I think Qs to ask are.. if the nature of user facing deliverable tasks are longer than a sprint, the tasks have linear dependencies, there are coordination concerns, etc
Sprints are just ritual though. The others... if you're that low I'd say you're past waterfall since you have well defined tasks.
