In what case is one justified in using the horrible phrase “use case” instead of the single word “use” by itself or the single word “case” by itself or the single word “when” by itself, as the advisable case may be? Or is the horrible phrase “use case” merely a case of jargonic flabbiness that writers use only because they’ve seen it?
Compare: “When do you need to plug the cord into the outlet? Only when you need power?”
To: “What use cases require plugging the cord into the outlet? Is it only the power-needing use case?”
Compare: “Oh what’s the use! I can’t go on!”
To: “Oh what’s the use case! I can’t go on in this use case!”
