!'''Product Owner''' '''Model.''' This model uses departmental clusters or business owners to govern distributed instances of enterprise solutions. This model leverages enterprise standards, product owners, departmental clusters, governance and oversight. This model may also leverage distributed technical infrastructure to support solution clusters

|'''Federated Model.''' This stand alone, or decentralized model allows departments to implement their own stack components, influenced by standards, using APIs via interoperability standards. Governance manages exemptions from the Standard; however, a decentralized enterprise with multiple service delivery methods and business units  may be successful in finding justifications for significant deviations for standards
