Abstract
This paper presents a survey of Assurance Case implementation for applications which are not directly related to the usual for Assurance Case regulatory regime. The UK is the country which first developed the theory of Assurance Case as a response to big catastrophes, and most applies Assurance Case regime for many industrial domains. USA, Australia and EU countries apply Assurance Case approach for safety and security regulation and licensing. For the last two decades Assurance Case has been used mostly for confirmation analysis of critical systems with established set of regulatory requirements. There are proven standards of use, notations and tools to support Assurance Case methodology. However, many researchers have tried to find approach to expand Assurance Case application to communicating domains. We group the following directions of Assurance Case applications as the following ones: Assurance Case for attributes assessment such as quality, dependability and, first of all, safety and security, Assurance Case based certification, improvement of argumentation, assurance based development, and Assurance Case for knowledge management. The main challenges and solutions of development and application of Assurance Case methodology, techniques and tools have been analyzed.
Highlights
Assurance Case (AC) is a reasoned and compelling argument, supported by a body of evidence, that a system, service or organization will operate as intended for a defined application in a defined environment [1]
Regulatory authorities and other stakeholders of licensing processes recognize benefits of AC implementation, since AC increases the depth of study by gathering evidence of safety and security from a range of sources including risk assessments, incident
The AC regime is a means of establishing a formal structure for safety and security related activities and ensuring that a disciplined and standardized approach to managing risk is adopted
Summary
Assurance Case (AC) is a reasoned and compelling argument, supported by a body of evidence, that a system, service or organization will operate as intended for a defined application in a defined environment [1]. Regulatory authorities and other stakeholders of licensing processes recognize benefits of AC implementation, since AC increases the depth of study by gathering evidence of safety and security from a range of sources including risk assessments, incident. The AC regime is a means of establishing a formal structure for safety and security related activities and ensuring that a disciplined and standardized approach to managing risk is adopted. In many critical industries, such as nuclear energy, aviation, defense, etc., AC (or Safety Case) is required by the regulator to establish the safety and security of systems or activities. The USA, Australia, as well as European Union develop and apply AC approach to safety and security regulation and licensing. Which provide well described industrial cases, for example [2] It is worth considering additional application of AC. In this paper we study, how AC can add value to other activities and applications, which are only partly related to regulatory issues
