Some methodologies have more than four. If there are only four, then they should be Requirements, Design or Blueprint, Build, and Implement. There are sometimes two more phases included such as Close-out at the end and Testing or QA after Build. Testing can be included in Build and Close-out in Implement. The Project Management Institute has good documents on all this at www.pmi.org
