To Change Company Culture, Start with One Behavior

Summary

Organizations waste tens of billions on training that rarely changes behavior. Instead, use the 4T model: target one high-priority behavior, diagnose what blocks it, design timely interventions at decision moments, and test with experiments. Small, precise interventions compound into systemic cultural change.

Key Takeaways

1. Tens of billions spent on training yields little evidence of behavior or performance improvement. Focus on redesigning everyday moments instead of broad programs.
2. The 4T Model: (1) Target one behavior connected to cultural challenge, (2) Develop theory of change by diagnosing blockers, (3) Design timely intervention at decision moment, (4) Test with control experiments.
3. Intervene at critical everyday moments—what managers prioritize on resumes, opening moments of performance reviews, meeting structures—not months before action is needed.
4. Behavior change compounds through small, precise interventions that reshape the system around work, not by inspiring people or building capability alone.
5. Measure impact with control experiments to prove interventions work before scaling. This turns behavior change from hope into measurable strategy.

behavior underpins so many challenges in the workplace from leadership to performance to inclusion and AI adoption. Traditionally, when we've wanted to change those behaviors, we've tended to do so with the same intuitive model. We launch a communications campaign. We roll out training and development and we offer managers toolkits and frameworks. On paper, it feels like a watertight strategy. If people understand the change and they know how to do it, then surely change will happen. Unfortunate...
