Integrating the role of requirements specification into the process of prototyping: the protospec

Context Prototyping is an established practice within product and user interface design that is also used as a requirements engineering (RE) practice within agile development. Even so, there is a lack of theory on prototyping. Aims Our main research objective is to support practitioners in improving on their prototyping practices. Method We have designed a model that describes key aspects of the practice of prototyping. The model is based on a systematic mapping study consisting of thirty-three primary studies and on empirical data from twelve case companies. We validate and demonstrate the applicability of our model through a focus group at one company and through semi-structured interviews at eleven (other) startup companies. Results Our prototyping aspects model (PAM) consists of five aspects of prototyping, namely purpose, prototype scope, prototype media, prototype use, and exploration strategy. This model has enabled practitioners to discuss their prototyping practices in terms of the concepts provided by our model. Conclusions The model can be used to categorise prototyping instances and can thereby support practitioners in reflecting and improving on their prototyping practices.

The rapid growth in the use of expert systems has led to widespread interest in techniquesfor their evaluation, which includes verification and validation. Evaluation techniques in the sofrware engineering c~)mmunity are well established hut there are different opinions about the effectiveness of transferring sofrware engineering methodologies to expert systems. This paper outlines some of the issues involved in evaluating expert systems and cites almost 200 significant papers on the topic. We present it with the expectation that it will help both new and established researchers become acquainted with the literature of an important and gimvincqfield.
