Is your WBS a scheduled based (activities, verbs) structure or deliverable based (nouns) structure? The PMI advises that it should be deliverable based. Please explain the reason for your choice.
To me, a deliverable based WBS is heading in the direction of Prince 2's Product Breakdown Structure (PBS). What would you say differentiates the two though? I liked this saying I found at the below link; 'If you like a WBS is an organised To Do List while a PBS is an organised Shopping List.'

Someone clearly in favour of a deliverable based (nouns) structure:
