WBS work breakdown structure
1. Definition of WBS work breakdown structure
①Work:
Work tasks that produce tangible results;
②Breakdown decomposition:
It is a hierarchical structure that is gradually subdivided and classified;
③Structure structure:
Organize parts according to a certain pattern
④WBS decomposition steps:
Project → Task → Work → Daily Activities
2. The "Create WBS" process in PMBOK
① Belongs to the scope management knowledge field;
②Input:
①Project management plan (scope management plan);
②Project documents (project scope statement, requirements documents)
③Business environment factors;
④Organizational process assets;
③Tools and techniques:
①Expert judgment;
②Decomposition;
④Output:
①Scope basis;
②Project file updates (assumption logs, requirements files).
3. The role of WBS
① Determine the project scope:
Clearly and accurately state the scope of the project;
②Assign project work:
Assign personnel to each independent unit and define the corresponding responsibilities of these personnel;
③Estimated project cost:
For each independent unit, estimate time, cost and resource requirements to improve the accuracy of time, cost and resource estimation;
④Control project progress:
Lay a common foundation for planning, cost, schedule, quality, safety and expense control, determine the benchmark for project progress measurement and control, and determine work content and work sequence;
⑤Conversion project value:
Relate project work to the project's financial accounts.
4. WBS decomposition principle
①100% principle:
100% coverage of the project’s deliverables, and the subtasks at each level of decomposition must also 100% cover its parent task scope;
②Elements are mutually exclusive:
Each element in the WBS structure is independent of each other and does not cross;
③Revolving around output:
When enumerating WBS work packages, plan according to the expected outputs, not just plan action events;
④ Work package granularity, deliverable, assignable, and responsibilities assigned to people.
5. Decomposition method
①Decompose according to the physical structure of the product
②Decompose by function of product or project
③Decompose according to implementation process
④Broken down by geographical distribution of projects
⑤Decompose according to each goal of the project
⑥Broken down by department
⑦Decompose by function
6. Decomposition of IT project WBS specific steps
① Put forward a demand: Obtain the initial demand document when the user puts forward a demand;
② Requirements confirmation: All project participants meet to discuss requirements, confirm all major project work, and determine the way to decompose project work;
③ Decompose the project: If there are on-site templates, you should try to use them;
④Sitemap production: draw the hierarchical structure diagram of WBS;
⑤ Make a detailed WBS: subdivide the project into enough detail to estimate the work package (cost and duration), arrange the schedule, make a budget, and assign responsible personnel or organizational units;
⑥WBS review: Verify the accuracy of the above decomposition;
⑦WBS version confirmation: establish a numbering system;
⑧WBS update: As other planning activities proceed, the WBS is continuously updated or revised until all work is covered.
