The Culture Change Playbook: How to Actually Shift Organisational Culture
JUN 17, 2026
Culture change is one of the hardest things an organisation can attempt. Here is the framework that gives it the best chance of success.
Why most culture change programmes fail
The majority of culture change programmes fail because they focus on communications and values posters rather than changing the systems and behaviours that create culture. Culture is not what an organisation says it values; it is what behaviour the organisation actually rewards and tolerates. If an organisation says it values collaboration but promotes individuals who compete rather than cooperate, the real culture is competitive regardless of what the values statements say. Effective culture change requires changing the systems, incentives, and leadership behaviours that produce the current culture.
The four levers of culture change
Research by Kotter and others identifies four levers that, applied together, are necessary for sustainable culture change: leadership behaviour (leaders at all levels must visibly model the target behaviours, not just endorse them from a distance), formal mechanisms (performance management, promotion criteria, and recognition must reward the target behaviours), informal networks (the influencers within the organisation who shape peer norms must be identified and engaged), and skill development (employees must be equipped with the skills to demonstrate the target behaviours, not just told to exhibit them).
Measuring progress
Culture change is not an event but a multi-year process. Measure progress through a combination of leading indicators (behaviour change observations, 360 feedback data, manager quality scores) and lagging indicators (engagement scores, voluntary turnover, customer satisfaction). Set realistic timescales: meaningful culture change in a large organisation typically takes three to five years of sustained effort. Celebrate early indicators of progress to sustain momentum, but do not declare victory prematurely.
