ISO/IEC TR 20000-5:2013 is an exemplar implementation plan providing guidance on how to implement a service management system (SMS) to fulfil the requirements of ISO/IEC 20000-1:2011. The intended users of ISO/IEC TR 20000-5:2013 are service providers, but it can also be useful for those advising service providers on how to implement an SMS. ISO/IEC TR 20000-5:2013 includes advice for service…

ISO/IEC 15026-1:2013 defines assurance-related terms and establishes an organized set of concepts and their relationships, thereby establishing a basis for shared understanding of the concepts and principles central to all parts of ISO/IEC 15026 across its user communities. It provides information to users of the subsequent parts of ISO/IEC 15026, including the use of each part and the combined…
