Honorary Members of the ACSG


Hermann Spangenberg started working as a teacher-psychologist at Queens College, Queenstown. After obtaining his Master’s degree in Psychology, he became a lecturer in Psychology at the University of the Western Cape. While at UWC he obtained his doctorate in Psychology at the University of Stellenbosch. He then joined Personnel Consultants, an HR consultancy firm affiliated to Sanlam. Thereafter he practised as an industrial psychologist and career consultant, where-after he served as Human Resource Director of Alwarvo, a furniture company.

Hermann probably made his most important career decision in 1977 when he became part of the HR Development team of Stellenbosch Farmers Winery (SFW). His first major project was the implementation of Performance Management country wide. While at SFW, he undertook regular extensive study visits to the USA where he became acquainted with top leadership assessment and development researchers and practitioners. With leadership and management development being the real challenge of human resource practitioners in South Africa at the beginning of the 80’s, the need to share ideas became stronger and gradually the idea of a study group emerged.

Hermann established the Assessment Centre Study Group in 1981 under the auspices of the Institute of Personnel Management. One of the features of the Study Group – particularly during its formative years – was to bring out top assessment centre experts from the USA for the annual conference. He still has great appreciation for North American experts who made invaluable contributions at a time when South Africa was not a popular destination internationally.

In view of the importance of assessment in a wider sense Hermann, with the assistance of Ben Steenberg of Eskom, established the Psychometric Congress in 1989 under the auspices of the Institute of Industrial Psychology. The Psychometric Congress was later merged with a training conference to become the present annual SIOPSA Conference. In 1990 he became professor in Organisational Behaviour and Development at the University of Stellenbosch Business School (USB) where he established the Centre for Leadership Studies. His research focused on leadership, Performance Management, and organisational performance. Since his retirement, he is still involved with updating of leadership and organisational assessment inventories in collaboration with professor Callie Theron of the Industrial Psychology Department at the University of Stellenbosch, his co-researcher for more than a decade.  Hermann holds honourary membership from the Institute of Personnel Management, the ACSG, and the Society of Industrial and Organisational Psychology of South Africa.



Prior to 1983, George Coetzee worked for government, semi-government and private organisations in South Africa. He gained valuable experience in staff selection, human resources research as well as training and development which included the application of the assessment centre technique for different purposes. In 1983 he joined Naspers Ltd, now a diversified multinational media company with interests in both the print and electronic media in more than 130 countries. He ultimately became the Human Resources Executive for the Group. Since 1998 until his retirement in 2008, he was the Group Company Secretary whilst retaining some high level human resources responsibilities. He remains involved with the Group on a part-time basis.

George first gained exposure to assessment centres at Infoplan, a subsidiary of the Armscor Group in the earlier eighties. When joining the Naspers Group, the review and realignment of their assessment centre for senior leaders was a first priority. To fulfill in the need for the assessment and development of senior editorial leaders, a fairly unique development centre was  developed using typical real-life editorial situations. In the early nineties, he developed a learning centre for successors for senior management positions. The key focus was to prepare them for the key strategic challenges of the Group using assessment centre technology, action learning and coaching. He was asked to do a presentation on this initiative at the 1995 International Assessment Centre Congress in Kansas City, USA.

George served as the chair of the Assessment Centre Study Group of South Africa from 1989 until 1995.
