APPLICATION OF QUALITY TOOLS - STATISTICAL PROCESS CONTROL AND ISHIKAWA DIAGRAM IN DETERMINING THE QUALITY OF A LEMON PRODUCTION PROCESS

Abstract

With the increasing competitiveness in the market, companies seek to improve their global performance and obtain an ideal quality standard, in order to obtain an excellent competitive advantage. In this context, the objective of this work is to apply Statistical Process Control (CEP ) in lemon production culture using quality control methods and tools and then, the application of the Ishikawa Diagram, 6M method. The research was carried out through a case study of the lemon production process of a company located in the interior of São Paulo. After applying the Statistical Process Control, where it was justified that the said process was statistically controlled. Subsequently, the Ishikawa Diagram, 6M Method, was applied, which allowed identifying the existing inconsistencies. In this sense, the two quality tools are used to investigate inconsistencies in the process of varying lemon thickness and propose measures to improve the company's production process.
