Best Practice:To determine if a specific data point (like "distance driven" or "odometer reading") exists in the system's schema, the BA should consult theData Dictionary. This auto-generated documentation lists all entities (such as Vehicle or VehicleIncident) and their associated fields (columns), along with data types and descriptions. This confirms existence even if the field is not currently exposed on the user interface.

Why Option B is better than A:Checking the UI (Option A) is unreliable because a field may exist in the database but be hidden, disabled, or not placed on the specific screen the BA is viewing.

Why Option B is better than C:The Application Guide (Option C) describes standard features and workflows but does not provide a granular, technical list of every database column, nor does it reflect any custom schema extensions added by the implementation team.

Why Option B is better than D:While Guidewire Studio (Option D) is a powerful tool thatcanverify this, it is primarily a developer environment. For a Business Analyst, the Data Dictionary is the intended, accessible "Source of Truth" artifact for data modeling questions without requiring IDE access or technical code navigation.
