You will hear us talking about web usability a lot. Why?
Web usability is an approach to make web sites easy to use for an end-user, without requiring her (or him) to undergo any specialized training. The user should be able to intuitively relate the actions he needs to perform on the web page, with other interactions he sees in the general domain of life e.g. press of a button leads to some action. The broad goal of usability can be:
1. Present the information to the user in a clear and concise way.
2. To give the correct choices to the users, in a very obvious way.
3. To remove any ambiguity regarding the consequences of an action e.g. clicking on delete/remove/purchase.
4. Put the most important thing in the right place on a web page or a web application.
