Well… in our case, explaining "process" (or anything, for that matter) to our 5-year-old usually involves relating everything to either dessert, trains, playtime, being sad, or time-outs. Often in that order. Jargon with terms like, "inappropriate", "generous", "keep your hands to yourself" and "chill out" don’t register. He’s just not relating to those words.
Sometimes it seems that executives have similar limitations.
I’ve come up with a list of (hopefully) jargon-free business benefits to CMMI. These are boiled-down to their barest shadow of the full explanation. Though, sometimes, to get what you want, that’s all that’s needed.
I hope you find them helpful.
