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?
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.
- Ignore-Pretend the problem doesn't exist.
- 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.
- Dominate-Keep the problem to ourselves, don't include anyone in resolving it.
- Stagnate-Nothing changes, constraint continues.
- Fail-Unsolved problems breeds failure.
