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.

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.

This process can be Repeat until the Customer Satisfaction

But There are No Time to Waste….We need to hurry!

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.

Nature of ASD


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 WORKExtreme Programming emphasizes teamwork. Managers, customers, and developers. They improves a software project in five essential ways: communication, simplicity, feedback, respect, and courage.

Why This ?

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.

Why this?

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 and Training 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?

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.
