“…This coincides with the literature that states that the SRA design is based on reusing existing assets when possible [10,71,72]. In industry, it seems difficult to find futuristic/preliminary SRAs (those only based on theoretical architectural patterns instead of experience), being common practice/classical SRAs [4].…”

“…Hence, the design of an SRA usually involves reusing the essential of existing software architectures [10]. Reusable software assets are not limited to code [71], they may include algorithms and models, design patterns, scripts, technical documentation, test results, use metrics as well as other artifacts. Reuse in the design of an SRA is a cost-effective approach to create common building blocks [72], and implies the application of proven components and architectural styles that induce specific quality attributes [71].…”

Gathering empirical evidence and building a business case for software reference architectures in industry

Background: Software reference architectures are becoming widely adopted by organizations that need to support the design and maintenance of software applications of a shared domain. For organizations that plan to adopt this architecture-centric approach, it becomes fundamental to understand how software reference architectures are engineered, and to know their return on investment. Unfortunately, there is a lack of evidence-based support to help organizations with these challenges. Goal: The main goal of this PhD thesis is to support organizations making informed decisions about software reference architecture acquisition, design, and use based on empirical evidence. Methods: To accomplish this goal, we have conducted an action research approach in an industry-academia collaboration between everis (a multinational IT consulting firm based in Spain) and our Research Group of Software and Service Engineering (GESSI). Results: The results from our industry-academia collaboration led to uncover novel evidence on the use of software reference architectures in practice. The procedures and evidence obtained have been packaged to design guidelines that could be used in similar contexts as the one of everis. Conclusions: This PhD thesis supports organizations to acquire and engineer software reference architectures by providing evidence-based support. Such evidence-based support consists of the results of the empirical studies conducted in this PhD thesis, and the presented guidelines for gathering new corporate evidence. Context: Les arquitectures del software de referència estan sent àmpliament adoptades per les organitzacions que necessiten dissenyar i mantenir aplicacions software d’un domini compartit. Per les organitzacions que tenen previst adoptar aquest enfocament centrat en l’arquitectura, esdevé fonamental entendre com es dissenyen les arquitectures del software de referència, i conèixer el seu retorn d’inversió. Desafortunadament, hi ha una manca de recolzament basat en l’evidència per ajudar aquestes organitzacions a afrontar aquests reptes. Objectiu: L’objectiu principal d’aquesta tesi doctoral és recolzar les organitzacions a prendre decisions informades i basades en l’evidència empírica sobre l’adquisició, disseny i ús d’arquitectures del software de referència. Mètodes: Per aconseguir aquest objectiu, s’ha portat a terme un enfocament d’investigació-acció en una col·laboració empresa-universitat entre “everis” (una empresa multinacional de consultoria tecnològica amb seu a Espanya) i el nostre Grup d’investigació en Enginyeria del Software i Serveis (GESSI). Resultats: Fruït de la nostra col·laboració empresa-universitat, s’han descobert noves evidències sobre l’ús d’arquitectures del software de referència a la pràctica. Els procediments i les evidències obtingudes han estat empaquetades per dissenyar directrius que podrien ser utilitzades en contextos similars com el d’everis. Conclusions: Aquesta tesi doctoral és una contribució per les organitzacions que adopten i dissenyen arquitectures del software de referència, proporcionant recolzament basat en l’evidència empírica. Aquest recolzament es constitueix dels resultats dels estudis empírics realitzats en aquesta tesi doctoral, i les directrius que es presenten per la recol·lecció de noves evidències corporatives.
