Iterative Software Development

• Cycles through the development steps in small steps.
• Less rigidly defined steps, however they are still there (just quicker)s.
• Reaction to the previous methods.
• Goes back to the roots of software development.

Agile Values

• Individuals and interactions over process and tools.
