Specific metrics
Specific metrics are often defined as a relationship between two General metrics, such as the number of serious issues divided by the number of requirements. The name of a Specific metric can contain the word frequency or density to show this relationship. Specific metrics can also be defined as a single relationship (not a quotient), such as the number of Unused abbreviations.
A measure is defined as an operation for assigning a number to an object. During analysis, the program measures the number of serious issues for a Specification. A metric is the interpretation of the assigned number. The metric Unused main actors is interpreted as the number of Actors that were defined but never used in the Specification. When a measure is applied, the number obtained is a measurement, for example the value 5.
