A Comunicação entre os Setores de uma Empresa como Principal Ferramenta da Qualidade na Produção Enxuta
(Instituto de Tecnologia, 2020) BASTOS, Riomar Martins; MAGALHÃES, Edilson Marques
The need to improve service to end customers and suppliers at a multinational in the Industrial Pole of Manaus, due to the low performance of its main KPI (Key Performance Indicator) OTD (On Time Delivery), which fluctuated at 56%, motivated this work. The objective was to raise this index to 92%. The methodology applied was centered on the philosophy of lean production and quality tools, with a survey of the main problems that negatively impacted the main KPI. The results pointed to communication between sectors as the main problem, and with the support of the board and the application of continuous improvement, it was possible to raise the KPI OTD to 92%, currently achieving a delivery rate of 99%.

Aplicação do Método Schumacher como Alternativa para Calibração e Validação de Torquímetros no Processo de Montagem de Motocicletas
(Universidade Federal do Pará, 2018) BRANDÃO, Leonize Thomé de Souza; MAGALHÃES, Edilson Marques
This case study analyzes the calibration and validation process of torque wrenches in a motorcycle assembly plant. Torque wrenches are validated within a short period under strict parameters to ensure compliance, requiring time availability and, in some cases, new equipment. The objective is to optimize this process, making it more efficient and reducing costs without compromising product quality. As an improvement alternative, this study proposes the reformulation of calibration periodicity using the Schumacher Method and reassessment of the approval and rejection parameters. The study followed the implementation of these improvements over six months, demonstrating positive results in reducing process time and increasing the efficiency of torque inspections.
