This is strongly evidenced by the limited use of indicators for maintenance management and of tools, methodologies or techniques to support failure analysis. While companies
affirm that activities aimed at reducing the downtime are performed, the percentage of
time devoted to preventive activities is very low, according to the collected data.
Aspects as limited budget, low number of technicians, parts shortages and training were considered by companies as factors that strongly contribute to a maintenance performance under expectation. Even with respect to the planning of preventive activities, the majority performs annual and monthly planning,evaluation/revision is relatively insufficient since for a high number of companies, it is made only using the directions offered by manufacturer's manual. Activities plan based on the machine's manual makes the maintenance plan outdated and barely able to act on faults with the passage of time.
