This article aims to allow Minota Metalworks and Manufacturing share company in Sodo city. Ethiopia to achieve preventive Maintenance scheduling involves functional checks, repairing or replacing necessary devices, machinery, and supporting utilities in industrial and governmental installations. Maintenance is keeping something in good condition and the process of continuing something or keep it in existence. However, the company has faced high machine downtime caused by poor maintenance practice and leads the company to low productivity. Preventive maintenance is maintenance performed to avoid failures, safety violations, and unnecessary tasks to keep something such as a building, machine, or piece of equipment required and in production costs and losses. This article is conducted on Minota Metalworks and Manufacturing company to improve preventive maintenance (PM) scheduling and develop accidental budget planning for the maintenance department to enhance productivity. To address such a problem, this article mainly includes calculation and explanation. It also presents the company's existing problem and finally provides a solution by preparing an improved maintenance schedule to enhance the company loss due to poor preventive schedule practice.
