The study examines an efficiency problem in a Zinc Metallurgical Plant in terms of compliance. Unplanned Maintenance information, spare parts scarcity, and pipe corrosion from the year 2022 were used as the database. During the analysis of the root causes, it is discovered that the problem originates from limited availability and low performance, resulting in an Operational Efficiency Index (OEE) of 55%. Therefore, Total Productive Maintenance (TPM) was chosen as the primary approach to design the solution. This approach involves various actions based on TPM's pillars and is divided into three phases: planning, implementation, and stabilization over time. The use of Failure Mode and Effects Analysis (FMEA) and 5W+2H is incorporated as catalyzing elements to improve maintenance plans. These plans will determine maintenance tasks and execution frequencies, which will be managed through TPM's pillars, including planned maintenance, autonomous maintenance, and focused improvements. As a result, specific solutions were developed to address various issues. Finally, the entire proposal was implemented over the course of 2023 through a 24-week pilot project, resulting in the following improvements: an increase in availability from 83% to 96%, an increase in performance from 70% to 89%, maintaining quality at 95% as set by the company, and consequently, an increase in OEE from 55% to 81%. This increase led to an Internal Rate of Return (IRR) exceeding 11%, confirming the project's viability.
