How to Review an Inherited Strategy Without Rewriting It

For many strategy leaders, the most delicate moment comes not when a strategy is created, but when one is inherited.

A new Chief Strategy Officer arrives, or a strategy function is reshaped. The existing strategy may be only months old, perhaps even recently approved by the board. Yet the leadership team quietly wonders whether it still holds. The instinctive response is often to start again: commission new analysis, redesign the strategic pillars, and launch a new strategy cycle.

But this approach carries risks. Resetting strategy too frequently erodes organisational confidence and creates fatigue. Just as importantly, many strategies fail not because they are conceptually wrong, but because they are poorly implemented. Research and management literature frequently suggest that execution failure rates can reach as high as 70–90%, meaning the real issue often lies in delivery rather than design. 

For strategy leaders inheriting an existing plan, the more valuable skill is not reinvention, but diagnosis. Does the current strategy still make sense, and if not, where exactly does it break?

There are several structured ways to answer that question without triggering a full strategic reset.

Start With the Strategic Logic

The first step is to test whether the strategy actually contains a clear logic.

A surprising number of strategies collapse under this simple examination. As McKinsey has argued, a true strategy is not a financial target or a list of initiatives, but a coherent set of policies and actions designed to overcome a specific challenge. 

When reviewing an inherited strategy, leaders should therefore ask three deceptively simple questions:

• What is the core challenge the strategy is designed to overcome?

• What is the unique approach the organisation has chosen to address it?

• How does that approach create sustainable advantage?
  

If these questions cannot be answered clearly, the issue may not be execution, but the strategy itself lacks definition.

However, if the strategic logic remains sound, the focus should shift elsewhere.

Separate the Strategy From Its Implementation

One of the most common mistakes in reviewing strategy is confusing poor implementation with flawed strategic thinking.

Many organisations interpret disappointing performance as evidence that the strategy itself is wrong. Yet in practice, execution breakdowns are far more common. Misaligned incentives, unclear ownership, competing priorities, and resource constraints frequently derail otherwise coherent strategies.

A useful diagnostic is to ask:

• Are the strategic priorities understood across the organisation?

• Are initiatives clearly linked to those priorities?

• Are resources and operating models aligned to support them?
  

Research into strategy execution consistently shows that organisations performing well tend to link strategy directly to initiatives, metrics, and operational decisions. 

If those linkages are weak, the strategy may be intact while the execution system is not.

Test the Strategy Against Today’s Environment

Even well-constructed strategies degrade over time as market conditions shift.

Technology cycles accelerate. Competitive structures change. Regulatory conditions evolve. In many industries the pace of disruption has increased dramatically over the past decade, forcing organisations to reassess assumptions more frequently.

The key question for strategy leaders is therefore not whether the strategy is perfect, but whether its assumptions still hold.

Three tests are particularly useful:

Market structure: Has the competitive landscape changed in a way that undermines the strategy’s positioning?

Capability advantage: Do the capabilities the strategy relies on still represent a meaningful advantage?

Time horizon: Is the organisation investing appropriately across near-term performance and longer-term growth?

Many strategy frameworks, from portfolio models to McKinsey’s Three Horizons concept, were originally designed to ensure companies maintain this balance between present and future opportunities. 

If those assumptions remain broadly valid, the strategy itself may not require fundamental change.

Look for the Execution Gap

Even when the strategy is well designed, organisations often capture only a portion of its potential value.

Recent McKinsey research suggests that even high-performing companies frequently leave around 30% of potential strategy value unrealised, largely due to operating model and execution issues. 

This “execution gap” is often where strategy leaders should focus their attention.

Typical signals include:

• Strategic priorities competing with day-to-day operational pressures

• Lack of accountability for major strategic initiatives

• Budget processes disconnected from strategic objectives

• Transformation programmes operating outside the core business
  

In many cases, closing these gaps can unlock more value than rewriting the strategy itself.

Run Targeted Strategy Tests

A practical approach is to conduct a structured strategy stress test rather than a full redesign.

Consulting frameworks often propose a set of diagnostic questions designed to challenge strategy assumptions without resetting them entirely. These tests typically examine whether the strategy:

• Addresses the organisation’s most critical challenge

• Differentiates meaningfully from competitors

• Aligns with organisational capabilities

• Can realistically be executed given resources and operating model
  

The purpose of such tests is not to invalidate the strategy, but to identify the specific points where it may need refinement.

In many cases, only a small number of adjustments are required.

Preserve Stability Where Possible

One of the quiet responsibilities of a strategy function is maintaining organisational focus.

Frequent strategic resets create uncertainty, undermine long-term investment decisions, and can erode confidence in leadership direction. The more effective approach is often evolutionary rather than revolutionary.

Where the core logic remains sound, strategy leaders should resist the temptation to redesign the entire framework. Instead, they can refine priorities, clarify initiatives, and strengthen execution mechanisms.

In many organisations, this approach ultimately proves more effective than beginning again.

Strategy Leadership as Stewardship

Reviewing an inherited strategy is therefore less about authorship and more about stewardship.

The goal is not to impose a new intellectual model or demonstrate analytical originality. It is to ensure that the organisation is pursuing a coherent strategy, and that it has the systems, capabilities, and discipline required to deliver it.

In practice, the most valuable outcome of a strategy review is often not a new strategy at all.

It is clarity about whether the existing one is truly being executed.

And in many organisations, that alone is where the real strategic work begins.
