A brief history of the Vanguard Method

John Seddon, founder and Managing Director of Vanguard, describes the events in his career that led him to invent and develop the Vanguard Method. Beginning with his experience as a prison psychologist and student of clinical psychology, John describes what led him to switch to study occupational psychology and focus on two key elements that form the Vanguard Method: a systems thinking perspective and intervention theory. John describes his early experiences after completing his masters degree and working with Peter Edwards at Honeywell through to Vanguard's presence today, in eleven countries.
