Agile Manifesto
We are uncovering better ways of developing software by doing
it and helping others do it. Through this work we have come to
value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, 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.

Agile Principles
 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.
