In my final assignement we looked into raising productivity or minimizing wastes in the production using lean methods and minimal financial investements. To achieve that in the chosen company, where lean methods are being introduced into production, we identified the problem using OEE, which was 48 %. We indentified the problem as material change on a die press, which could be solved by introducing SMED method and restoring 5S method. With the help of spaghetti diagram, video of change of material, and analysis with the work team, we came up with propositions for improvements, that were executed based on price criteria and return of investement. Time of material change was shortened from 12:14 minutes to 7:59 minutes, which represents 65,3% of the original time. With this time savings we saved 14.631,9 € in cost price of the product in 1 year span. We also raised OEE to 56 % and expect fort the investement to be returned in 0,007 years time.
