We estimate juzabiliti

The term "juzabiliti" today became extraordinary popular. Him  hhegoljajut everyone, to whom not laziness. And many of those who uses this word, actually have only vague performance about his  value. Whether it is necessary to speak, what such people are not capable to estimate correctly juzabiliti the web - project? And therefore it is not absolutely correct at creation of design of a site to lean{base} only on results of his  testing by usual visitors. Meanwhile in most cases and the web - project for increase in convenience of his  use "is run in". And how it is necessary to do{make} it correctly? Let's try understand this question.

To start it is necessary that juzabiliti the web - project the present{true} expert in this area can give a competent rating only. Only, to our big regret, the Russian educational establishments do not hurry them to prepare. It in the western countries juzabiliti teach not only on every possible rates, but also in VUZ'akh. Also it is completely correct approach. In fact, for example, the instrument panel of automobiles is developed by experts, but in any way simple drivers. So why with websites of an affair should be in another way?

But let's better return to our realities. In Russia to find the qualified expert on juzabiliti it is practically impossible. Though, certainly, if very{very much} to try to make all this-taki really. Only the representative of so scarce trade will take rather significant sum for the job. And therefore to count on the help of professionals to the majority of web designers it is not necessary. In this case it is possible to lead{carry out} replacement. It is the best way to invite instead of diplomaed experts of experienced users of the PCs training other people. They fine know, what exactly causes questions and difficulties in their wards. Well and behind absence of such users, it is possible to use services of other people. The main thing that they were skilled enough and unbiassedly concerned to the given web - project.

The following step in carrying out of research juzabiliti the web - project - a choice of a method. For today the greatest distribution was received with two ways of a rating. First of them - heuristic. The essence of it  consists in the following. The expert considers{examines} each element of the interface of a site separately and estimates it , leaning{basing} on the special list of the certain principles juzabiliti, "ehvristik". The given method can be named safely "nepersonizirovannym" as at his  use from the person and his  personal sight the little depends.

The second method of a rating juzabiliti - expert. His  essence consists in the following. Job is conducted at once by some experts. The set is given each of them corrected, principles and preferences to which the design of a site should follow. Then each of experts estimates juzabiliti elements of the interface not in comparison with ehvristikami, and on the basis of given to him the owner of the project of the information. Usually expert method allows to achieve more exact results of research. All the same, in some cases use for a rating juzabiliti ehvristik is not absolutely successful, as they do not take into account specific features of the project, users for whom he is designed, etc. Thus, the expert method has serious advantage before heuristic. However is at him  and not less serious lack. The question is "personification" of a rating. If the owner of the project will be mistaken with a choice of experts can receive incorrect results. Unique protection against it is attraction to researches at once several the person, which will carry out testing separately from each other then to average the general{common} ratings. To tell the truth, it will be poured out in additional expenses, that in many cases too it is undesirable.

So, how carries out research juzabiliti a site? Experts for the beginning get out and are invited to job. The full information under the web - project is given out to each of experts: the decided{solved} purposes and the problems{tasks}, prospective structure of an audience, principles and the rules pawned in a site by founders, and also criteria on which it is necessary to estimate. After that each expert separately from others works with tested system. And it is necessary to give to experts enough time that they could it is high-grade will familiarize with a site, and not just " to be run on tops ". During research experts put down ratings by various criteria, and also write down all revealed problems. After all researchers have finished the job their results it is necessary "to average". Thus, we shall receive the most exact rating juzabiliti. As the report the list of the found problems sorted on decrease of their gravity and importance for the given web - project is usually used.

For today the greatest distribution was received with two ways of a rating juzabiliti: heuristic and expert

And now give we with you, dear readers, we shall answer one more question which rises web designers: when to carry out researches juzabiliti a site? Overwhelming majority of people do{make} it directly before start of the web - project. However this incorrect decision. In fact if the site is completely ready, and in him there are serious lacks it is necessary to send it  for processing. And it is poured out in additional expenses as money, and time. Also all terms are already broken, and process of creation is beyond the planned budget. That it has not taken place, testing juzabiliti should be spent at earlier stages.

Experts advise to spend examination juzabiliti some times. However frequently owners of sites do not presume it. In that case, by the most successful variant happens testing during creation of design. And it is valid, at this stage all basic lacks can be revealed. Well and to correct them too it is possible. However it is impossible to forget, that juzabiliti a site is not only used color circuit and a set of elements of the interface. Very big role in juzabiliti the system of navigation under the web - project, the organization of the catalogue (it is very important for Internet - shops) and plays the other similar moments. Therefore the rating juzabiliti is desirable for spending even twice: at a development cycle of design and during creation of structure of a site and filling by his  content. And to neglect this part of job above the web - project in any way it is impossible. Yes, certainly, all lacks can come to light and during the first months of job of a site. However for this time it is possible to lose for ever many visitors and potential clients. As right after opening serious marketing campaign is usually spent. If in juzabiliti a site there are serious lacks the money spent for advertising, can appear thrown out not a wind.
