WBS is the breakdown of scope into products or deliverables that result from an activity or a group of activities. The WBS workpackages are broken down into activities to prpduce the workpackages.

A wise philosophy teacher taught me in college, there is nothing quite like the power of analogies to break down complicated concepts into simple terms that most everyone can relate to in any language. Think about it for a minute, I could go up to anyone on the planet and asked, in their native tongue, hey, what's the difference between a WBS and an Activity List? The answer would most likely be, I don't know. I am certain, by using the "Baking a fruit cake" analogy, you would see the "lights" come on! Assuming of course the person knows what a cake is and they have "lights" that work. Thanks Kiron for confirming my long held belief. Saving Changes...
