Operation not defined (Reviewer Review)
A non-abstract operation has not had its functionality defined.
There are two ways of defining functionality:
Content in the body field will define an operation.
Steps that are indented under the operation call on a sequence diagram also define functionality.
If the functionality of an operation is undefined it implies that the model is incomplete. This may lead to complications later in trying to establish what operations are supposed to do.
Define the operation on a sequence diagram.
If the operation is trivial and the description is complete then you may wish to ignore this review item.
