Agile Manifesto for Software Development.

The principles behind the way we work

The Agile Manifesto was devised in 2001 because there was a need for an alternative to document-driven, heavyweight software development processes. We abide by the manifesto, and our projects are a success because of it. It says that:

We are uncovering better ways of developing software by doing it and helping others to 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.

Principles behind the Agile Manifesto

We follow these principles:
1
Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
2
Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
3
Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
4
Business people and developers must work together daily throughout the project.
5
Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
6
The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
7
Working software is the primary measure of progress.
8
Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
9
Continuous attention to technical excellence and good design enhances agility.
10
Simplicity — the art of maximizing the amount of work not done — is essential.
11
The best architectures, requirements, and designs emerge from self-organizing teams.
12
At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
