Summary
- Rules come in two forms: the formal, written ones and the informal, unwritten ones that shape culture – the team's social contract.
- When rules become outdated, teams either disengage or ignore them, often with damaging results.
- Rule-breaking isn’t always bad: thoughtful challenge can spark innovation, but reckless defiance undermines trust.
- Teams perform best when they understand not just what the rules are, but why they exist.
- Leaders should keep rules under review, explaining their purpose and adapting them when they no longer serve the team.
