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 an unusual combination of conceptual clarity, international experience and practical understanding of what leaders encounter when culture change becomes real.

“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
