Maintenance service is the necessary organizational structure in the modern manufacturing company. Everyday maintenance services operation would be greatly impeded without a computerised maintenance management systems (CMMS) software. CMMS allows to manage company’s equipment, planning inspections and maintenance and management supervision procedures and service documentation. The aim of this study is to present the analysis of the manufacturing company in the maintenance department, the main objectives of the company related to the maintenance, a pre-implementation analysis (objectives, assumptions, hard results, ABC analysis), and proposals to choose computerised maintenance management systems, which will allow to reduce failures, downtime and maintenance costs.
