Many organisations recognise that selection and development procedures for their people are of paramount importance in order to achieve competitive advantage. Increasingly, they are turning to the Assessment Centre approach, which delivers many benefits, not only in the development and assessment work itself, but also in getting groups together. A carefully constructed and well-run Assessment or Development Centre can provide a number of benefits to an organisation seeking to improve its approach to the selection and development of their employees, which in turn can identify and predict key behaviours in the workplace that transform people performance.
