Leaders create risk when they improve execution faster than they question whether the underlying assumptions still deserve to be executed.
Many leadership problems are treated as execution problems.
Results fall short, so leaders increase monitoring. A program misses milestones, so governance becomes tighter. Customers complain, so teams are told to respond faster. Margin falls, so cost pressure increases.
Sometimes these responses are correct.
Sometimes they make the wrong system more efficient.
The leadership-development material distinguishes single-loop learning from double-loop learning. Single-loop learning improves action within an existing set of assumptions. Double-loop learning questions the assumptions, goals or values that define the action in the first place.
For senior leaders, that distinction is strategic.
The Strategic Context
Organisations need repetition.
Processes, policies, standards and routines allow work to scale without every decision being reinvented.
But routines also embed assumptions.
A planning process assumes something about predictability. A pricing model assumes something about customer value. A governance structure assumes something about risk and decision rights. A portfolio assumes something about future demand.
When those assumptions remain valid, execution discipline creates value.
When they become invalid, discipline can entrench failure.
What Leaders Commonly Misread
The first mistake is equating persistence with leadership strength.
Continuing to execute a failing assumption is not resilience.
The second mistake is treating every setback as evidence that people did not follow the plan closely enough. Sometimes the setback is evidence about the plan.
The third mistake is confusing the current metric with the real objective. A program can hit milestones and still fail to create the intended benefit.
The fourth mistake is waiting for crisis before questioning the model. By then, options may have narrowed.
Reframing the Issue
Leaders need two learning modes.
Single-loop: Are we executing the chosen approach correctly?
Double-loop: Is this still the right approach, and what assumptions make us believe it is?
Neither mode is superior in every situation.
Single-loop learning supports reliability. Double-loop learning supports adaptation.
The strategic capability lies in knowing when to switch.
Assumptions Are Hidden Decision Infrastructure
Every strategy contains assumptions about cause and effect.
If we invest here, customers will respond.
If we centralise this function, efficiency will improve.
If we introduce this technology, productivity will rise.
If we restructure the program, accountability will improve.
These statements are not facts merely because they appear in an approved plan.
Leaders should make critical assumptions explicit enough to test.
A useful discipline is to ask:
What must be true for this decision to work?
That question turns implicit belief into something that can be monitored.
Self-Awareness Is Strategic When It Reaches the Model
Self-awareness is often described in interpersonal terms: understanding how others experience the leader.
That matters.
But senior leaders also need awareness of their cognitive commitments.
What ideas are they defending because they authored them? Which evidence do they dismiss because it threatens a previous decision? Which goals have become symbolic rather than useful?
Double-loop learning requires enough self-awareness to recognise that personal identity can become attached to organisational choices.
Failure Is Data, Not Automatically a Verdict
A setback does not prove that the strategy is wrong.
It also does not prove that execution is weak.
The leadership task is diagnosis.
A manufacturing improvement may fail because the technical concept is wrong, because operators were not involved, because the process constraint sits elsewhere or because the trial was poorly executed.
Each interpretation implies a different response.
Double-loop leadership prevents premature certainty.
Decision Framework
Use a two-level review.
Level 1: Execution
- Did we perform the agreed actions?
- Were resources and capability adequate?
- Were decisions made at the right time?
- Did interfaces function as designed?
- Was the result affected by identifiable execution failure?
Level 2: Assumptions
- What did we believe about customers, technology, behaviour, cost, time or risk?
- Which evidence supports those beliefs?
- What evidence now challenges them?
- Have conditions changed?
- Is the objective itself still worth pursuing?
Escalate to Level 2 when repeated execution correction does not improve the outcome, when external conditions change materially, or when new evidence challenges a core premise.
From Strategy to Execution
Immediate action: add an assumptions section to major decisions, programs and strategic initiatives. Make a small number of critical assumptions explicit.
Medium-term capability building: use after-action reviews to examine not only what happened but how the original reasoning worked. Reward leaders for identifying invalid assumptions early rather than protecting sunk decisions.
Long-term strategic positioning: create governance that distinguishes delivery variance from strategic invalidation. Portfolio reviews should be able to stop, reshape or defer initiatives when the underlying case changes.

Signals to Monitor
Warning signs include repeated explanations that blame execution without revisiting the plan, initiatives protected because of money already spent, leaders who treat challenge as disloyalty and metrics that improve while benefits deteriorate.
Another signal is excessive certainty. When an organisation cannot state what evidence would cause it to change direction, it may no longer be managing an assumption. It may be defending a belief.
Positive signals include explicit hypotheses, decision reviews that separate execution from strategy, leaders changing direction before crisis and teams able to challenge the model without attacking the person.
Questions for the Leadership Team
- What must be true for our current strategy to work?
- Which assumptions are most consequential and least tested?
- Are we correcting execution when we should be reconsidering the model?
- What evidence would cause us to stop or redesign this initiative?
- Which decisions have become difficult to challenge because senior leaders are personally associated with them?
- How do we distinguish resilience from persistence in a failing approach?
Closing Perspective
Execution discipline is essential, but it can become dangerous when applied to assumptions that no longer hold.
Leaders need the ability to improve the system and the courage to question the system.
Single-loop learning asks how to perform better.
Double-loop leadership asks whether better performance would take the organisation in the right direction.
