scope:

This document specifies requirements for the structure and meaning of assurance cases. It does not place requirements on the quality of the contents but describes the structure and 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. This document is intended to be utilised while developing and maintaining assurance cases.
