The use of after-failure equipment repair strategies in the chewing gum factory in the period 1996-2003 implied their low efficiency and productivity; OEE during this period amounted to approximately 46%. The introduction of TPM contributed to the increase, in the years 2004-2015, of indicator of equipment effectiveness OEE on average by 28%. MTBF, which is a measure of the time between failures, has been extended to 142 minutes, i.e. failure in the factory occurs on average every 2-2.5 hours. MTTR indicator, specifying the time required to repair the damage that has already occurred was reduced throughout the plant to 67 minutes, which should be considered as a good result, given that the earlier removal of failures took on average 4 hours. OEE indicator of the most failure frequent line in the period 1996-2003, amounting to 38% then, after modernization, through the process of introducing TPM, of its most unreliable component (feeder of trays) increased the value to approximately 80%. Much lower failure frequency of technological equipment resulted in a significant increase in productivity of the factory without having to invest in new production lines.
