Adapted from the upcoming book 'Practice Makes Culture', this piece argues that organizational culture is shaped not by mission statements or declared values, but by repeated small behaviors in everyday interactions. The 'practice gap' — the disconnect between stated values and actual behavior — is illustrated through common workplace examples. Drawing on habit formation research (James Clear, BJ Fogg), the authors contend that culture is the accumulated weight of thousands of small moments: how meetings run, how disagreements unfold, how decisions are made. Practical techniques include 'welcoming elephants' (naming unspoken tensions openly), creating genuine ownership by involving people in change rather than imposing it, and making small deliberate behavioral shifts in meetings. A case study from LPL Financial illustrates how inclusive planning practices transformed culture without a formal values campaign.
