Components of WBS

In most textbooks and publications, WBS basically appears in the form of an organizational structure diagram, which clearly shows the structural characteristics of WBS. However, unfortunately, it cannot show all the meanings of WBS. How is the full connotation of WBS reflected?

First, let's look at the definition of PMI: work breakdown structure. They are three key elements: work-a task that can produce tangible results; decomposition-a hierarchical structure that is gradually subdivided and classified; structure-components are organized according to certain patterns (pratice standard for WBS, PMI ). Based on these concepts, WBS has corresponding components: blog.mypm.net

Structured Encoding

Encoding is the most significant and critical component of WBS. It is first used to thoroughly structure WBS. Through the coding system, we can easily identify the hierarchical relationships, grouping categories, and features of WBS elements. In addition, due to the development of modern computer technology, coding actually makes WBS information closely linked with organization structure information, cost data, progress data, contract information, product data, and report information.

A Work Package is the underlying element of WBS. A general work package is the smallest "deliverables ", these deliverables can easily identify the activities, costs, organizations, and resource information to complete it. For example, the MPs queue installation package may contain activities such as the preparation and installation of MPs queues, MPs queue connection and installation, and strict inspection; includes transportation/welding/pipeline production labor costs, pipeline/metal accessories and materials costs; Reports/inspection results generated during the process and other documents; and assigned teams and other responsibilities. These organization, cost, progress, and performance information make the work package and even WBS the foundation of project management. Based on the above point of view, a wbs for project management must be broken down to the Work Package level to make it an effective management tool. Project Management Alliance

The WBS elements are actually "nodes" in The WBS structure. The common understanding is the "Boxes" on the "organizational structure diagram ", these boxes represent independent "deliverables" with affiliation/Summary relationships ". After decades of summarization, most organizations tend to have a WBS structure that must be related to the project objectives and be oriented to final products or deliverables, therefore, the WBS element is more suitable for describing the nouns of output products (effictive WBS, Gregory T. haugan ). Obviously, different organizations and cultures use different methods, procedures, and resources to accomplish the same job, but their results must be the same and must meet the prescribed requirements. Only by grasping the core deliverables can we control and manage projects most effectively. On the other hand, only Deliverables can be identified to identify the methods, procedures, and resources used by internal/external organizations to complete the work. A Work Package is the underlying WBS element.

WBS dictionary
Transferred from project management Alliance
The standardization and standardization of management have always been the goals pursued by many companies. The WBS dictionary is such a tool. It is a document used to describe and define the work in the WBS element. The dictionary is equivalent to the specification of a WBS element, that is, the work that the WBS element must complete and the detailed description of the work; the description of the work result and the corresponding standard; element parent-child relationship and element result input and output relationship. At the same time, The WBS dictionary also has a huge role in clearly defining the scope of the project, which makes WBS easy to understand and be accepted by participants outside the organization (such as contractors. In the construction industry, the Engineering Quantity List specification is a typical WBS dictionary at the Work Package level.

The above components are the most basic components, and their definitions are structured and conceptual. The information that WBS must contain is wise, because it is related to the management requirements of the WBS organization.
