The master's degree thesis deals with the analysis of the quality management system in a selected organisation. The theoretical part focuses on history and quality management, quality principles and its concept. It describes the quality management system, its implementation and documentation. General standards and standards for hot-dip galvanising are an essential part for an easier orientation in the issues. The practical part describes a company engaged in hot-dip galvanising, the company's goals and the process of hot-dip galvanising. The next part provides a detailed description of the technological process concerning hot-dip galvanising to illustrate practically the quality management system. In order to follow the production process, one contract was selected and was closely observed during every step of the whole process of hot-dip galvanising. The last part of the chapter includes data analysis of the quality management system as well as a description of the Pareto analysis, which represents the only instrument of quality management in the organisation. The conclusion provides some improvement suggestions which should be applied by the company to enhance the quality management system and at the same time to prevent possible complications.
