Introducing Variability in a Client-Oriented Requirements Engineering Process

It is a good practice to consider the adaptation of any process to particular situations. This applies to Requirements Engineering where the requirements production process becomes adaptable to particular situations. Indicators depicting these situations should be created in order to guide the choice of the requirements process that best suits each specific case. Almost all literature offers a fixed requirements process independent of the context where it will be carried out. Top-down and bottom-up approaches are the most widespread ones, though middle-out approaches or combinations of them sometimes provide more accurate solutions. Our present research project “Adaptability and Completeness in Requirements Process” is centered on improving a well-developed requirements process based on natural language models (a glossary, scenarios and requirement specifications). The idea is to establish the factors that may influence a software project and the adaptations that may be introduced in the requirements process.
