Supporting IT effectively will also mean supporting innovation in IT. Information technology both enables, and crucially depends on, a national system of innovation. Any white paper on Science and Technology should devote special attention to information technology in view of its crucial and exceptional role in technology innovation. The IT industry in South Africa, particularly niche applications development, can become a major driver of the economy, both to provide local IT solutions to development needs and to provide export products. It can be a major force in supporting employment in small, medium and micro enterprises (SMME's). The information society makes great demands on human resources. Current deployment of IT is hampered by having far too few people with an ability for innovation in IT. Exploiting the numerous potential benefits of IT will be greatly enhanced by having a more technology literate population.

This paper describes the result of a study aimed at identifying current practice in the evaluation of BPR success in South African organisations. Evidence was gathered by interviewing 18 respondents from organisations which were or had been involved in BPR projects. A framework for the evaluation of BPR projects developed by the author was evaluated against this evidence and guidelines for management which can be applied in the evaluation of BPR projects derived.

It is based on a modification of the procedure of the Analytic Hierarchy Process (AHP) by T. Saaty. The structuring of the selection procedure allows top-level management decisions to be propagated down the organisational structure. An illustration of this idea is its implementation for the selection of hardware and software in a university environment but it may be applied also for decisions in other areas as well.

However, reducing cache misses can be at the expense of more misses from the translation lookaside buffer (TLB -a cache of recent page translations). This paper presents simulation results from use of a library called OOSH (Object-Oriented Library for Shared Memory), in which cache behaviour is measured. Even for a well-optimized application, the library improves speedup by over 20% on 32 processors. On the other hand, timing on a real machine shows that the TLB problem can impact performance by as much as 25%.
