To do this exercise we basically took a set of samples which consists of several domain people including system developers, web experts and others. These population is drawn from many organizations who work on the development paradigm. We ultimately found that the case principles have good impact on design of the web applications. The results ensure the improvement of the quality of the designs and functionality. This is found to be an effective designing of web applications.
