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.
