Problem
A Work Breakdown Structure (WBS) is a hierarchical structure of things that the project will make or outcomes that it will deliver"
WBS doesn't describe any actions. Instead, every item is a noun describing an end product - a bicycle seat, fork, handlebar, etc.
This is one of the fundamental features of a WBS: it describes deliverables, not the activities necessary to get there. If there are any verbs in your WBS, then you're doing something wrong. For example, if you're creating a work breakdown structure for manufacturing a car, you'll include items such as "car body" (a deliverable), not "welding steel" (an activity).
Consider that you are asked to produce a WBS for a project you have had experience with in the past. Create then post a WBS Chart or compose as an outline in your initial post, be sure to adequately explain too!
