The Heads of all IT outsourcing enterprises understand that to be competitive in the computer programming market one has to deal with software development methodologies. Here comes the question:

  • What is a software development methodology?
  • What for do we need to use software development methodologies?

A software development methodology is a complex of processes, rules and procedures executed by a development team and the whole outsourcing enterprise employees to achieve the main goal of web development: high-quality software.

Here are the benefits of using software development methodologies:

  • Number of defects is reduced;
  • The project is ready in less time;
  • Improves created software quality.

And now it’s time to tell what software development methodologies exist. I guess the best way not to waste time of the web developers (and all other readers of the following article) and list only up to date methodologies. They can be divided into two groups:

  • Engineering methodologies (plan-driven methodologies is another name of the group)
  • Agile methodologies

Engineering methodologies

The core of these methodologies is software production based on non changing specification. Rational Unified Process (RUP) is the most often used engineering methodology.

Agile methodologies

The main core of the agile software development is in adapting the process of product construction throughout its life cycle. During agile software development the project can be easily adjusted to custom changes throughout its development.

Extreme Programming (XP) and Scrum are the most often used methods of agile development.

As a conclusion I have to admit that that it’s up to you to decide whether invent a new software development methodology or use an existing one. But there is no doubt that a software development methodology should be used.
