The use of an enterprise architecture (EA) framework BEST supports IT governance by providing:

An enterprise architecture (EA) framework is a set of principles, guidelines, standards, and tools that help design, plan, implement, and govern the IT architecture of an enterprise. One of themain benefits of using an EA framework is that it provides reference models to align IT with business, such as the Business Architecture, the Information Systems Architecture, and the Technology Architecture. These models help define the business vision, goals, processes, information, and technology requirements of the enterprise, and ensure that they are consistent and coherent across the organization. By using an EA framework, IT governance can ensure that IT supports the business strategy, delivers value, manages risks, and optimizes resources. References:
