CORE DEFINITION
Product Breakdown Structure, a hierarchical decomposition of project deliverables into manageable components, focusing on "what to deliver" rather than "what to do". Scaffolding role: decomposition with the end in mind. Starting from the final product and decomposing in reverse ensures that all work is directed towards deliverables, avoiding wasted effort.
SCAFFOLDING EFFECT
Reduce cognitive load
Decomposition with the end in mind. Starting from the final product and decomposing in reverse ensures that all work is directed towards deliverables, avoiding wasted effort.
Anchor fast decisions
Planning often starts from "what to do" (WBS activities), which can easily lead to focusing on means while forgetting "what to deliver". PBS starts with the end in mind, first decomposing the final product/deliverable into a component tree, ensuring that every activity points to a deliverable, thus avoiding wasted effort.
