Usability plays a very important role in determining the efficiency of a website, and suggests the ability of the node to use the website (Neilson, 2001). It is a quality component and determines the easiness and the convenience in use the website (Neilson, 2003).The guest should take chances the website user-friendly and interesting (Neilson, 2001). In this article, the importance of usability to websit es is mentioned, but it could be applied to any area. As thither are countless number of websites providing pertinent nurture, people possess several options. Hence, if a website is badly designed, it would deliver from not being visualized by the node. The customer has to be involved during the construction stage itself to pick up that the website can be designed in the around appropriate manner.Another fact which should be noteworthy in this regard is that a customer would not return to the website if it is bad, as a negative fancy would already have been generated in the mind (Neilson, 2001). Before the website is launched, a sample of the potential customers should result feedback. Studies have shown that these potential users have provided appropriate feedback which was utilized and helped to improve the quality of the website. Many web-designers have made huge amount of corrections within a very short period of time, and with a little enthronisation after taking ad vice from the sample of the customers.Usually customers were lost right from the start of the homepage, were a registration of the customer was required (Neilson, 2001). Usability is likewise required for the website surviving in the market. Customers would leave the website at any given point of time, if it is difficult to use. Any information put in a difficult to read manner would also have the same consequence. It is very important that the website answers the questions of the user promptly (Neilson, 2003). Hence, the information presented should be very relevant and specific.In the industry of web designing, usability suggests that the designers are very efficient at the construction of a website. At the moment about 10 % of the construction of websites costs is spent on determining and improving the usability (Neilson, 2003). It is one of the areas a website production unit would be spending more compared to other quality areas (Neilson, 2003). There are several criteria for assessing usability. These include- 1. Efficiency The ability of the user to perform the activities mentioned, once they have learned the website.2. Learnability The ability of the user to perform the activities easily, once they are able to enter the website. 3. Satisfaction The pleasure derived in using the website. 4. Errors The chances of committing errors on the website, and the extent of these errors along with the ease in which they can be corrected. 5. Utility The ability to perish in an appropriate user-friendly manner, (Neilson, 2003). 6. Accessibility The customer should be provided with access to appropriate information in the website.This is one of the most important criteria a website should follow (Lynch and Horton, 2002). 7. User-friendly design The graphics and the texts available on the website should be balanced and prepared in a well-balanced manner. It should encourage good flow of information. The website should provide content and should be user-friend ly for only the target audience group. The navigation aids present on the website should be accessible. Sometimes, the user may require additional information, and in such circumstances an access touch on should be available.This access links should always be functional (Lynch and Horton, 2002). 8. Relevant information The website should provide relevant and current information. Sometimes, further details about the source from where the information is derived, would also be required. 9. Authors name and the Credentials of the author The website should be providing the authors name and the credentials of the author, so that the customer can also weight the accuracy and genuineness of the information provided. Judgments to improve the usability should be made by the potential customers.They should be called in at the designers office. The correction would be occurring in a process, which include- 1. Determine the objectives and the activities of the representative user At first, the users should be told the objectives of the website and they should be given sufficient information to proceed on to the next task. Each representative tasks should be written on a key page, and once the user finishes with one age, he/she could move on to the next page (Neilson, 2001). 2. The people testing the usability of the website should be placed in real-life instances.Their profile should suit that of the relevant audience the website wants to target. To test a busy site, 5 people should be utilized. The time each tester should spend ranges from 20 minutes to about 2 hours (Neilson, 2001). 3. The test sessions should be performed in a serene and a quiet environment. Usually, testing should be performed at one person at a time. However, if one tester cannot observe or discompose the other tester, the process can be done for several individuals at a time (Neilson, 2001). 4.The areas the testers put through certain difficulties should be observed immediately, and efforts should be made to correct them. The feedback and responses supplied by the testers is very important and should be utilized appropriately (Neilson, 2001). 5. Besides actually following the feedback and reactions of the user, several other issues can be sieve out by the designers to ensure that the usability of the website can be improved. Frequently, surveys may not convey precise information, and a lot depends on following the observations of the user.The information provided by a survey may frequently be misleading (Neilson, 2001). 6. During the process of testing, the designers should be quiet and observe what the representative user does or say. Anything said by the designers would affect the outcome of such a procedure (Neilson, 2003). Problems that could arise during testing- 1. The results obtained from one user may be similar to another user. In such a circumstance, it would be better to conduct the absolute procedure individually for each user or place them in rooms wher e one user cannot disturb another user (Neilson, 2003). 2.Frequently, the outcome of a testing may not be utilitarian if people not belonging to the target group are selected for testing. In such a circumstance, it would be better to select individuals (at least five of them belonging to the target group) (Neilson, 2003). 3. Users should not be told anything during the testing. Instead most of the talking should be done by the user. If too much talking is done by the testers, the users would get influenced, and real-life simulation would not be possible (Neilson, 2003).
