The Grey Line Method® is built from three core behavioural frameworks that interact together to diagnose drift, explain pressure behaviour, and maintain belief.

• The Drift Curve™ — how small deviations become cultural norms
• The Pressure Loop™ — how pressure reshapes behaviour
• The Belief Architecture™ — how credibility strengthens or breaks

These frameworks combine to form the Grey Line Method® — a way for leaders to stabilise systems and deliver consistently under pressure.
