Computing professionals (computer science, information systems, information technology, and software engineering) have a variety of options in terms of professional association membership ranging from wide-reaching professional associations (e.g., Association of Computing Machinery) to expert users groups (e.g., Rational Unified Process Users Group) that are tightly coupled with careers or technology. Because there are so many alternatives within the computing profession, we need a reliable system to understand what motivates people to join and maintain membership in professional computing associations. Such a system would provide better insights for professional association leadership to provide targeted services to its members. Unfortunately, there is limited research that investigates the problem. The objective of this research project is to address this gap. The overarching goal of this research is to gain deeper understanding on what expectations and motives an individual has in professional computing association membership in an effort to inform decision-making by professional association leadership.
