Agile Manifesto_____________
 
 - Individuals and interactions over processes and tools 
 - Working software over comprehensive documentation  
 - Customer collaboration over contract negotiation 
 - Responding to change over following a plan 
 
  While there is value in the items on the right, we value the items on the left
  more.
 
Agile Principles____________
 
Our highest priority is to satisfy the customer through early and continuous
delivery of valuable software.

Welcome changing requirements, even late in development. Agile processes harness
change for the customer's competitive advantage.

Deliver working software frequently, from a couple of weeks to a couple of
months, with a preference to the shorter timescale.
 
Business people and developers must work together daily throughout the project. 

Build projects around motivated individuals. Give them the environment and
support they need, and trust them to get the job done.

The most efficient and effective method of conveying information to and within a
development team is face-to-face conversation.

Working software is the primary measure of progress. 

Agile processes promote sustainable development. The sponsors, developers, and
users should be able to maintain a constant pace indefinitely.

Continuous attention to technical excellence and good design enhances agility. 

Simplicity--the art of maximizing the amount of work not done--is essential. 

The best architectures, requirements, and designs emerge from self- 
organizing teams. 

At regular intervals, the team reflects on how to become more effective, then
tunes and adjusts its behavior accordingly.
