I’ve seen groups combine process mapping with 5S when the work space is part of a larger, more involved process. Creating a high-level map can make it clear what items should be available first or closest to a door. A more detailed map showing decision points can illuminate how often a process goes down the “yes” path vs. “no” and that can provide information relating to process steps that rarely happen. If a certain step is performed less often, than supplies for that step can be stored further away. Process mapping is such helpful tool anyway it’s hard for me to recommend not creating one!
