Traditional Methods Of Software Development

There are two types of Software Development Life Cycles: Traditional and Agile. There are three main traditional methods of software development. They are: the Waterfall model, the Spiral model and the V- model.

Waterfall Model:

The Waterfall model is called so due to the fact the model flows in a downward fashion to the next process. There is usually a review after each phase of the model. The process of the model is as follows.  More info can be found here.

Spiral Model:

The spiral model is based on the whole idea of the customer giving constant feedback. This model works in a spiral linear method. Each phase goes through a spiral of processes called “iterations”. See below for the phases in the spiral model. More info on the spiral model here.

V-Model:

The V model is similar to the Waterfall in the way each phase must be completed before moving onto the next. However testing can be on-going as opposed to after each stage like the Waterfall model. See diagram below. More info here.
