What are the key differences between Work Breakdown Structure (WBS) and Network in SAP Project System (PS)?

Key Differences Between Work Breakdown Structure (WBS) and Network in SAP Project System (PS)

1. Definition: WBS represents the hierarchical structure of project tasks, while Network shows the sequence and interdependencies of activities.
2. Hierarchical Structure: WBS is a top-down approach where tasks are divided into smaller subtasks, whereas Network is a bottom-up approach defining the flow of activities.
3. Focus: WBS focuses on organizing and categorizing project work elements, while Network focuses on scheduling and sequencing tasks.
4. Dependencies: WBS does not show task dependencies explicitly, while Network displays the relationships between activities through predecessor and successor links.
5. Visualization: WBS is represented as a tree structure, while Network is depicted using graphical diagrams like PERT or Gantt charts.
6. Usage: WBS is used for cost and resource planning, while Network is utilized for scheduling, resource allocation, and critical path analysis.
