"Rolling Wave Project Planning (RWPP) is a phased iterative approach to project development, applicable to new product development, information systems and other technical development environments. It is an excellent formal project development approach for inventive work. When done well, it balances structured process with flexibility. It is appropriate for project life cycle models/methods that allow incremental development (spiral, evolutionary prototyping, etc.)."
