Revision Standard - Active. ISO/IEC/IEEE 15026-2:2022 specifies minimum requirements for the structure and its meaning of assurance cases. It does not place requirements on the quality of the contents but describes the structure and its meaning of assurance cases with the necessary level of precision and detail so as to avoid inconsistent and subjective use of the terms. While several notations and slightly varying terminologies are currently used in practice, this document does not require the use of any particular concrete representation including graphical representation. Likewise, it places no requirements on the means of physical implementation of the data; in particular, it includes no requirements for redundancy or co-location.
