Requirements-driven software development system


Software development (SD) industry, while being the key driver of modern economy has an unacceptably high level of failures, caused to large extent by high complexity (interdependencies and variability) of requirements. SD industry has significant problems with managing this complexity with keeping track of changes and reusing knowledge from previous projects. The main barrier in overcoming these problems is lack of widely accepted and easy to apply mechanisms for expressing and reusing coherent solutions to problems formulated as user requirements.

The main objective of the project is thus to create an open framework consisting of a scenario-driven development method (precise specification language and process for the "how-to"), a repository for reuse and tool support throughout. The basic reuse approach will be case-based, where a reusable case is a complete set of closely linked (through mappings or transformations) SD technical artefacts (models and code), leading from the initial user's needs to the resulting executable application. A new problem description in the form of a requirements model can be matched with previous requirements models. The solution information (models and code) of the most similar problem can then be taken for reuse and adapted to even only partially developed requirements. Unlike for other approaches, the effort associated with preparing reusable solutions with this framework is kept to the minimum.

To develop the ReDSeeDS framework, the project will combine and enhance state of the art in the areas of requirements engineering, meta-modelling, model transformation and querying and inference techniques. This combination, while innovative by itself, will enable a completely new approach to software development based on this form of case-based reuse. Such approach should be an enabling factor for starting a true reuse-oriented SD community, based on openly available case query engines and solutions validated in practice.
