To draw: A process flow diagram for this process.
a)
Explanation of Solution
Given information:
Process flow diagram:
b)
To determine: The capacity at the resource “Dentist”.
b)
Explanation of Solution
Given information:
Calculation of capacity:
Formula:
The capacity at “Dentist” is 20 patients.
c)
To determine: The bottleneck in the process.
