Script the Critical Moves

Script the Critical Moves is a change method for translating a broad direction into a small number of observable actions. It reduces ambiguity at the moments where people otherwise hesitate, interpret the goal differently or default to the old behaviour.

When to use it

• Turn an aspiration into behaviour people can perform now.
• Reduce avoidable choice overload in a recurring situation.
• Make a new practice easier to teach, observe and reinforce.
• Create a temporary default while people build skill and confidence.
• Avoid scripting work whose safety or quality requires expert judgement in changing conditions.

Origins

Chip and Dan Heath present “Script the Critical Moves” in Switch as part of directing the rational side of change. The method draws on decision research, implementation intentions, checklists and operational standard work: clarity about the next behaviour can free people from re-deciding the same issue repeatedly.

What it is

A critical move is a specific action in a defined situation. It is not a value, personality trait or desired outcome. “Deliver excellent service” is an aspiration; “acknowledge every unresolved request before handoff and name the next owner” is a behaviour that can be taught and observed.

A script can be a rule, checklist, default, sequence or if–then response. Good scripts define the smallest set of moves that carries disproportionate value. They leave judgement available outside that boundary and include an escalation path for exceptions.
