# Manage Portfolio domain in the CSDM model

The Manage Portfolio domain is a layer on top of the CSDM conceptual model that interacts with the other CSDM domains. The typical user, a service owner, might be responsible for services in more than one domain.

\[Omitted image "domain-manage-portfolio.png"\] Alt text: Manage Portfolio domain of the CSDM framework.

For example, in the Service Consumption domain, the service owner for Human Resources \(HR\) might be financially responsible for the business application that provides HR services. The service owner might also manage the HR application instances \(known as service instances or systems\) and might also be accountable for the impact the application has on the business.

Because of these additional responsibilities, CSDM enables service owners to oversee business applications and their deployed instances. This visibility enables service owners to perform their duties and meet their responsibilities.
