How to use it
 
Boiled down to its essential characteristics, Agile happens in teams, and it is about adapting to new information, rather than executing a pre-ordained plan. The main hallmarks of these fast-moving teams:

Customer involvement
Teams develop an evolving prototype that allows them to enter a dialog at early stages in the process where they can receive repeated feedback from customers.

Iteration
Teams work fast, dividing larger tasks into smaller chunks, and then perform cycles of building and testing to learn quickly from incomplete prototypes – these cycles are often called Sprints. The goal of each cycle is to create a deliverable/prototype that receives customer feedback.

Learning 
Each team, and the organization at large, reflects on past projects and digests this information. Reflection enhances organizational learning, improves processes, and builds trust/creates better relationships with stakeholders.
