It is suitable for a smaller project where needs are well understood. Simple, easy to understand and use. For example, if the project makes use of software or technologies with very rapid release-cycles and paces-of-change, then the project needs to have fixes being implemented on a monthly basis. New developers can get up to speed quickly – even during the maintenance phase. Multiple development cycles take place here, making the life cycle a “multi-waterfall” cycle.
