The aim of the master's thesis is to determine the impact of quality costs on manufacturing efficiency based on the literature analysis on quality costs and manufacturing efficiency and empirical quantitative analytical research. Tasks set to achieve the goal of the master's thesis: 1. Based on the literature analysis, determine methods and models of quality cost evaluation and select a suitable model for further research; 2. Based on literature analysis, detail the concept of manufacturing efficiency, revealing the constituent elements of manufacturing efficiency; 3. Based on the examined literature, prepare a research conceptual model and methodology; 4. After completing a quantitative study, explain the impact of quality improvement activities (quality costs) on manufacturing efficiency and its individual elements. The methods used to achieve the goal in this work: the structure of quality costs, evaluation methods, classifications and designations of activities were explained during the analysis of scientific literature. The topic of manufacturing efficiency is also reviewed, what elements it consists of and how it is evaluated. This made it possible to understand the possible relationship between the concepts and to prepare the research model. Analytical quantitative research was chosen as the method of empirical research. A questionnaire survey was chosen as an instrument to implement the research. The questionnaire was prepared based on literature analysis and interviews with experts. Production representatives, such as manufacturing units managers, department heads, production foremen or planners, were selected as respondents, as they are people who deal with quality requirements and activities, as well as having knowledge about changes and evaluations of production aspects. The received answers were analyzed with SPSS IBM Statistics, JASP and Excel programs. The study found that the relationships between quality improvement activities and manufacturing efficiency and its elements vary greatly. Out of 10 tested hypotheses, 4 statements were confirmed: prevention quality improvement activities had a positive influence on manufacturing efficiency, prevention quality improvement activities had a positive influence on material efficiency, appraisal quality improvement activities had a positive effect on human resource efficiency, equipment efficiency had a positive influence from appraisal quality improvement activities. |
