A method for supporting operating and/or changeover processes for a machine, in particular product type changeovers in the beverage processing industry, for a machine, the method comprising the following steps: creating a description of the operating and/or changeover process which can comprise a plurality of sub-steps; processing the operating and/or changeover process and/or individual sub-steps; storing the operating and/or changeover process and/or the processed sub-steps; wherein processing comprises: generating workflows that comprise a number of sub-steps for users; distributing the operating and/or changeover process and/or individual workflows and/or individual sub-steps to end devices ; defining the location of the operating and/or changeover process and/or the sub-step with the help of coding provided on the machine to be changed over; wherein the sub-steps are different on different end devices (401, 401', 401"); wherein the operating and/or changeover process of the machine is explained to an operator by the sub-steps, such that the operator is enabled to perform the changeover process or one or several sub-steps of the operating and/or changeover process; wherein the operating and/or changeover processes comprise at least retrofitting of a blow molding machine, comprising a changeover of blow molds of the blow molding machine from a first size to a second size. creating a description of the operating and/or changeover process which can comprise a plurality of sub-steps; processing the operating and/or changeover process and/or individual sub-steps; storing the operating and/or changeover process and/or the processed sub-steps; wherein processing comprises: generating workflows that comprise a number of sub-steps for users; distributing the operating and/or changeover process and/or individual workflows and/or individual sub-steps to end devices ; defining the location of the operating and/or changeover process and/or the sub-step with the help of coding provided on the machine to be changed over; wherein the sub-steps are different on different end devices (401, 401', 401"); wherein the operating and/or changeover process of the machine is explained to an operator by the sub-steps, such that the operator is enabled to perform the changeover process or one or several sub-steps of the operating and/or changeover process; wherein the operating and/or changeover processes comprise at least retrofitting of a blow molding machine, comprising a changeover of blow molds of the blow molding machine from a first size to a second size. generating workflows that comprise a number of sub-steps for users; distributing the operating and/or changeover process and/or individual workflows and/or individual sub-steps to end devices ; defining the location of the operating and/or changeover process and/or the sub-step with the help of coding provided on the machine to be changed over; wherein the sub-steps are different on different end devices (401, 401', 401"); wherein the operating and/or changeover process of the machine is explained to an operator by the sub-steps, such that the operator is enabled to perform the changeover process or one or several sub-steps of the operating and/or changeover process; wherein the operating and/or changeover processes comprise at least retrofitting of a blow molding machine, comprising a changeover of blow molds of the blow molding machine from a first size to a second size. <EOS>
