Design Dimensions for Software Certification: A Grounded Analysis

Abstract: In many domains, software systems cannot be deployed until authorities judge them fit for use in an intended operating environment. Certification standards and processes have been devised and deployed to regulate operations of software systems and prevent their failures. However, practitioners are often unsatisfied with the efficiency and value proposition of certification efforts. In this study, we compare two certification standards, Common Criteria and DO-178C, and collect insights from literature and from interviews with subject-matter experts to identify design options relevant to the design of standards. The results of the comparison of certification efforts---leading to the identification of design dimensions that affect their quality---serve as a framework to guide the comparison, creation, and revision of certification standards and processes. This paper puts software engineering research in context and discusses key issues around process and quality assurance and includes observations from industry about relevant topics such as recertification, timely evaluations, but also technical discussions around model-driven approaches and formal methods. Our initial characterization of the design space of certification efforts can be used to inform technical discussions and to influence the directions of new or existing certification efforts. Practitioners, technical commissions, and government can directly benefit from our analytical framework.
