Calling something a target operating model implies that there is a fixed point to reach. In one sense there is: an organisation can design, implement and stabilise a model against a defined strategy, set of outcomes and operating conditions.

But that target remains valid only while the assumptions behind it still hold. If policy, demand, funding, technology, workforce expectations or organisational priorities move, the model designed for the previous landscape has to move too.

So the problem is not that a target operating model can never be finished. It can. The problem is treating today’s target as a permanent destination when the drivers behind it are still changing.

The target is conditional

Every operating-model design contains assumptions, whether or not they are made explicit. It assumes something about what the organisation needs to deliver, the demand it will face, the capabilities available, the money it can spend and the political, regulatory or competitive environment around it.

A model can be completely right for those conditions and become progressively less useful as they change. That does not mean the original design failed. It means the basis on which it was designed has moved.

The term ‘target’ becomes misleading when it suggests a destination that stays put. A better target model makes its important assumptions visible and recognises the conditions that would require the organisation to revisit them.

Stability still matters

None of this means an organisation should stay in permanent redesign. Operating models need periods of stability. People have to know how work flows, where decisions sit, who owns capabilities and what they are accountable for.

An operating model is more like an evolving organism than a finished product. A healthy organism does not change everything continuously. It maintains the stability needed to function while sensing and responding when its conditions change.

The leadership task is therefore to know when stability is valuable and when maintaining it has become resistance to necessary adaptation. Constant reorganisation is not agility. It is usually just disruption without enough purpose behind it.

Continuous improvement does not tell the whole story

Continuous service or process improvement helps organisations refine how an established model operates. It can remove friction, improve performance and respond to learning without repeatedly redesigning the whole system.

But it generally assumes that the underlying model remains broadly right. Sometimes the issue is not that a service or process needs to work better. The outcomes, demand, technology, workforce or external environment have changed enough that the model itself no longer fits.

At that point, improving individual parts can keep an outdated model running more efficiently without addressing whether it is still the right model. Leaders need to distinguish between a performance problem within the model and a change in conditions that requires the model to adapt.

Design the capacity to adapt

A useful operating model does more than describe how the organisation should work today. It also creates the means to recognise when today’s design assumptions are no longer holding.

  • Make the main design assumptions explicit: the outcomes, demand, resources, capabilities and external conditions on which the model depends.
  • Agree the evidence that would show those assumptions are changing, rather than waiting for structural problems to become impossible to ignore.
  • Give leaders clear authority to adapt capabilities, decision rights, processes and deployment when conditions require it.
  • Keep enough organisational data to understand how work, demand and capability are actually shifting — not merely whether the current structure is staying within budget.
  • Review the model when material drivers change, not only when a new transformation programme is commissioned.

Transition is a beginning, not the end

Implementation still matters. Old committees, shadow processes and informal escalation routes must be closed. New capability owners need the mandate and resources to make real decisions. Someone senior must own the period when old and new ways of working coexist.

But a successful transition should not end with the assumption that the model is now done. It should leave the organisation able to operate the new model confidently, test whether it is producing the intended outcomes and recognise when the conditions behind it begin to change.

Another hill will follow

Traditional transformation language encourages organisations to reach the target, complete the handover and declare delivery. That creates false confidence if the target was based on conditions that are already moving.

An organisation can reach one hill and stabilise there. Another hill will eventually appear ahead, and changes in the landscape may mean it needs to get there in a completely different way.

Good operating-model design therefore creates something that works for the conditions of today without pretending those conditions will remain unchanged tomorrow.
