The old era of maintenance was "fix it when it breaks down". However, with time people started to understand that preventive maintenance is needed to avoid loosing productive time. Tasks such as greasing, changing filters and consumables will be carried out to extend the productivity and overall lifecycle. Maintenance should be managed which starts with complying with the Original Equipment Manufacturer (OEM) maintenance guide. Nevertheless, it is also important to understand that some of those guides are designed to avoid failures within the warranty period, therefor, on a regular basis maintenance should be treated from an organizational learning to achieve optimum equipment productivity with the most efficient cost.
My work environment is maintenance engineering with preventive, predictive and corrective tasks scheduled. However, it would be interesting to carry out an investigation on what tasks are done more than needed leading to in-efficient cost by using engineering mechanics analysis calculation to understand the concerned component capability and need for maintenance. Also, to analyzed the most recurring failures and suggest a possible preventive task on avoid downtime.
