How do the 7 wastes affect revenue cycle metrics?

The seven wastes directly impact key performance indicators.

  • Transportation waste increases days in AR through unnecessary routing
  • Inventory waste (backlogs) directly impacts cash flow and aging metrics
  • Defects create rework loops that multiply labor cost per claim

These technical impacts compound: high denial rates create backlog, which creates rework.
