CAPM Business Analysis Frameworks Practice Question
A business analyst is tasked with modeling the logical data requirements for a new customer relationship management (CRM) system. Which artifact should the BA create to show the relationships between customer entities and their attributes?
⚠ Common exam trap
Candidates often confuse a data modeling artifact (ERD) with process or interaction models (context diagram, use case diagram) or agile planning tools (user story map), leading candidates to pick a diagram that shows 'what the system does' rather than 'how data is structured'.

Correct answer & explanation
✓
An entity-relationship diagram
The entity-relationship diagram (ERD) is the correct artifact because it specifically models logical data requirements by showing entities (e.g., Customer, Order) and their attributes (e.g., CustomerID, Name) along with the relationships between them (e.g., one-to-many). This directly addresses the task of modeling data for a CRM system, where understanding how customer data relates to other entities is critical.
