Universal Containers has the following requirements:
* The Commercial Account and Consumer Account support departments should not collaborate.
* The Commercial and Consumer sales users roll up to the same VP of Sales, but there should be no collaboration between sales departments.
* The Commercial sales department should share its customers with the Commercial support department.
* The Consumer sales department shares its customers with the Consumer support department.
* The Commercial and Consumer support departments roll up to the same Support Director.
* The sales departments will remain the Account Owner for the Accounts that they sell to.
