A business process efficiency consultant concluded his presentation with a note of caution..."Don't try these techniques at home."

"Why not?" asked somebody from the audience.

"I watched my wife's routine at breakfast for years," the consultant explained. "She made lots of trips between the fridge, stove, table and cabinets, often carrying a single item at a time. One day I told her, "You're wasting too much time. Why don't you try carrying several things at once?"

"Did it save time?" the person in the audience asked.

"Sort of" replied the consultant. "It used to take her 20 minutes to make breakfast, now I do it in ten."
