Ian Lawson is a management consultant with 30 years experience, including five years in an executive human resources position, and more than 20 years consulting to a broad range of organisations. His focus is on the hidden drivers of decision-making and unpacking complexity.

Mr Lawson completed a degree in Bachelor of Journalism (law) at Rhodes University in 1977 and a Higher Diploma in Personnel Management at Wits Business School in 1978. During the 1980s and 1990s he held executive positions in IR, and contributed significantly in negotiations with senior union officials to the creation of the sound labour relations framework that exists today.  From 1981 to 1986 Mr Lawson was employed as Group IR Manager of the largest primary packaging manufacturer in South Africa.  Here he successfully managed, in a turbulent environment, the change from a totally non-unionised to a heavily unionised environment, introduced the compulsory arbitration for disputes of right, establishment of exceptionally sound relations with COSATU affiliated unions,and facilitated agreements on the ‘right to strike’, including no dismissal, when dismissals were the order of the day. He is constantly engaged in researching and developing products and processes that lead to more effective ways of aligning people and organisations to their life conditions.

Since the 1990s Mr Lawson moved from consulting in the labour arena to focusing on transformation.  He facilitated diverse organisations in crafting strategies, plans and objectives leading to enhanced performance; working with organisations to reduce the conflict and complexity inherent in changing situations; helping individuals and groups to take advantage of their current life conditions through discovering weaknesses and playing to their strengths; and creating a consulting service to understand and resolve social complexities.
