  1. Usage of architectural styles and technologies in IT companies and organizations David Ameller and Xavier Franch GESSI investigation group, Universitat Politècnica de Catalunya (UPC)

  2. Outline • Problem statement • Empirical method used • Summary findings • Challenges and lessons learned EASA'09, Cambridge

  3. Problem statement • We are currently driving a survey to find out which architectural styles and technologies are being in use and their relation with NFRs • Non-Functional Requirements (NFR) • Selection of … for a software system • Architectural style • Technologies • We want to apply this knowledge to Model-Driven Software Development (MDSD) • We are currently developing a framework that considers NFR in the MDSD process EASA'09, Cambridge

  4. Empirical method used • The survey has been developed following an iterative methodology • Each iteration was revised by IT experts and researchers of the area • We chose LimeSurvey, a good and cheap software for developing electronic surveys • Rule-based questions allow a better design of the survey • For the dissemination of the survey • Personal contact with software architects • Advertisement in IT communities, using the power of social networks such as LinkedIn and Facebook • International Association of Software Architects EASA'09, Cambridge

  5. Summary findings (I) • We have 60 responses • When we have at least 100 responses we will publish the final results Almost all (88%) respondents use relational DB EASA'09, Cambridge

  6. Summary findings (II) • While 96% of respondents consider NFR (73% at the same level as functional requirements), only 57% use NFR to take architectural and technological decisions • 80% of respondents do not use development tools that analyze the NFR compliance, but 70% would like to use such kind of tools • The most accepted answer for all questions about interaction is that developers want to be asked, but only for the most important decisions • A great part of the respondents (79%) do not use MDSD in their software projects, so it is difficult to carry out a good evaluation of this part of the survey at this moment EASA'09, Cambridge

  7. Summary findings (III) • Non-Functional Requirements importance EASA'09, Cambridge

  8. Challenges and lessons learned • This survey can be seen as a particular instrument that addresses some of the questions raised in the EASA’09 cfp • This was an overview of the current answers to the survey, for the final report we will do a deeper statistical data analysis • We will analyze which are the most important NFR for each architectural style • Empirical evidence about the current state of software architectures usage by asking the involved actors • We found some difficulties in terminology (academia vs. IT) EASA'09, Cambridge
