Chapter 30. RAD Process Elements Explained
Principles of RAD
RAD processes are built on the principle that a date is set in the calendar and will not move. The development effort is then tailored to the available period of time. Delivery dates are often set at regular intervals, such as monthly, every 6 weeks, every quarter, and so forth. The intervals are usually short—otherwise it wouldn't be called “rapid” application development.
The foundations of RAD can be explained in TOC terms. RAD sets the delivery date, or project timeline, as the system constraint. With the delivery date as the constraint, everything else is then subordinated to it. Hence, the other main constraints in the system must be protected and exploited to meet the delivery ...
