There are three different types of assessments used in this document.
**Conceptual assessment**, where documentation on the products assets and external capabilities and claimed mechanisms is compared with the applicability requirement’s text. This style of assesment is kept in minimum.
**Functional completeness assessment**, where verification that the claimed mechanisms cover all interfaces and functions where the feature is required by the standard and the product’s use case. Often the output is required to show proof of the implementation exactness.
**Functional sufficiency assessment**, where it is addressed in the assessment of appropriateness to evaluate whether the requirement implementation is adequate for their intended purpose. This is used with for example system architecture description, where using quantitive metrics would be unreasonable.
