Abstract

The article addresses the implementation of a productivity project aimed at improving the monitoring of production lines, providing a clearer view of mechanical equipment failures and their impact on maintenance performance indicators. With the implementation of the project, it was possible to generate a failure history, which helped guide and support preventive maintenance efforts. Analyzing the failures in production line machinery allowed for better judgment, preventing the allocation of resources to inappropriate procedures. For the execution of the project, the following tools were used: Logbook, Pareto Diagram, and 5W1H. First, the Logbook and 5W1H were incorporated into the machine operators' work routines through a form, to identify the causes and effects of the failures. The Pareto Diagram was used to handle the information, highlighting the main impacts and prioritizing the most significant factors in operational interruptions, requiring immediate attention. It also helped generate action plans to minimize them, using the 5W1H methodology. As a result, there was an improvement in production time utilization (PTU) indicators, machine efficiency, line efficiency, and packaging loss reduction. Additionally, an investment in new equipment for the production line was recommended. However, the project does not guarantee that the indicators will always meet the defined targets, but it does generate critical historical data for faster decision-making and more effective planning.
