Software Development Life Cycle
Choosing the right software methodology is crucial to successfully create new software. There are two prominent approaches to this. The first is the Waterfall methodology, which is a traditional and linear approach to software development, meaning that each new stage may only commence following the successful completion of the previous stage.
The other main methodology is Agile, which is more flexible and can lead to rapid deployment. Agile breaks up a project into short, iterative cycles known as sprints that can be completed in any order, thus allowing for frequent adaptation and improvement. Agile allows for quicker delivery, reducing the time to market.
The SDLC consists of four stages, as illustrated in Figure 23.1:

Let’s now look at each of these in turn.
As shown in the diagram, the first stage is software development. It is important to use the most...
