Most organisations are relatively good at defining strategy.
The harder part is changing how the business actually operates once the strategy changes.
A new direction may call for different markets, different customers, new capabilities or a different balance between growth, efficiency and investment. Yet the organisation often continues to make decisions through the same structures, budgets, KPIs and functional priorities that were designed for the previous strategy.
That is where execution starts to break down.
A strategy can change on paper much faster than an operating model changes in reality.
Strategy creates new trade-offs
Any meaningful strategy changes what the business needs to optimise.
Growth may require investment before returns appear. Customer responsiveness may require more flexibility. A new segment may need resources that historically belonged somewhere else. Global scale may conflict with local market needs.
These are not implementation details. They are strategic trade-offs.
If those trade-offs are not made explicit, different parts of the organisation will interpret the strategy through their existing objectives.
The result is often not resistance to the strategy. It is something more subtle: every function continues doing what is rational from its own perspective, while the organisation struggles to move in one direction.
Decision rights reveal the real operating model
One of the clearest ways to understand an organisation is to look at how important decisions are actually made.
Who owns the outcome?
Who can commit resources?
Who can change priorities?
Who can veto a decision?
Where are conflicts resolved?
A business may declare something a strategic priority while requiring every important decision to pass through structures optimised for different outcomes.
When that happens, execution slows and accountability becomes blurred.
Accountability without decision authority creates escalation. Decision authority without accountability creates fragmentation.
The operating model needs to connect the two.
This does not mean centralising every decision. Strong organisations are often very decentralised.
What matters is clarity: decisions should sit where the best combination of knowledge, speed and accountability exists.
Functional excellence is not always business performance
Functions are essential. They create expertise, standards and scale.
But individually strong functions do not automatically produce strong end-to-end outcomes.
Sales may optimise growth. Operations may optimise efficiency. Portfolio teams may reduce complexity. Procurement may reduce cost. Finance may optimise return and working capital.
Each objective can make sense on its own.
The business still has to decide how those objectives should be balanced against the overall strategic outcome.
A company can therefore be locally optimised and still underperform as a business.
This is why transformation cannot stop at organisational charts.
The real operating model also includes recurring management routines: how resources are allocated, how investments are approved, how performance is reviewed, how priorities are changed and how cross-functional conflicts are resolved.
Changing reporting lines can be relatively quick.
Changing how an organisation repeatedly makes decisions is much harder — and usually much more important.
Strategy becomes real through different decisions
The strongest test of a transformation is not whether people can explain the strategy.
It is whether the organisation now makes different decisions because of it.
Have resources moved?
Have priorities changed?
Are accountabilities clear?
Are functional objectives aligned with the business outcome?
Can important trade-offs be resolved at the right level and at the right speed?
If those mechanisms remain unchanged, the organisation may understand the new strategy while continuing to operate according to the old one.
Strategy becomes execution only when direction, accountability and decision-making reinforce each other.
That is why strategy often fails when the operating model does not change.
Questions worth asking
Which decisions must be made differently if our strategy has genuinely changed?
Do accountability and decision authority sit in the right place?
Where are functional objectives competing with the overall business outcome?
