When you start to implement TOC in an operations company you will be
aware of the TOC focused five step process. Identify, Exploit,
Subordinate, Elevate, Repeat (do not let inertia become the constraint
of the system). 

This
and other things you read about TOC might lead you to expect to start
the process by identifying the constraint directly. In fact the best
starting point is usually to do a more tactical step: Control (limit)
the input of work. 

This will bring immediate benefits of
speed, lower work in process, and free up capacity. It will also make
it easier to identify if there is a bottleneck or a CCR. You will also
probably find that On Time Performance improves. We pioneered this
approach in 1990 at Carnaud Metalbox Closures Europe UK in Poole in Dorset (now Crown Cork) and it has now been taken up by the wider body of TOC experts.

The time gained will enable you to do a much better job of the implementation.

How
much to control the input by depends on the ratio between the process
time required to make a unit of production and the overall current
Throughput Time (time between release and dispatch). Before jumping in
take into consideration 
the reliability of the process and product
the degree of volatility in demandIf
you are in a project environment there is a similar starting action
that will bring big benefits and enable you to proceed with a full
implementation of critical chain more easily. Choking the release of
projects will help to reduce bad multitasking and gain speed the
completion of projects, reduce rework and increase the productivity of
key resources.
