Operation not called (Reviewer Review)
The operation is not used on a sequence diagram.
Consequences
How the operation is used is not obvious to developers.
The operation may be redundant.
Strategy
If the operation is necessary and non-trivial it should be shown on a sequence diagram to help define functionality.
Some operations are trivial and necessary, in which case ignore this review item.
If the operation is unnecessary consider removing it from the design.
