The activity-based approach In Work Breakdown Structure (WBS) we: • Identify the main (high level) tasks (activities) required to complete a project. • Then break each of these down into a set of lower-level tasks.
The activity-based approach In Product Breakdown Structure (PBS)we: • Show how a system can be broken down into different products for development.
The activity-based approach In Product Flow Diagram (PFD)we: • Identify the order of precedence of products and will typically include multiple and complex parallel paths.
Case Study • Table Production Example . • Apply WBS • Apply PBS • Apply PFD
PBS Table product Module product System product Management product Progress report Table constructed document Table design Material specification Part Prepared File Part assembled catalog Overall System specification Integration test cases Test integrated software
PFD User requirements Overall System specification Table design Integration test cases Material specification Part prepared file Part assembled catalog Test integrated software
