 Obiettivo del progetto (Objective)

'Among the critical areas of software development are Requirements Engineering (RE) and Systems Architecting (SA). There is a high degree of interaction between these two processes. While these processes have been researched in terms supporting technology, there is a distinct lack of empirical understanding regarding the scientific properties of the interaction between RE and SA. Without such empirical understanding, clearly, technical-solution proposals are less likely to be effective in practice. Thus, this proposal seeks to investigate: (1) the impact of an existing system’s architecture on the risks associated with new RE decisions; (2) the role of simulation in the engineering of the requirements of complex systems; and (3) the guidelines that can be used to support the extraction of generalisable requirements and architectural patterns from a prototypical project’s information base for use in developing production systems. These are novel objectives. The significance of the first two objectives is that they would give transparency to the analysts and stakeholders, during requirements change, as to the risks involved in changing and implementing new requirements. Assessment of such risks would be invaluable for negotiation with customers and in system design and technology development. The significance of the third objective is that the cycle-time, effort, and hence cost, for transitioning projects from prototype to production stages could reduce considerably because of the use of established guidelines. This is of strategic importance as we transition more and more “green” prototype systems into production systems. The research approach to be used will entail conducting case studies of a significant prototype automated train project (RailCab). The application domain is thus “mechatronics” (i.e., mechanical engineering, electronics, and software engineering), making this investigation inter-disciplinary.'

Introduzione (Teaser)

Not much is known about the interaction between requirements engineering (RE) and systems architecting (SA), widely considered the two most important phases of the software development life cycle. An EU initiative has examined RE and SA processes to provide insight and improve operations and technology.

Descrizione progetto (Article)

There is a considerable amount of interaction between RE and SA due to their close proximity in the life cycle. Even though both have been researched with respect to new technology such as methods, tools and processes, there is a dearth of knowledge based on empirical evidence.

With this in mind, the EU-funded RESACS (Requirements engineering and systems architecting case studies) project set out to better understand this RE-SA interaction in order to advance knowledge and deliver more effective real-world solutions. To achieve this, project members mainly carried out a series of case studies on RE-SA interactions.

Several studies concentrated on the human and technical issues that impact RE-SA interaction. This led to a theory that presents a number of conditions to enhance RE and SA processes. It also outlines the socioeconomic implications for daily operations and research.

The team devised a checklist for the specification of software requirements that targets analysts and quality assurance personnel. It is designed to avoid issues later in the development cycle.

Research was carried out to determine the barriers to regulatory and standards compliance for RE processes, specifically for a large-scale and complex systems engineering project.

RESACS has provided researchers with a solid knowledge base to further study of the RE-SA field. Management and senior technical personnel are in a better position to perform RE and SA processes. The use of an established checklist will lead to higher quality software systems, optimised project timelines and lower software development costs. Analysts and relevant stakeholders now know the risks involved in modifying and implementing new requirements. This will prove invaluable for negotiation with customers.
