There are essentially two ways to create a Work Breakdown Structure – the top-down or the bottom-up approach. The top-down approach, in my opinion, generates a complete and more accurate WBS.

This is because the meaning of the surrounding words provide a context to aid understanding.Is reading top down processing?
