Abstract:
The article presents an implementation attempt of the DMAIC method used in the Six Sigma concept for the improvement of production processes connected with maintenance. Thanks to the tools included therein (process map, FMEA, SIPOC chart) we were able to define the: problem, i.e. which types of breakdowns cause the most machine stoppage; precise structure of the failure removal process and its needs, owners, resources, client-supplier relationships in particular sub-processes; source causes for overly long stoppages.
Learning the process and the causes of malfunctions allowed us to develop improvement procedures aimed at minimising the fault removal times. The procedures developed have been implemented in the company alongside a control plan, which will ensure supervision and their efficient functioning in the future.
