Chapter 6

Overview

The following provides an overview of the waterfall life-cycle development methodology and the associated testing activities. Deming’s continuous quality improvement is applied with technical review and testing techniques.

Waterfall Development Methodology

The life-cycle development or waterfall approach breaks the development cycle down into discrete phases, each with a rigid sequential beginning and end (see Figure 6.1). Each phase is fully completed before the next is started. Once a phase is completed, in theory during development, one never goes back to change it.

In Figure 6.1 you can see that the first phase in the waterfall is user requirements. In this phase, the users are interviewed, their requirements are analyzed, ...
