When I was the Chief Government test piolt at the Sikorsky factory in the mid 90's we took on a few Kaisan projects.
The result were very compelling and we were able to really streamline the production acceptance flight test procedures.
On an administrative Kaisan, we tracked every DD-250 (the form the government uses to accept product from a vendor) in the factory. We found that there were over five
dead people on the DD-250 distribution list still getting copies
Every enterprise needs a periodic spring cleaning...tailor the tools available.
