Increased competition and the globalization of business have resulted in fundamental changes in the structure of organizations. These in turn have altered the nature of the employment relationship and reduced the extent of internal labour markets. The implications for traditional models of assessment are profound.

The major block to such change is the selection of those problems which are defined by the academic establishment rather than those faced by the client.
