Abstract

The current information processing speed is very high. To effectively manage a company, information should be speedily processed to make timely decisions at all hierarchy levels, from managers to executors. Information visualization in these conditions significantly speeds up these processes and reduces risks. The quality management system of a modern company includes elements and methodology of various performance improvement concepts, such as risk management, total quality management, lean manufacturing, six sigma, and the theory of constraints. The emphasis in process organization is placed on visual methods. Despite the fact that visualization as a method is considered within the concept of lean manufacturing, there are methods for representing information in a visual form defined in other concepts. The paper discusses the use of the methodology for information visualization in terms of different quality management system concepts. A comparative analysis of modern concepts for improving performance, an overview of the methodology designed to display information in the quality management system in a visual form is made, and successful examples of using various methods of information visualization for quality management in companies are given.
