The simplest software model of evo delivery is a personal computer user building an application for himself interactively. The personal computer programmer then becomes the user, the setter of objectives, the analyst, the designer, the coder and the tester. There is constant iteration from the earliest stages as the system is built up. The iteration cycle is typically measured in minutes, not years. The system being built is real and evolving. Users can modify design, coding detail and even their final objectives.
Evolutionary delivery consists of a collection of many concepts. The more fundamental ones are listed below. Planners can choose to ignore some of them, but the method will lose some of its power if they do.
Planners may well find ideas additional to those mentioned here. I find that by experience and experimentation, I am constantly learning new ways to use the basic concepts better, and therefore do not pretend that the present model is complete. But it is more advanced than most models which I have found in the literature on the subject or in practice. Figure 7.2 illustrates three development models.
