Web application development-Methods of development

Web application?

We create web applications, that is to say, software designed to be used from a web browser like Internet Explorer, Firefox or Safari. One advantage of such software, compared to conventional software is that it requires no installation on your computer. You can use it to wherever you want; same from your phone. A web browser acts as a client and there is a server side on the web to handle the complete database interaction

Conventional methods

If you see a big consulting firm, here is the classic scenario:

You will jointly undertake the development of your needs, and the firm will undertake to write a document describing everything the application needs to do (functional specs). You will sign a contract (very expensive) which confirms that it is this application you need. Then you will lose sight for a while, and they will return with an application that meets the needs identified during the preliminary study.

It is seen in most cases that when this application is delivered, the customer often feels he had missed something during the preliminary study, simply because he could not see or touch software before receiving the final version. To add any extra features required an extra expense for the customer which led to an application costly and poorly responsive to its needs.

Agile development

This is the new way of developing web applications . It follows a much more interactive approach towards the development life cycle..

ith the initial requirements basic schemas are developed, and the application starts to be developed. The work is divided into iterations as small as possible. Each iteration is a cycle that adds functionality to the software, which works even if it is already far from being completed. After each cycle, the result is evaluated by the customer to ensure that the direction in which the development is moving is good. Any changes required are then made at that particular level.

The result is an application that meets the needs of the customer.
