Abstract
Modelling activities are central in the development and maintenance of
computerised information systems. Examples of types of models that are
developed are:
– The existing information systems in the organisation as they are
perceived by the participants of the project are modelled during analysis.
– The future information system (IS) is modelled during requirement
specification.
– The future computerised information system (CIS) is modelled during
design.
Most proposals for quality goals for requirements models as summarised
in (Davis et al. 1993) have included many useful aspects, but unfortunately
mostly in the form of unsystematic lists of desired properties. Some
researchers (Falkenberg 1996; Lindland Sindre and Sølvberg 1994; Pohl
1994) have attempted to take a more structured approach for understanding
quality. This has culminated in the work presented in (Krogstie, Lindland
and Sindre 1995a; Krogstie, Lindland and Sindre 1995b; Krogstie and
Sølvberg 2000; Krogstie 2001), and we will in this paper integrated this framework with the work of Davis et al, and in this way extend the
framework in the area of requirements models.
The paper is structured as follows. In the next section, the quality
framework is presented briefly. In Section 3, we have specialised the
framework based on the quality properties for a software requirements
specification (SRS) as presented by Davis. A summary of the results is
presented in section 4, before ending the paper pointing to future work.
