Gruppo S.I. and University

Gruppo S.I. was founded with the awareness that to guarantee quality and innovation of the IT solutions to be offered to the customers, it would not have been enough to keep updated on the evolution of the IT technologies. In fact, none technology alone can guarantee the success of a software project that aims at implementing the automation of entire subsystems of a complex production organization. The preliminary requirement is the adoption of a rigorous and formal software development process based on the "best practices" of the Software Engineering domain. To pursue this fundamental objective, the strategic choice of Gruppo S.I. has been that of playing an active role in the scientific research.

Since 2008, Gruppo S.I. has been involved in scientific and technological research with professors from the Department of Industrial Engineering and Information and Economics, of the University of L’Aquila. The collaboration was implemented along three lines. First, by funding scholarships for PhD programs. Second, by allowing engineers present inside our group to acquire the title of PhD in the field of Information Engineering and Modeling of Information Systems. Eventually, by participating in research in the field of methodologies for developing Web applications. The results achieved were presented at international conferences by staff of Gruppo S.I. and their validity has been defended by confronting with experts from academia and industry. The list of the main publications, starting from 2008, is given at the bottom of this page.

An innovative industrial methodology for the development of Web applications in Model-View-Controller architecture and a proprietary source code generator are the synthesis of the research and industrial validation activities carried out by Gruppo S.I. . The methodology rests on four pillars: (a) formal rigor, guaranteed by the adoption of the Unified Modelling Language (UML) [OMG- UML, 2017]; (b) the Rational Unified Process as reference software engineering process [RUP, 2003]; (c) the Model-Driven-Architecture as conceptual framework [OMG-MDA, 2003]; and (d) a proprietary code generator that carries out the automatic transformations across the MDA’s levels. Our methodology shifts the emphasis of the software application development from programming of the source code to the modeling of the business activities of the company, by giving a central role to the Use Case UML’s construct [Armour and Miller, 2000]. The biggest innovation brought by the Use Case construct is that it exists in the business context independently from the automation process: the software designer only needs to discover the use cases in the enterprise system and then reproduce them in the software application. Our methodology has been applied to the development of software in important industrial contexts such as the banking sector, the insurance sector and the transportation.
