9.1. Sam's New Requirement
Sam met me for lunch at the local vegetarian bistro.
"You know, I was thinking," Sam began.
"Thinking up more things to do, I presume?" I replied.
"Well, yeah. I'd like to keep a report of what each customer is currently renting. Sometimes we get calls from customers who can't remember if they have any CDDiscs currently rented. They are a little absent minded," he stated.
"OK, it should just be an MM change," I said.
"An MM change?" he queried.
"Yes; a Major Minor change. It's a major change, since it involves keeping more information than we currently do. However, it's minor since we only need to rethink how our classes are arranged," I answered.
"That's good. So the other thing I was thinking about is probably an MM too," he said.
"What's that?" I asked.
"I'd like to keep track of all the CDDiscs that a customer has rented. I will be offering discounts to frequent renters in the future," he replied.
"Well, that's not quite as MMish," I said. "Tim and I will discuss it and get back to you."
