Anthony,

>KBizRules seems clearly setup to handle data validation type rules. But what about other business processes like doing a credit check, or importing a data file? Should these rules be in the business object or in the business rules object and why?>>

Business rules fall into two broad categories...1) Data validation rules, 2) Domain rules.

Data validation rules verify things like must-key fields, proper ranges of values, etc. have been entered. An example of a domain rule is "New invoices cannot be generated for clients over their credit limit". You can create a method on a rules object for each one of these rules.

Other than that, the majority of your business logic belongs in KBizObj.
