....The cycle continues until the parties are satisfied with the combined specification. We will now consider in more detail each of the five stages. 3. 1 Stage One: Requirements Acquisition and Conversion A knowledge based approach to requirements elicitation has been taken previously (e.g. Easterbrook 1989, Maiden and Rugg 1994, Ruebenstein and Waters 1989) A limitation of most earlier approaches is that they only supported a single viewpoint (Easterbrook 1991) An exception is Nii (1986) who treated the knowledge from each expert as a separate reasoning system. In the approach offered in this ....

....are satisfied with the combined specification. We will now consider in more detail each of the five phases. 3. 1 Phase One: Requirements Acquisition using a knowledge based approach There is nothing new about applying knowledge acquisition techniques to the problem of requirements elicitation [7, 18, 25, 32, 39]. A limitation of most earlier approaches is that they only supported a single viewpoint [8] An exception is Nii [29] who treated the knowledge from each expert as a separate reasoning system. In the approach offered in this paper the goal is to create a shared viewpoint. This phase does not ....

....theory. The way in which these fields are drawn together is novel, as is their application in the area of requirements engineering. Various aspects of the model have been described in papers published elsewhere. The model was first outlined at the third European workshop on knowledge acquisition [Easterbrook 1989]. Chapter 6 will appear in a forthcoming issue of the journal Knowledge Acquisition [Easterbrook 1991] This thesis should be regarded as the definitive treatment of the model. Acknowledgements This thesis wouldn t have happened if various people hadn t kept me going. First and foremost, ....

....overview of the field, and discuss some future trends. In particular, they predict a growing integration with related fields such as text analysis, hypermedia, and software engineering. 3.2. 4 Specification as Knowledge Acquisition Specification can be regarded as a knowledge acquisition task [Easterbrook 1989]. From this perspective, the requirements specification is treated as a knowledge base, which can then be used as a key resource to support the remainder of the software lifecycle. Requirements engineering is concerned with the creation and refinement of this knowledge base. Given this view of ....

....certain amount of knowledge. The areas of knowledge do not fit together like a jigsaw, but instead overlap in some places, conflict in others, and often leave gaps. The process of elicitation and specification of requirements can be regarded as a knowledge acquisition and knowledge management task [Easterbrook 1989]. Finkelstein, Goedicke et al. 1989] formalise the notion of a perspective into what they term a ViewPoint. Each viewpoint represents some area of knowledge and a preferred representation for that knowledge. More specifically, a viewpoint has the following components: a style, which is the ....

....are mainly to do with conflicts in personal relationships, there are other reasons why conflicts may appear displaced. For example, the descriptions being compared might be the result of long chains of development which are not necessarily based on the same initial assumptions and motivations. Easterbrook [1989] notes that simply asking people to state any assumptions made by their descriptions is unlikely to be fruitful. There will be many assumptions, goals, and motivations involved in any description, some very trivial, and only a few will be relevant to the analyst. They are idiosyncratic in that ....
