Organisation development: a formative evaluation of an OD intervention

Abstract

Rapid changes and increased competitiveness in business environments, together with greater demands by employees for improvements in the quality of their work lives, make it necessary for organisations to review their operating styles and functions. Many companies have found an answer in Organisation Development (OD) which focuses on ways in which people associated with organisations learn to diagnose and solve those problems which limit organisational effectiveness. The present study evaluates the progress of an OD intervention underway in an organisation in Zimbabwe. A formative evaluation is undertaken during an OD intervention. It is designed to assess the change effort's progress in such a way that steps can subsequently be taken to correct, modify or enhance such aspects of the intervention as may be determined by the evaluation. The study begins with a review of the company's original and revised Mission Statements as well as the present and last two sets of corporate three-year plans. These documents inform the construction of an interview guide. Individual interviews are then used to ascertain attitudes of respondents to the OD intervention and the changes it is bringing about. In addition the interviews are used to gauge the degree of commitment of respondents to the intervention. All the senior managers in the organisation are interviewed as well as the holding company's chief executive and the external consultant facilitating the intervention. The study records fundamental changes taking place in the attitudes of top managers and the first signs of an impact of these attitude changes on the formulation of company plans. Management styles and the culture of the organisation also show some change and influence on routine business operations. In addition there are early indications of an alteration of behaviour at other levels in the organisation. Business outcomes are improving and it is proposed that the benefits are due to fortuitous market developments assisted to an extent by the culture and attitude changes brought about by the OD intervention.
