If you're working in an environment where you have more than one portal, a lot of organizations do, it's critical you have human and automated governance policies in place to control your content or you'll deliver incorrect information to your users which can lead to many bad results.
It's important to create and leverage one core governance model that controls every portal in the organization or your time spent on governing one portal will be of little value in a matter of months. It will also cause disruption and resistance in users of the other portals. All of this together will create a cascade of misinformation and non-compliance that could cause major problems for you and your organization.
