Bottleneck According to Jonah
A manufacturing firmshould distinguishbetween bottleneck andnon-bottleneck resources
Bottleneck are resourceswhose capacities areequal to or less than the
demand placed upon it
The bottleneck resourcesdetermine the flow of
product through the plant

Is Bottleneck Good for a manufacturingplant?
An hour lost on the bottleneck is an hour lost
for the entire plant
An hour lost on a non-bottleneck is a
mirage
Manage the plant by the bottlenecks

Jonah: Bottleneck has no slack capacity
Solution:Alex organized the bottlenecks to work only on overdue
orders from the most overdue to the least
In order to keep the bottlenecks constantly busy, the teamformed a new system to inform the workers what materials
have priority at non bottlenecks.
Answer: Red and Green Tags
Twelve Orders got shipped
Problem No.
Does Bottleneck has a slack capacity?

Increasing the Production Capacity and Efficiency of the plant
Solution:
The production Manager fixed some of the old machines tocomplement what one of the bottlenecks did, thus increasing
the capacity
More Workers: One foreman for each location all the time.
Increasing the Efficiency: Mixing and Matching orders bypriority to process more parts, increasing efficiency by 10%.

What actually had happened was a result of some old thinking.Working non-bottlenecks to maximum capacity on bottleneckparts had caused the problem. All parts were stacked up in frontof the bottlenecks and others were awaiting non-bottleneck parts
for final assembly.

Solution
Schedule for the bottleneck parts can bemade in order to decide when they should bereleased, leading to alleviation of any excessinventory
For non-bottlenecks: Out of the data for thebottleneck parts to the final assembly, non-
bottleneck parts can be predicted.
