Using the definitions from the text, describe and illustrate the similarities and differences
between a constraint and a bottleneck.
From our text:
A constraint is any factor that limits the performance of a system and restricts its output
[ CITATION Kra22 \l 1033 ]. Constraint management is to find the right balance of
forecasting, developing, and implementing the work and resources. To be out of balance
results in the creation of constraints.
A bottleneck is a type of constraint. It is defined as
any resource whose available
capacity limits the organization’s ability to meet the service or product volume, product
mix, or fluctuating requirements demanded by the marketplace
[ CITATION Kra22 \l
1033 ].
The similarity between these two is that each definition tells us how it restricts the process.
However, a constraint can be called a bottleneck, but a bottleneck is not always a constraint
[ CITATION Hoh14 \l 1033 ]. A bottleneck is not always a constraint because some processes may
have more than one place where a bottleneck occurs. However, the constraint comes from what
is ultimately limiting the end product.
Chris Hohmann shows us this diagram and tells us the goal for the factory is to produce 100
units per day. A-F are each their own resource toward the unit. We can see a bottleneck at B in
the subassembly and a bottleneck at E in the overall factory. Although there is a bottleneck at B
in the subassembly, the constraint is E as E is the factor limiting the overall production of 100
units per day [ CITATION Hoh14 \l 1033 ].
