Nowadays, to survive in the highly competitive industries, organizations require adapting to the rapid changes in the industrial environment to deliver the products or services with high quality in accordance with the consumer’s expectation. In order to achieve maximum efficiency, organizations endeavour to enhance their asset integrity, reliability, availability, productivity, maintenance practice, and concentration on safety and product quality. It is also vital to ensure the highest maintenance efficiency practice in organizations to achieve the best efficiency practice. Therefore, this paper aims to identify the most influential factors that impact workforce productivity's Wrench Time (WT). Understanding the impacts of these factors on the WT and identifying their causes will provide a clear vision of how the management can allocate the necessary resources to eliminate these impacts. As a methodology, random sampling is used to determine the sample of observations from a given population. This sample is then used in the pilot test that is conducted to test the reliability of the data collection method. The Day In Life Of (DILO) approach is used to collect data as an observation method that involves the supervisor’s participation with the technicians throughout the whole working day. A case study based on one of the largest LNG plants in the Middle East is conducted to verify the achieved maintenance efficiency. As a result, workforce productivity has increased to 38.1%
