“So, what does it take to create a system like that?” I asked. “To create a system that would notify for rejected parts along with lead times for replacement parts and alternate suppliers?”

Valerie was shaking her head. “I know our computer software pretty well and to program that functionality would be pretty expensive.”

I reached in my bag and pulled out a handful of 3×5 index cards. “Suppose I said that you were not allowed to modify your software and the only tool you could use were these 3×5 cards? Now build a system. Let’s start with how frequently it happens.”

“You’re right,” Valerie started. “It doesn’t happen that often. Our QC guy who certifies incoming parts, could send a card with the details to our purchasing person. Our purchasing person has access to lead times and alternate vendors. Purchasing gets their order quantities from sales orders, so they could run a reverse report to find out what orders would be impacted, that’s easy.”

“What else do we need to know to effectively respond?”

“We would need to get our sales people involved to find out what wiggle room we have on those orders. Since we are three weeks ahead of the game, there are all kinds of adjustments that can be made with ample notification.”

“If I asked to draw a picture of this on a piece of paper using circles, arrows and labels, could you do that?”

“You mean, like a flow chart?” Valerie asked.

“Like a flow chart.”
