Yuzabelnost and interface

Modern operating systems remind quest, than the intuitive software product with accurate assignment more. Right after a release of OS to the public, on shelves there are dozens of books how to survey all its functionality what tricks and secrets in relation to it can be applied, on social networks series of videos with reviews instantly appear, logs have a set of subjects for publications. But so was not always. Let's remember the old ancestor of Windows - DOS Shell. He did not differ in big functionality. There was a time, Windows is developed, become more functional, more interesting, more difficult, more various. In the companies which are engaged in development there are not only programmers and sales managers as can seem at first sight. An integral part of these firms are testers, thanks to them programs and operating systems become not only functional, but also convenient for use. The product pokupayemost also depends on them. For example, the large developer devotes much time on the analysis and testing of the software product, as a result it is pleasant to the user in view of its "yuzabelnost" (so in IT circles the property of a product when use of it does not cause additional problems is called), and small is not able to afford to pay work of additional employees, writes programs quickly, not always qualitatively, leaves everything as it is, as a result the program performs the functions, but people especially do not like, in other words, it not "yuzabelna". It follows from this that the user, most likely, will select that to him it is intuitive, most often he is interested in a name of the developer a little. In order that the program or OS became clear and convenient, the clear and convenient interface (cover, the toolbars) is necessary. Not captious user can cause, of course, a window of the help and read as it is necessary to be controlled with the program, but it long and sometimes difficult for understanding. Let's review an example from the 3D sphere - modeling. Let's compare 2 companies and their software products: Siemens and Ascon (Solid Edge and Compass). Siemens was always famous for the convenient interface when you create the project in Solid Edge, it is possible, without reading instructions and books, it is easy to understand where what button how to turn model, but is present also a shortcoming: the user beginner not always at the output receives that model that conceived. Askon was never famous for the friendly interface to remember where in the Compass there are panels and buttons, it is necessary to spend time, but functionality such idle time that at the output we always receive that we conceived. The only sphere where the accent always goes on convenience of the user, is computer games because, unlike programs, there is no need for their use, that is will buy only the most convenient and interesting. Recently most the companies begin to pay attention to a yuzabelnost more, it cannot but please.
