Continuous Improvement using TOC and Lean Manufacturing. 

This site has information and examples about the basic concepts of TOC and Lean Manufacturing.   


Ely Goldratt, author of the book "The Goal", and originator of the Theory of Constraints training often asks this question of his students, "What are you waiting for?"

You know how to identify waste and substandard performance. You've been trained on how to list the cause of constraints. You also know how to list cures and subordinate others to help.   But, most of all, you know how good it feels to implement improvement and elevate a constraint.    So...why do you wait? Cool

TOC provides the toolsets for problem solving:

  1. Problem solving using the 5 focusing steps - simple but effective methods that anyone can do and benefit from.  This is my favorite method because it is simple, quick and easy.  See the links on the left for examples of using this method.
  2. Evaporating Cloud Problem Solving - method to identify the core confict causing the problem(s).
  3. Thinking Processes - comprehensive problem solving

But what if we don't do anything about our constraints. Sure we can rationalize doing nothing.

This type of behavior is called constraint mis-management.

  1. Innocent Ignore-Pretend the problem doesn't exist.
  2. Sealed Rationalize-Use insulation layers (excuses such as: it's not our fault; Our problems are different; Yes, but bad things will happen; We can't it's against the policy; We won't get the support,etc,etc,etc) to justify inaction.
  3. Yell Dominate-Keep the problem to ourselves, don't include anyone in resolving it.
  4. Embarassed Stagnate-Nothing changes, constraint continues.
  5. Frown Fail-Unsolved problems breeds failure.

This site also has quite a few examples of 5S Events - see the links on the left for examples.  5S is an incredibly powerful but simple and effective tool from LEAN (T.P.S).
