Question 1

constraint

Answer 1

any factor that limits the performance of a system and restricts its output

Question 2

bottleneck

Answer 2

a constraint that limits the orgs ability to meet the product volume, product mix, or demand fluctuations required by the marketplace

Question 3

theory of constraints

Answer 3

the key point is if you want to improve the speed of your process you should focus on balancing your flow

Question 4

anytime you want to make process improvements

Answer 4

look at balancing your flow

Question 5

key principles of TOC (pg 180)

Answer 5

1. balancing flow, not on balancing capacity
2. inventory is needed only in front of bottlenecks
   inventory is usually the biggest overhead

Question 6

key principles:bottlenecks

Answer 6

work should be released into the system only when needed by the bottlenecks
bottle flows=market demand

Question 7

key principles:activating a non-bottleneck resource

Answer 7

is not the same as utilizing a bottleneck resource

don’t start doing stuff until you need to

Question 8

How to do the TOC pg 180

Answer 8

1. identify the system bottlenecks where there is less capacity than all other processes, out had the highest total time per unit processed, look for or has the highest average utilization or total workload
2. exploit the bottlenecks
3. to support the bottleneck schedule-so don’t produce more than you bottleneck can handle
4. elevate the bottlenecks (strongly consider trying to increase capacity of the bottleneck-add another worker or equipment)
5. do not let inertia set in
