This document presents an overview of agile methodology. It begins with definitions of agile and compares the waterfall and agile approaches. It describes the agile lifecycle and includes a graphical representation. The agile manifesto values and principles are outlined. Key characteristics of agile include breaking tasks into small increments with minimal planning and using short iteration cycles with cross-functional teams. Techniques like pair programming, continuous customer feedback, whole team involvement, and daily standup meetings are discussed along with their pros and cons. Limitations and a conclusion praising agile flexibility are also provided.

(Merriam-Webster 2002)

5. Waterfall Vs Agile Approach

6. Agile Lifecycle

7. Graphical Representation

8. AGILE MANIFESTO VALUES
● V1: Individual and interaction are valued over process
and tools
● V2:Working software is valued over comprehensive
documentation
● V3:Customer collaboration is valued over contract
negotiation
● V4:Responding to change is valued over following a
plan

9. AGILE MANIFESTO
PRINCIPLES
● P1:Customer is the highest priority
● P2:Welcome changing requirements , even late in
development
● P3:Deliver working software frequently
● P4:Bussiness people and developers must work
together daily throughout the project

10. ● 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 from self-organizing teams.

11. CHARACTERISTICS
● Agile method break the task into small increments
with minimal planning
● Iteration is a short time frame
● Each
iteration involves a cross-functional team
working in all function
● Each agile team must have customer representative
● Most of the agile methodology use daily face-to-face
communication

12. Techniques of Agile
1. Pair programming-

13. 2. Continuous Customer Feedback-

14. 3. Whole team involvement-

15. 4. Daily stand-up meetings-

17. 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.

18. 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.
