Is it a Pega best practice to create a separate application for enterprise layer, and then have your application 'built on' top of it?

e.g.

EnterpriseApp (contains rulesets - Org, OrgInt)

MyApp is built on EnterpriseApp

I think this will allow the build a robust set of enterprise assets and EnterpriseApp can be reused by other applications in the same organization.  COE typically owns the enterprise application.

Please leave any feedback.
