This project was developed within the company Alfa. This is a company in the field of tubes, hoses and access, which had its early in year of 2014 and show a great growth of area built, machinery and, consequently, an increase in production. There was determined work in all areas and sectors that make up the company for its growth. However, this establishment did not include the maintenance sector of the company. The definite consequences to be felt and this were translated into an increase in the number of failures, as well as an increase in the time taken to repair the machines. As a result, a specific structuring work for the maintenance sector was carried out. First, all machines were identified with a specific code that individualized them. Along with the codes, a cleaning and organization of the maintenance sector was carried out. At this time, all parts and approval items that were in the sector were also encouraged. The next step focused on systematizing and documenting maintenance techniques. The company already practiced planned corrective and unplanned corrective maintenance, but without any documentation. As preventive and preventive maintenance actions were not practiced. Alfa company is part of an international group. It is a guideline of this group to use EWOs (Emergency Procedure Orders) whenever there is a failure. These EWO sheets have been implemented and are used to document corrective maintenance actions. From these EWOs, data for the calculation of maintenance indicators are also taken. The indicators adopted were MTTR, MTBF and frequency of failures. As for preventive maintenance, this is also among the Alfa Group's guidelines. In fact, there was already a forecast schedule for each machine. This schedule started to be followed, and for its control the use of preventive maintenance sheets was adopted, with the objective of listing all the preventive measures carried out on each machine. For this reason, these sheets were attached to each machine. Sheets are constantly compared to the existing schedule. Finally, all purchases and service contracts started to be documented in a database, in order to have a more reliable value for the maintenance cost.
