1. INTRODUCTION TO AGILE

● “Everything Should Be Made As Simple As Possible

But Not Simpler” -Albert Einstein

● “Core to agile software development is the use of light

but sufficient rules of project behavior and the use of

human and communication oriented rules.”

• -C . Burn

● The term agile can be defined as-

1) ability to move with quick easy grace, or

2) having a quick resourceful and adaptable character

(Merriam-Webster 2002)

● An iterative and incremental (evolutionary) approach

performed in a highly collaborative manner with just the

right amount of ceremony to produce high quality software

in a cost effective and timely manner which meets the

changing needs of it’s stakeholders.

● P1: Customer is the highest priority

● P2: Welcome changing requirements , even late in

development

● P3: Deliver working software frequently

● P4: Business people and developers must work together daily

throughout the project

● P5: Face-to-face conservation is the best communication

method

● P6: Working software is the primary measure of progress.

● P7: Agile process promote sustainable development.

● P8: Continuous attention to technical excellence and good

design enhance agility.

● P9: The best architecture , requirement , and design emerge

8. Limitations

● The agilest have not clearly defined the context for their

statements.

● Agile Manifesto and literature concerning agile software

development have not thoroughly discussed the use of

software tools and their role in agility.

● When software development is performed by several parties,

more pressure to communication and coordination emerges.

9. Conclusion

Most frequently changing thing in software development field

is customer requirements which keep on changing with in fraction

of second. Hence it become very difficult for developer to cope up

with continuously changing requirement. In today’s cut throat

competition it is very important to satisfy your customer , if you

are not than you are out of the race.

So in this environment Agile methodology is panacea to all. It

provide flexibility to customers that they can change their

requirement at any point of time according to their ease and this

change is not a matter of worry to developers. In nutshell , Agile

methodology rejuvenate conventional process of software

development.
