Over the years, there have been quantum changes in the industry whereby the environment and industrial conditions have become more volatile. An example has been the application if IT in almost all parts of the organization from manufacturing to communication and so forth. This coupled with the increasing and ever changing competitive threats from overseas. The role of the management accountant as the sole provider of information is threatened by information specialists such as system analysts and operational researchers. To mitigate this, the management accountant is forced to become adaptable with a sufficient knowledge of a range of relevant disciplines so as to be able to provide right information at the right time. He must be prepared to keep up to date and master new concepts, principles and techniques. At all times he must be critical of existing system information and their continuing relevance in the future. The position of management accountants in the future will not be a comfortable one but will be challenging and worthwhile.
