 Constraint
The constraint to a system is the bottleneck that limits the system from accomplishing more and more
of the system goal.
The goal of for-profit businesses is to make money, now and in the future. The goal of not-for-profit
organizations (business,
volunteer, religious, government) is to attain more and more of goal they are organized to achieve.
For example, the goal of
a health care organization is more and more healthy people at higher health levels. Increasing flow
through a constraint
increases goal achievement of the system. Increasing flow through a constraint frequently leads to something
else
becoming the constraint. A constraint can be physical (e.g. a machine throughput), it can be a policy
(written or unwritten),
it can be a mental limitation (e.g. mind set, paradigm), it can be a process or procedure, it can be
a measurement, or it
can be any resource the system requires to operate to achieve its goal.
