II (Ibero-American) Workshop on Requirements Engineering

Baseline Mentor. An application that derives CRC cards from lexicon and scenarios Leandro Antonelli, Gustavo Rossi and Alejandro Oliveros

Abstract.  This paper introduces a tool to help domain expert during requirements engineering phase in software development. This proposal is framed by Leite’s work on a client oriented requirements baseline (Leite 1995), which aims to model the external requirements of a software system and their evolution within it. A requirements baseline is a structure which incorporates descriptions about a desired system in a given macrosystem. The baseline is composed of five views: the lexicon model view, the basic model view, the scenario model view, the hypertext view and the configuration view (Leite 1997b). This article will not deal with basic model view; it will treat with the other four views. The baseline is extended with a strategy to derive object oriented specifications (Leite 1997). The application introduced, called baseline mentor, handles with projects. Each project contains several versions. Versions are composed of lexicon, scenarios and CRC cards. Baseline mentor allows editing and navigating through this information, making integrity and consistency checks, deriving automatically CRC cards from lexicon and scenarios, and exporting information in HTML tags, and RTF format.
