3. 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

4. ● 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

16. 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.

17. 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.
