Agile Software Development

Why Agile?

James Shore and Shane Warden <ref>Shore, James and Warden, Shane. The Art of Agile Development. O’Reilly Media, Inc., 2008, p. 4.</ref> state that the benefit for developers to follow a Agile software development process is to deliver successful products to the client or customer. He defines success into 3 types:

1. Organizational
   • Deliver value and decrease costs to increase return on investment.
2. Technical
   • Elegant and maintainable code is produced.
3. Personal
   • Developers find the project fun and rewarding which lead them to be intrinsically motivated and devote passion to the work.

The Agile Manifesto

The Agile Manifesto is a set of 12 principles that provide a foundation for agile methodologies.

The core principles of the manifesto are as follows <ref>Manifesto for Agile Software Development http://agilemanifesto.org/ </ref> :

• Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan

Values

There are four concepts that represent the main values of Agile software development.

1. Adaptability
2. Transparency
3. Simplicity
4. Unity

Adaptability

Adaptability is purported to be the most important value <ref>The Agile Leader: Adaptability

http://blogs.forrester.com/tom_grant/11-04-19-adaptability_may_turn_out_to_be_agiles_most_important_virtue</ref> of Agile methodologies.

This value forces teams to plan for inevitable change in a mindful manner.

The focus for Adaptability can be summarized by these two principles stated in the Agile manifesto.

• "Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage."
• "At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly."

There are three components in Adaptability <ref>Adaptation in project management through agile http://searchsoftwarequality.techtarget.com/feature/Adaptation-in-project-management-through-agile</ref>:

1. Product
2. Process
3. People

These three components must ALL be open to change in order to have a fully adaptable agile environment.
