It is argued that after fifteen years of office evaluationi psychologists can still make only the broadest of recommendations regarding the suitability of a design to an organisation. It is suggested that this is due to the atheoretical, non-cumulative and non-comparitive nature of the field. It is further argued that until the fundamental inadequacies in the positivist philosophical basis which exists are overcome, research will remain sterile. Attempts are made to clarify the rote of the environment for the individual and organisation and the nature of evaluation, from which it would be possible to develop a model of office evaluation.
