2. What is Agile Software
Development?
It is a method of Software development
where the problems and answers to a
development is found through
collective, self organizing cross
functioning team members.

3. Agile
Software
Development
There are three main phases :
 Requirements planning
 Design workshop
 Implementation
There may be several other sub steps to merge to a one.
but mainly there are three steps to follow.

5. Agile Software Development :
 Is a rapid way to develop a computer application.
 Is use to develop both Desktop and web-based
applications
 Is an object development approach
 Is use several tools to implement a good product.
 Is a way which customer also can involve.

6.  The concept of RAD are:
 To more actively involve system users in the
analysis, design and construction activities
 To organize systems development into a series
of focused, intense workshops jointly involving
system owners, users, analysts, designers and
builders
 To accelerate the requirements analysis and
design phases through an iterative construction
approach
 To reduce the amount of time until the users
begin to see a working system
 To use prototypes to their fullest potential

TEAM WORK
Extreme Programming emphasizes teamwork.
Managers, customers, and developers.They improves a
software project in five essential ways: communication,
simplicity, feedback, respect, and courage.
“As developers we need to remember that XP is not the only
game in town.”- Pete McBreen

9. WhyThis ?
Benefits:
The Higher traction, because Aglie offers,
• Improved quality
• More opportunities for mid-course corrections
• Improved customer or business satisfaction
• Better alignment between business & IT
• Improved time to market.

10. Why this?

11.  The benefits of RAD are:
 Useful for development where the requirements are
unpredictable
 Increases end-user enthusiasm and visibility due to active
involvement
 Users and management see working, actual solution outputs
rather than conceptual designs more rapidly than in Model-
Driven Development
 Errors and omissions tend to be detected earlier in
prototypes than in system models
 Testing andTraining is a natural by-product of the underlying
prototyping approach
 The iterative approach is more “natural” fit because change
is an expected factor during development
 It reduces risk because you test the technical solution
iteratively instead of making a wholesale commitment to
any solution
Why this?

12.  Disadvantages
 Active user involvement and collective efforts
are required all through out the development
process.
 New requirements may arise or change while the
development is going on.
 Miscommunication between team members
may cause an improperly developed software.
 Because testing is done while developing, the
finished product may have higher chances for
errors.
