Checking for Correctness

You perform correctness checking to confirm that the analysis model accurately represents the business requirements. The project can then use this verified model in subsequent stages of system development.

In particular, you address these questions to ensure a full and accurate representation:

• Have attributes been grouped with the correct entity?
• Does the model exclude all unnecessary elements?
• Does the model look right to the end users?

Correctness checking includes these techniques:

• Process dependency checking
• Normalization
• Redundancy checking
• Quantity cross-checking
• Structured walkthroughs
