Agile software development processes support the continuous delivery of working software. The agile software development process continuously adds value to the business.

• Agile development builds Software in highly structured mini-projects.  The geek name for such a mini-project is an iteration.  An iteration normally lasts two weeks.
• Every iteration aims to deliver one or more features.
• A feature is useful, usable, production ready software.
• A feature is small enough to describe easily and is a unit that a user can actually use in their normal work.
• A feature might automate part, or all, of an existing process allowing a user to work faster, work more accurately, or concentrate more energy on the parts of the job that need brain power and deliver higher added value.
• A feature might be new functionality allowing a user to do things they could not do before.
• Users should begin using new features, in production, adding value to the business by doing their jobs, faster, easier, or doing things they could not do before.
