- W4238093085 abstract "Studies have shown that maintenance is up to 80% of the life-cycle effort of developing and maintaining a business information technology (IT) system. There are several factors which significantly affect maintenance work. This paper concentrates on one of these factors which is the knowledge staff require for effective and efficient systems maintenance. The knowledge required is split into two categories. Firstly, there is the knowledge of the business environment within which an IT system operates. Secondly, there is the knowledge of the technical IT system, particularly the details of the software structure. It is argued that both categories of knowledge are equally important and difficult to acquire. Examples of techniques for improving this knowledge are discussed. The article is partly based on case-study research into the actual practice of systems development and maintenance in 31 UK IT departments." @default.
