Enterprise Solutions may be governed using three general models that provide relative advantages in terms of addressing technical debt, minimizing total cost of ownership, maximizing use of talent, maximizing consistency of technology and business processes, and optimizing infrastructure.   

Enterprise Solutions may be governed using three general models that provide relative advantages in terms of addressing technical debt, minimizing total cost of ownership, maximizing use of talent, maximizing consistency of technology and business processes, and optimizing infrastructure.   

# '''Enterprise Service Provider Model.''' This model provides all services to the entire Enterprise in a consolidated manner, governed by a centralized authority, and is fully integrated across all instances.

# '''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.
