Work tasks that produce tangible results

Breakdown decomposition is a scene-level structure that gradually lowers scores and categories.

Structure Structure organizes various parts according to a certain pattern

WBS decomposes Buqiang Project→Task→Work→Daily Activities

Tools & Techniques

output

Determine project scope: Clearly and accurately state the scope of the project

Assign project work: Assign personnel to each independent unit and define the corresponding responsibilities of these personnel

Estimated project costs: Estimate time, costs and resource requirements for each independent unit to improve the accuracy of time, cost and liability estimates.

Control project progress: lay a common foundation for planning, cost, schedule, quality, safety and cost control, determine the benchmark for project progress measurement and control, and determine work content and work order

Translate project value: Link project work to the project’s financial accounts

100% principle: 100% coverage of the project's deliverables, and each sub-task decomposed by the screen must also 100% cover its parent task Fan Tao

Elements are mutually exclusive: Each element in the WBS structure is independent of each other and does not intersect.

Focus on outputs: When enumerating WBS work packages, plan according to the expected outputs, not just plan action events

Work package granularity: deliverable, assignable, responsibility assigned to person

Broken down by physical structure of product

Functional decomposition of technology product completion projects

Break down by implementation process

Breakdown by geographical distribution of projects

Broken down by project goals

Break down by department

Break down by function

Put forward a demand: Get the initial demand document when the user puts forward a demand

Requirements Confirmation: All project participants meet to discuss requirements, confirm all major project work, and determine how the project work will be decomposed.

Decomposition project If there are on-site pole plates, they should be used as much as possible

Sitemap creation: Draw WBS exhibition structure diagram

Create a detailed WBS, assign responsible personnel into organizational units, and divide the project into detailed enough that estimates (cost and duration) can be made for the work package. Arrange schedule, make budget, assign responsible personnel or organizational units

WBS review to verify the accuracy of the above scores

WBS version confirmation Establish a numbering system

WBS Updates Continuous updates to the WBS as its planned activities progress
