Data Vault 2.0 - why do we need business vault when we have information marts?

What's the purpose of having a business vault when we can apply business rules while building information marts?

Imagine several departments which share some business rules.

Either it would be possible to implement those common business rules for each and every Information Mart.

Or, using the Business Vault layer, there would be a central point for business rules and their implementation. All Information Marts can get data directly out of the Business Vault and put it into their structure. If the business rule changes, there is only one point which has to be changed.

If one department needs another business rule, a second one can be created directly in the Business Vault and would be available for other purposes as well.

Also the metadata documentation would only be a bit slimmer since not every Information Mart would show their own implementation of business rules.

So it is an architectural decision to put the rules as far downstream as possible for other following components.
