The paper presents a case study of the practical use of BOST surveys to identify problems that are the most important in production process. The research object is company from electrical industry. It was made the identification and of areas geneating problems from the second Toyota’s management principle point of view. Analysis of the research results was presented in the form of tables, histograms, radar chart and some statistical tools. Some production workers of the company with the help of BOST questionnaire survey showed, which factors are the most important. The aim of the analysis is to present which factors are the most important by building the significance sequences of obtained results. The results obtained for the type of small and medium-sized enterprises overlap with the results of tests verified in other enterprises.

An Identification of Areas Requiring Improvement in the Company Producing the Illumination – Case Study

Quality Production Improvement - QPI

2019

The article presents a case study of the practical use of BOST surveys to identify the most important areas that require improvement actions. It was made the identification and of areas requiring improvement from the fourteenth Toyota’s management principle point of view. According to this principle it is crucial to determine the causes of problem by solving technical issues. The research object is company from illumination branch. Some production workers of the company with the help of BOST questionnaire survey showed, which factors can bring the best effect after being improved. In frames of the work it was made characteristics of the research object - producer of illumination, the presentation of research methodology and content fourteenth Toyota’s management principle. Based on the survey results of carried out on the population of production workers, a series of importance areas for improvement was formulated. The aim of the analysis is to present which factors are the most important by building the significance sequences of obtained results. In the article were presented results of analysis with using circular charts, box-and-whisker plots and some statistical tools. The results obtained for the type of small and medium-sized enterprises overlap with the results of tests verified in other enterprises.
