Conclusion

IntroductionIn general, unlike traditional linear (waterfall) development,

Agile methods seek to break down organizational barriers and drive toward faster incremental development and

deployment, without compromising the quality of the delivered product. Agile is focused on individuals and interactions over processes and tools, yet contrary to some (widely

held) beliefs, “true” Agile Development is extremely structured and disciplined, and typically will only succeed in higher maturity organizations

History of the Agile Methodology? The modern definition of agile software development evolved

in the mid-1990s as part of a reaction against "heavyweight" methods, perceived to be typified by a heavily regulated, regimented, micro-managed use of the waterfall model of development. The processes originating from this use of the waterfall model were seen as bureaucratic, slow, demeaning, and inconsistent with the ways that software developers actually perform effective work. Initially, agile methods were called "lightweight methods.“

In 2001, 17 prominent figures in the field of agile development (then called "light-weight methods") came together at the Snowbird ski resort in Utah to discuss ways of creating software in a lighter, faster, more people-centric way. They coined the terms "Agile Software Development" and "agile methods", and they created the Agile Manifesto, widely regarded as the canonical definition of agile development and accompanying agile principles. Later, some of these people formed The Agile Alliance, a non-profit organization that promotes agile development.

What Is Agile Methodology?Although there are many differing approaches to Agile

Development, there are a number of shared characteristics that generally apply. These are:

Agile Development Methodology is an approach to software development that values early and continuous delivery of production ready software in a structured, systematic and repeatable wayAt its core, Agile focuses on the efficiencies that are natural to small teams that have well defined roles and responsibilities. The goal is to have a process that enables the highest percentage of project effort to be spent on building quality components while avoiding all extraneous stepsFrequent delivery of proven production ready software is the single most important measurement of progress

Development iterations that are most typically between 2 and 6 weeks in lengthoStrict adherence to:

Iteration start and end dates Iteration deliverables which include (not

necessarily in this order) Requirements gathering and analysis Planning Design Development/Build Testing Deployment Documentation

Delivering production ready software (iteration end dates are not milestones)

Agile Methodology, cont.

Embracing requirements changes at all times during the project but locking requirements once they are included in an iteration

Using each completed iteration as a mechanism to reprioritize business requirements

Continuous face-to-face interaction with requirements drivers whether they be clients, business partners, or subject matter experts

A common theme among team members, which strives for the most simplistic solution to a given problem. These typically focus on specific problems which are real today and do not attempt to address problems which may occur in the future.

Continuous re-evaluation of the methodology, the procedures, the code. Everything should be frequently re-evaluated for inefficiencies and updated to reflect the current team, department, company, and industry environments.

Deliver working software frequently

Work together

Build projects around motivated individuals.

The Agile Values

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

• 1Individuals and interactions over processes and tools

• 2Working software over comprehensive documentation

• 3Customer collaboration over contract negotiation

• 4Responding to change over following a plan
