今天，我们将讨论WBS Dictionary，这是一个重要的项目管理文件，可以补充工作故障结构。
This is an important document, and without it, you cannot monitor the scope performance.
WBS词典is a part of thescope baseline。The scope baseline has three components, and the other two components are the范围声明andWBS。
WBS词典
According to the PMBOK Guide, WBS Dictionary is “A document that provides detailed deliverable, activity, and scheduling information about each component in the work breakdown structure.”
WBS词典提供了有关WBS的每个元素的详细信息，包括可交付成果，milestones，，，，deliverables, scope, duration, starts and end dates, required resources, costs, quality, assigned team members, etc.
The Objective of the WBS Dictionary?
WBS词典is a good communication tool and helps利益相关者demystify the WBS and helps them understand WBS.
The second objective of the WBS Dictionary is to help avoidscope creep and gold platingby defining the scope of work. A clear work definition and transparent work assignment help avoid miscommunication, and team members will know what they are supposed to do.
No extra work will take place.
WBS字典补充了WBS，这是工作范围的图形表示。wbs是图形的，无法解释作品的范围，因此WBS词典进行了营救。它为WBS添加了其他信息，以使其完整并提高可用性。
WBS词典Template
The WBS must contain 100% of the scope of work, and you cannot show it using graphical or a tabular form. Therefore, WBS Dictionary explains the scope of work of each WBS element to ensure it covers all work.
Many experts call WBS Dictionary a work package description tool. They are also created hierarchically, like WBS, to explain the WBS element systematically.
如何创建WBS词典
You develop WBS Dictionary after creating theWork Breakdown Structure。You start creating it from the top-level element and move downward until you reach the工作包的水平。这种方法可以确保100%的工作范围all levels.
While creating a WBS Dictionary, use the template given in the above table to ensure that your WBS dictionary is short and meaningful and does not repeat the scope of work. You provide brief information with an easy understanding of the work package.
Use the following steps to develop a WBS Dictionary:
#1. Review the WBS
Review the WBS to ensure that team members understand it, and it covers 100% of the scope of work, and there is no duplication. If any modification is required in the WBS, make necessary amendments.
#2. Create Top-Level Elements
Determine what type of ID you will use to identify your WBS element. Afterward, name the top-level element, add an identifier and describe it. You can include primary delivery, budget, duration, milestone,assumptions and constraints，，，，andrisks。
＃3。创建低级元素
然后，您可以使用相同的模板创建较低级别的元素，并验证其覆盖工作范围的100％，并且等于父级。如果在上层需要进行任何修改，请进行更改。
＃4。创建工作包
工作包是WBS的最后级别。在这里，您可以分配负责人并将其确定为控制帐户。最后，验证100％的工作范围。

- 如果工作范围发生变化，请更新WBS字典。
