Analyzing Complex Decisions

Suppose you have a decision with many tables and complex interrelationships like this:

They are all artificial rules for the purpose of example but how do we know if this is a good rule model?

• Are there any conflicting rules (not just within a table but across tables)
• Are there gaps in the conditions being tested?
• Are there missing rules (and what are they?)
• Are there any redundant rules (could we express the same logic with fewer rules?)

If you had to figure this out manually it could take a very long time. Fortunately the BizVR Auditor can do a lot of this for you.

And even after this we still need to confirm that the rules modeled are the correct one to solve the business problem - that's where testing comes into play.
