Appendix C A Survey Questionnaire on Architecture Rationale The following is the questionnaire used in the architecture design rationale survey. It has been implemented on a web site using three static web pages. An Investigation into Architecture Design Rationale (A Joint Research Project by Swinburne University of Technology and NICTA) Disclosure Statement The purpose of this survey is to study the practices of the architecture design rationale. In order to collect the appropriate data for the research, the participants should be system and software architects and designers with at least 3 years of experience. This survey would provide insights on what industry practitioners see as important in reasoning about architecture decisions. The data will enable us to verify the theory on architecture rationalisation. This survey contains 42 questions, mostly multiple choice, and will take 30 minutes to complete. Your participation in this research is not anonymous due to the recording of your e-mail address. This survey will also collect your personal information towards the end. They include your e-mail address, gender, city of residence and information relating to your position. You may opt not to answer these questions. Should you choose to receive the final research report, I will e-mail you the research report when all the statistical information are analysed and conclusions are drawn. All data collected in this survey will be kept for 5 years in accordance with the Australian government regulations. Thank you for your support. Privacy Protection Only investigators listed below will have access to your responses. Your e-mail address is collected for the sole purpose of sending you the final research report. Your e-mail address will be kept confidential and will not be disclosed. We will not use your e-mail address in any way other than sending you the research report. Information collected in this survey, except your e-mail address, may be disclosed in research reports and will be used for research purposes only. 239
Useful Definitions The following are some useful definitions that are used consistently in the survey and will help you answer the questions in the survey: • Architecture is the fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution (IEEE Std 1471-2000). • Architecture design is the process of constructing the architecture of a system. • Architecture rationales are reasons to justify an architecture design. • Architecture rationalisation is the process of reasoning about architecture design decisions. How to fill in the questionnaire • Please answer all questions. You may skip optional questions if they are not applicable to you. • Please complete this questionnaire in a single attempt. This tool does not have the intelligence to recognise individual users to allow subsequent updates. • Please do not use the browser BACK button because it could confuse the application server. If you like to revisit the definitions during the survey, just start another window to view this page again. • You may withdraw from the survey by scrolling to the end of the questionnaire and check the withdrawal checkbox. • According to university policies, you are advised to print a copy of the complaint form after you complete the questionnaire.
