Where do we start?

Step 1: Address Your
Bottlenecks
Dana Pylayeva and Bryan C. BeechamThis work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported License
1. Identify the system's constraint(s).
2. Decide how to exploit the system's constraint(s).
3. Subordinate everything else to the above decision (align the whole system or organization to support the decision made above).
4. Elevate the system's constraint(s) (make other major changes needed to increase the constraint's capacity).
5. Rinse and Repeat:
Warning! If in the previous steps a constraint has been broken, go back to step 1, but do not allow inertia to cause a system's constraint.
Theory of constraints. Systems thinking.
