So does the environment.

We are uncovering better ways of developingsoftware by doing it and helping others do it.Through this work we have come to value:

Individuals and interactions over processes and toolsWorking software over comprehensive documentationCustomer collaboration over contract negotiationResponding to change over following a plan

That is, while there is value in the items onthe right, we value the items on the left more.

Some of our work goes down the drain

Most of time it's almost ready

We lie to ourselves

Customers will understand

We will fix it in the next release

Efficiency deterioration

Continuous attention to technical excellence and good design enhances agility.


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

Individuals and interactions over processes and tools

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

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

Responding to change over following a plan

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

Customer collaboration over contract negotiation

Our highest priority is to satisfy the customerthrough early and continuous deliveryof valuable software.

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

Business people and developers must work together daily throughout the project.


Working software is the primary measure of progress.

http://agilemanifesto.org/

Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.

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

http://agilemanifesto.org/

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