Operational Configurations Flashcards
1
Q
What is the relationship between capacity and operational configurations?
A
Capacity and operational configurations are nearly inseparable
Operational configurations add detail to capacity decisions
2
Q
What is the relationship between automation and configuration?
A
- Companies that need high volumes of relatively standard services or products configure their operations to be more automated
- Companies that need low volumes of unique services or products would configure their operations to be less automated, using more people with lots of locations that are relatively small
3
Q
Gantt Chart
A
Illustrates a project schedule
4
Q
StoF/Turnaround time
A
total work time
5
Q
Cycle time
A
rate at which a process completes a unit of work, determined by a bottleneck
6
Q
What is a bottleneck?
A
1) Rate limiting step of the process, can go no faster than the bottleneck
2) it is the resource with utilization at 100%, always working
3) sets maximum output, you can do no more work than the bottleneck
7
Q
Common Metrics of productivity
A
- Start to finish
- cycle time
- effective capacity
- design capacity
- utilization
8
Q
5 misunderstandings
A
- variance makes everything worse
- confusing start to finish with cycle time
- confusing design capacity with effective capacity
- adding capacity to a non bottleneck will not increase the throughput of a system
- doubling capacity at the bottleneck will not double the capacity of a system
