It defines Generic Conditions (such as “Task” or “Stakeholder”) that need to be specifically defined in other statements - that reference the Scale specification, such as Past or Goal.
For a given Scale, any useful number of Scale-Qualifiers can be defined.
Scale-Qualifiers are Generic; each Scale-Qualifier needs to be explicitly assigned a corresponding “Scale-Qualifier-Definition (unless a Default is being used) when the Scale is used in other Parameter statements (such as any Benchmarks or targets).
1. A Scale-Qualifier is expressed and signaled by enclosing it in (optional, but useful signal) square Qualifier brackets. The word “defined” is optionally specified immediately prior to the square brackets or Scale-Qualifier term, to help emphasize that a more specific definition needs to be defined when the Scale is referenced, for example by a Goal statement.
2. A Default option can be specified in order to make explicit specification unnecessary.
3. The Scale-Qualifier Parameter can also be “referenced” by using the same sequence as used in the Scale definition: Note in this example, an additional Qualifier Condition, not in the original Scale definition, has been added. This is OK. You can Add any number of additional Conditions that you want.
4. The sequencing of Scale-Qualifiers and Scale variables is not critical as long as the Parameters are unambiguous to the specification user.
