Start Point for Improvement in multi-stage process

Theory of Constraints. 
You need to know which of your sub-processes is the short fat kid on the Boy Scout hike. 

Hey, as a former short fat kid, I resent that (I was no Herbie).  You can’t take outward appearances or make assumptions – you must take data to find Herbie.

Dear Colleagues,
It’s not a miracle. Just apply the Six Sigma knoweldge you have as a Black Belt and you will find the best approach.
Take a process that is relevant for your internal and external Customer. Yep, you always should know your Customers’ requirements.
Four Selection Critieria (data is always helpful!):
* Process Sponsor who is committed to process improvement
* Process with a significant amount of cost and ressources on it
* Process that will be relevant for your organisation in future
* Process where the external customer will feel the difference
Does this help?!
Best, NorbertMBB cert. (GE)

I almost regret starting this descent into geekdom.  You know when you start making witty references to The Goal, its probably time to start getting outdoors a little more.
