Leading Culture Change

Climate is what people perceive, here and now, as rewarded, supported and expected. Culture is the deeper set of shared assumptions that explains why those practices exist. Schneider, Ehrhart and Macey (2013) tie climate to how people read their work experience, and culture to underlying assumptions.

Leaders shape climate quickly, through what they do every day. Culture moves more slowly: assumptions change only when new behavior is tried, works and is reinforced over time. Schein's central point is that people read culture from what leaders actually do, far more than from what they say.

Leading culture change therefore starts with leaders' own behavior, because that behavior creates the climate from which a new culture can grow.

Schein describes the primary mechanisms as the strongest signals leaders send:

1. What leaders pay attention to, measure and control on a regular basis.
2. How leaders react to critical incidents and organizational crises.
3. How leaders allocate resources: budgets, time and people.
4. Deliberate role modeling, teaching and coaching.
5. How leaders allocate rewards and status.
6. How leaders recruit, select, promote and remove people.

These mechanisms work whether or not leaders intend them to. A leader who asks about cost in every meeting but never about safety is teaching a priority, whatever the safety policy says.

Schein's primary embedding mechanisms are therefore the levers of culture change that sit inside leaders' own conduct.

Schein's secondary mechanisms articulate and reinforce culture:

• organization design and structure;
• systems and procedures;
• rites and rituals;
• the design of physical space and buildings;
• stories about important events and people;
• formal statements of philosophy, values and creeds.

They work only when they match the primary mechanisms. At Larchfield Logistics, leaders publish new values that stress collaboration but keep bonuses tied to individual sales targets. People follow what is rewarded and measured, so the new values have little effect.

Secondary reinforcement mechanisms therefore strengthen a culture change only after leaders' behavior has changed.

At Brightwater Health, leaders want staff to report near misses openly. A change manager can help in three ways:

1. Audit the signals. List what leaders currently measure, reward, ask about and promote for, and compare it with the culture the change needs.
2. Prepare for critical incidents. The first serious near-miss report is a test. If leaders thank the reporter and fix the system, the climate shifts; if they look for someone to blame, reporting stops.
3. Align the secondary mechanisms afterward. Update procedures, recognition and stories once behavior supports them, so they confirm rather than contradict experience.

Leading culture change is therefore a leadership task that a change manager can make visible, plan and reinforce, but cannot do on leaders' behalf.

Schein's mechanisms give leaders a clear and practical view of their influence, which is their strength. They also have limits:

• Culture is not fully under leaders' control. Subcultures in professions, sites and teams have their own assumptions.
• Culture change takes years, longer than most change projects.
• The mechanisms come mainly from Schein's own observation and consulting work, not from controlled studies.

Leading culture change is therefore best treated as a sustained shift in leadership behavior, not a project with an end date.
