Estudo e aplicação das ferramentas de gestão da qualidade no subsetor de corte e vinco: um estudo de caso

Abstract

The market is becoming increasingly demanding, and companies have to adapt and produce with even greater quality without sacrificing production time, given the numerous changes and requalifications the industry is undergoing. The production of defective products or those that do not meet the quality standards required by customers is a significant dilemma in any industrial sector. These discrepancies have an impact on the excellence and efficiency of an organization. Manufacturing non-conforming items results in dissatisfied customers, returns for repairs, or even total product returns, leaving consumers dissatisfied and causing financial losses as well as damage to the company's reputation. This also affects the ability to retain existing customers and expand into new areas. The focus of this work was to develop and demonstrate the entire methodology and study of the Plan, Do, Check and Act (PDCA) cycle applied in the production area of a printing company located in the city of João Pessoa, PB. The objective was to reduce the Key Performance Indicator (KPI) of losses generated by certain machines in the cutting and creasing subsector of the aforementioned industry. To support the entire project, other tools were used to complement the process, such as the Ishikawa cause-and-effect diagram, the 5 Whys (5W) analysis, and brainstorming. All of these tools aided in the development of an action plan, with the chosen and most suitable tool for the company's reality being the 5W2H quality tool.
