... systems may require more iterative development models. More complex models have been developed and successfully used to address the evolving complexity of advanced and sometimes large information ... Examples of these more complex models are the rapid application development (RAD) model, the joint application development (JAD) model, the prototyping model, and the spiral model. The expected size ... thus advancing the business application and security requirements together to ensure a balanced approach during development. Figure 3-1, organized by development phase, provides an overall view...
