Steve Simpson & Stef du Plessis
Deep experience.
Practical impact.
More than 35 years helping leaders understand the culture people experience—and the unwritten rules shaping everyday safety behaviour.
Years of practical culture transformation
This is not theory.
It is work we have lived.
The UGRs story
A simple idea with
profound consequences.
Steve Simpson created the UGRs concept in the late 1980s to make workplace culture tangible, discussable and changeable.
Stef du Plessis has worked alongside Steve to develop and refine the approach through sustained, hands-on work across industries, countries and cultures.
Together, they bring conceptual clarity, international experience and a practical understanding of the gap between safety intent, leadership signals and frontline reality.
Turning insight into movement.
Stef brings deep experience in helping leaders and teams confront cultural reality, build shared ownership and translate insight into practical change.

“In the 1980s it was Situational Leadership with Ken Blanchard, and Body Language with Alan Pease. In the 2000s, it was Jim Collins with Good to Great. Now is the time for UGRs.”— Guy Russo, former CEO, Kmart & Target Australia
