To be effective, new technology must meet the needs of the organisation into which it is installed. These needs may be expressed at different Ievels in terms of goals, organisational objectives and individual task needs. Any measure of successful implementation must take into account the inter-relation between these factors, rather than treat them individually. If the intended educational benefits are ultimately to be achieved it is imperative that systems adequately meet the business and/or curriculum needs of schools, contribute to effective organisational activity and meet the task and human/social needs ofthe user.Research in the industrial and commercial sectors has shown that the success rate of introducing IT systems into organisations could be as low as 20%. This is obviously a worry if such a Ievel of success is transferred to the education sector when the future and careers of so many people is at stake. This paper summarises work done in trying to develop strategies, derived from evaluation tools developed in the business sector, which can help to measure the organisational needs of schools and contribute to the evaluation of the IT systems through the task analysis and user acceptability audit, which provides data to feed back into implementation to reduce the possibility offailure and rejection by administrators and teachers.
