black box” of systems thinking. They make system signals visible, shared and useful. A statistical process control (SPC) chart, for example, is not just a performance graph; it is a way of seeing what may be happening in the system over time. Its value lies not in proving failure, but in helping people interpret variation, flow, stability, emerging constraints and where deeper inquiry is needed. That is the shift from command-and-control to systems thinking: from asking who is to blame, to asking what the system is showing us, and what that means for action.

Yves Morieux makes a similar point in Smart Simplicity. In complex organisations, the answer is not more layers, more rules or more control. It is making cooperation easier. In healthcare, that means creating the conditions in which teams, services and organisations can see the same signals, work from the same intent, and respond to the same constraints together. If the system cannot see itself clearly, it cannot adapt intelligently.

This also changes accountability. In complex healthcare systems, accountability cannot remain purely one-way and upward. There is still clear individual accountability for delivering stages and outputs, but there is also system accountability. If leaders sign up to shared outcomes, they are responsible too: for removing barriers, resolving dependencies, improving information flows and enabling delivery across organisational boundaries. This requires a genuine sign-off at the beginning, not nominal approval. If a board, commissioner or leadership group is going to hold the system to account for outcomes, it has to understand the work, the logic and the dependencies well enough to own its part in making success possible.

When information flows are clear and trusted, decision-making can also be devolved closer to where change is happening, so teams can act quickly rather than waiting for avoidable approval. In that kind of system, escalation becomes more about seeking help to solve a problem. In complex systems, review is not a meeting in a boardroom; it is an ongoing process of interpretation and sense-making.

Horizontally, the same logic applies. Learning spreads when projects and programmes are described in a more consistent way. Otherwise, every team is effectively speaking its own language, and the system cannot compare progress, see patterns, manage dependencies or spread learning at pace. This creates awareness, understanding, and knowledge, which, if managed right, creates emergence. In systems thinking terms, emergence is the creation of ideas and approaches that would never have happened if acting in isolation.

This is one of the strongest arguments for structured approaches such as Outcomes Key Results and Stages (OKRs). By creating a common spine for stages, outputs, dependencies, intended differences and review, OKRs make delivery, impact, constraints and learning visible in a comparable way. That supports better sponsorship vertically, but also faster learning horizontally.

As John Doerr has shown, clear objectives help very different parts of a system understand how their work connects to a larger mission. In healthcare, that matters even more. Complex outcomes rarely depend on one team alone. They depend on shared purpose, visible logic, clearer information flows and a system that can learn faster than the problems it is trying to solve.

Through my research and practical work with NHS teams, I have developed an approach that combines OKRs, logic modelling and AI-supported coaching. The Outcomes Key Results and Steps (OKRSs) help make stages, outputs, dependencies and intended differences more visible, strengthen review, The AI coaching enables faster, better, more considered development and review.
