We propose in this paper, an approach for defining in a systematic manner, ways-ofworking providing guidelines for the development of information systems. It is a modelling approach in which a given way-of-working is constructed by instantiation of a way-of-working model allowing to deal with a large variety of situations in a flexible, decision-oriented manner.

During the final years of the last century and for the last two years the areal density of magnetic recording had been increasing at rates close to or exceeding 100% per year. That meant that each generation of hard disk drive had a digital data capacity that was close to twice that of the previous genera...
