Work breakdown structure is a hierarchical decomposition of the scope/work that needs to be estimated and executed during the course of the project in order to accomplish the project objectives and deliverables. Here in this diagram scope document is breakdown into high level requisition 1, 2 & 3 and defined deliverables 1, 2 & 3. Again, the high-level requisition 1 and defined deliverables 1 is branched into system change 1, 2 & 3. Like this way high-level requisition 2 & 3 and defined deliverable 2 & 3 are branched into system change 1, 2 & 3. This system changes 1, 2 & 3 are sub divided into two or three sub branches and so on. EdrawMax allows its users create their own work breakdown process & make them understand in better way.
