Summary

• We have illustrated the impact of depleted
  resource availability. We have observed
• Patient queue times increasing
• Number of patients on the premises increasing
• Treatments delayed because of increased blocking
• Too little resource can cause the system to
  break.
• To what extent is resource availability reduced
  during the working day?
• How can we reduce the level of resource depletion
  in our working day?

Interlude insight

• An ideal system delivers patient value by getting
  the right resources in the right place at the
  right time in the right quantity...
• with no waste.
