However, this model is suitable only for well-understood problems; it is not suitable for very large projects and for projects that are subject to many risks.

What type of projects is rad best suited for?

RAD is especially well suited for (although not limited to) developing software that is driven by user interface requirements. Graphical user interface builders are often called rapid application development tools. Other approaches to rapid development include the adaptive, agile, spiral, and unified models.
