WBS Dictionary is a document that provides detailed information about each component of the Work Breakdown Structure (WBS). It is used to define and describe the scope of work for each element in the WBS. The WBS Dictionary typically includes a description of the deliverable, its purpose, any assumptions made, any constraints or limitations, and any other relevant information.
The purpose of the WBS Dictionary is to provide a clear understanding of the scope of work for each element in the WBS. It helps to ensure that all stakeholders have a common understanding of what needs to be done and how it will be accomplished. The WBS Dictionary also serves as a reference document throughout the project life cycle, providing guidance on how tasks should be completed.
Using a WBS Dictionary can help to reduce misunderstandings between stakeholders and ensure that everyone has a clear understanding of the project scope. It can also help to identify potential risks early on in the project and provide guidance on how to address them. Additionally, it can help to ensure that all tasks are completed according to plan and within budget.
