Tiffany's organization of necessary instruments outside the interventional suite prior to procedures employs which lean tool?

The correct choice is indicated as SMED, which stands for Single-Minute Exchange of Die. This lean tool is designed to reduce the time required for equipment changeovers or setup processes, focusing on efficiency and streamlining operations. In Tiffany's case, organizing necessary instruments outside the interventional suite before procedures is a direct application of SMED principles. By having these instruments ready beforehand, the time needed to prepare for procedures is minimized, thus improving workflow and enhancing the overall efficiency of the healthcare process.

This approach reduces waste in the form of time and effort, allowing healthcare providers to focus more on delivering patient care rather than spending time searching for or assembling instruments at the last minute. The successful implementation of SMED can lead to faster turnaround times between procedures and ultimately contribute to better patient outcomes and satisfaction.
