Commonality by request count. Compare the result and its obtaining conditions; repeated wording is not a family.

The primitive is the offering. Add the delivery, acceptance and continuing responsibilities needed to provide it.
Admission fields instead of construction. Build a member, a changed-condition case and a support arrangement before judging admission.
