Abstract
In order for a project to be well executed, managed and controlled, a Work Breakdown Structure (WBS) needs to be created. A WBS defines and organizes the scope of a project in terms of deliverables and activities to create them. Each element defined by the WBS is utilized in project planning and implementation. However, as far as the author knows, no method has yet been presented for detecting omissions and oversights of the necessary tasks and components in WBS. Moreover, there are no valid criteria for determining whether the scale of a defined WBS element is appropriate from the perspective of administration and management. This paper proposes an effective method for applying Network logic to the creation process of WBS. Furthermore, by estimating critical path, we can specify those activities that have tight deadlines. This enables us to determine simultaneously parallel processing and allocate additional resources as necessary.
