The development of a program is a process thatconsists of a number of separate operations, but in the end, the user will directly interact only with visual data. Thus, the program interface is the conductor between the client and the proposed functions. Therefore, the design must meet all the necessary requirements, otherwise the program's capabilities will not be evaluated.
The design of the program interface should not beless time than writing the main code, so you should not forget about this part of the development. You need to consider it when discussing the timing of the performance of an order. In addition, the creation of a management system should be carried out simultaneously with the development of the functional part of the program.
The program interface appears due toa work process that can be divided into separate tasks. The first stage of development is an analysis of the activities that the user will perform to achieve a specific result. In accordance with this, test models are created and it is determined whether the customer's actions meet the specified requirements. After the experimental part, some changes are made to the development, the future interface of the program is supplemented with missing elements. Then the final version of the prototype is selected and after the creation of the test version the result of the work is coordinated with the customer. If necessary, the work includes the creation of training documentation.
Thus, the development of the user interfacemust end with the creation of a menu. They should provide quick access to the main functions of the program, as well as respond to a large number of visual requirements. When developing, you must consider all the details that can affect the behavior of the person using the program windows. The graphical characteristics of the interface include the effect of a combination of colors, the correspondence of fonts and the size of the pin to the task. It is also estimated what impression the overall appearance of the program in general, whether it meets the requirements of a harmonious composition and whether the user will want to return to work with this program.
All these requirements can be characterized by oneterm - usability, which is one of the main criteria for assessing quality when creating a program interface. The level of usability is defined, as in all matters relating to ergonomics, indicators of efficiency and productivity.
You can identify the main objectives common todevelopment of any user interface. A quality interaction environment should provide time savings in the process of searching for the necessary information, selecting and assigning a specific team. When using a decent interface, the productivity of a person for a given period of time will increase. At the same time, if the client does not get tired or feel uncomfortable with prolonged work in one environment, then one of the main tasks of the interface developer has been professionally accomplished.
