Abstract
This study examines the relationship between Total Productive Maintenance (TPM) Implementation and Overall Equipment Effectiveness (OEE) in manufacturing firms in Rivers state. This study was operationalized by Productive Maintenance (TPM) Implementation as the predictor variable with dimensions of autonomous maintenance, planned maintenance, quality maintenance and the criterion variable was Overall Equipment Effectiveness (OEE) with measures of availability, performance and quality.

The study revealed that there is a significant relationship between Autonomous Maintenance and Overall Equipment Effectiveness (OEE) in manufacturing firms in Rivers state. There is a significant relationship between Planned Maintenance and Overall Equipment Effectiveness (OEE) in manufacturing firms in Rivers state. There is a significant relationship between Quality Maintenance and Overall Equipment Effectiveness (OEE) in manufacturing firms in Rivers state. The study concluded that there is a positive relationship between Total Productive Maintenance (TPM) Implementation and Overall Equipment Effectiveness (OEE) in manufacturing firms in Rivers state.
