Prestwood Software Development Process™ (PSDP) is a proven process that features scalability and flexibility geared toward managing the development of software systems, applications, components, web sites, and web applications. PSDP is an iteration-centric full life-cycle software development process. Iteration, as defined in PSDP, is a deployed version of the software to the end users. A project usually contains one iteration of the software and that version is usually numbered 1.0, 1.1, 2.0a, etc. Although PSDP is iteration-centric, it does offer mechanisms for enterprise modeling, multiple iterations, and the maintenance that occurs between iterations.
