Interesting Developments • Worst LT problem was super easy to fix. • During kanbanand 5S work, team discovered $25,000K of expired material and $17,000 of obsolete material. • Forged a far stronger relationship between hospital and radiologists. • Collecting copays in Imaging was reversed. • Implementing voice recognition took 2 years due to technology issues. • Creating a break room for techs boosted morale beyond anyone’s expectation.

- 42. Miscellaneous Tips • Team composition – Leaders; You may have to pay subcontractors •Choosing when to go to the Gemba and when not to. • Involving staff before and during mapping. • Pre‐mapping Data Collection – how much is too much; how much is too little. • FS VSM is a living document; visually post!
