Plant maintenance involves methods and practices to keep industrial facilities running efficiently, including regular equipment checks, cleaning, and safety measures. Poor maintenance can negatively impact productivity. The maintenance process involves documenting equipment conditions, planning and executing maintenance tasks, and recording maintenance history. There are different types of maintenance approaches ranging from breakdown/corrective maintenance to preventive maintenance and proactive strategies like total productive maintenance (TPM), which aims to eliminate waste and involve employees to improve equipment reliability and productivity. TPM's five pillars are focused equipment management, autonomous maintenance, planned maintenance, quality maintenance, and safety and health. TPM differs from total quality management (TQM) in its emphasis on equipment and processes rather than only products and services.
