Ishikawa diagram production examples3/24/2024 ![]() Their work was used in Japan in 1950–1955, which, combined with Japanese culture and lifestyle, led to the concept of Total Quality Management (TQM). Groundbreaking changes in the attitude to the quality of products and services took place thanks to the American scientists William Deming and Joseph Juran. Quality and the concepts related to it have evolved from antiquity to the present. The EN ISO 9001:2015 standard says that quality is the extent to which a set of inherent properties meet requirements. ![]() Tse Li used to say that quality is “excellence, perfection of workmanship”. Ĭrosby defined quality as the fulfillment of requirements and Juran defined it as usability or applicability. The identification process can be supported by other techniques, for instance, a kinship diagram or teamwork (like brainstorming), which trigger creativity and some freedom in defining problems and organize corrective or improvement actions. An example is the Ishikawa diagram and the 5 Whys method, which make it possible to identify the causes, places, and problems with insufficient quality, not only of products but also of defects in the broader sense. ĭespite the constant changes in the reasons for production decisions, the tools and methods of quality management known for a long time remain constant and effective. In still other situations, quality may be defined as specific operating conditions, functional features, and features of the work environment, in relation to the natural environment, esthetic values, and others. In one case, it will be identified with the characteristics of the product, in another-with a specific manufacturer. įor these reasons, quality can be perceived in different ways. In addition to the abovementioned concepts, decisions are also influenced by social and cultural conditions, customs, financial resources, and many other factors. All these elements are somehow “fastened together” by the clamp of the management philosophy. The classic production model draws attention to the input elements, such as materials, energy, and knowledge, and to the output elements-products, services, and profit, which are processed in a specific way conditioned by technology. ![]() ![]() In addition, the manufacturing process is significantly affected by the environment in which legal and normative guidelines change various concepts of production management appear, such as Total Productive Maintenance regarding the maintenance of the machine park in efficiency, Cleaner Production expressing the need to reduce the negative impact of production on the natural environment, and implementation of a systemic approach based on ISO 9001 (quality management), 14001 (environmental management) or 45001 (occupational safety management) standards. An example of a particular challenge may be the concept of Industry 4.0, which talks about mass-scale production of individualized, unitary products. The range of produced products can be very different at different times of the year. In production, the method of carrying out the production process may change modern technologies and different devices and materials are implemented. In production plants, with a constantly changing range of manufactured products, the challenge is to maintain a certain acceptable level of production, especially in relation to product quality. Production management is currently a difficult but also interesting and dynamically developing field. ![]()
