A successful EA strategy takes into account the latest innovations in business processes, organizational structures, information systems, and technologies.
It promotes the use of standardized language and best practices across the organization, making it easier to integrate or eliminate processes as needed.
Key Benefits
- Drives innovation by keeping up with the latest technological trends.
- Streamlines business processes for greater efficiency.
- Enhances the reliability and timeliness of business information.
5. Ensuring Executive and Stakeholder Buy-In
Implementing this architecture strategy requires the support of executives and stakeholders. Their buy-in is important for ensuring that the strategy is adopted across the organization and that it has the necessary resources for successful implementation.
Key Benefits
- Facilitates alignment between IT and business leadership.
- Ensures adequate funding and resources for EA initiatives.
- Promotes a culture of continuous improvement and innovation.
Steps
There are eight steps in the process:
Viewpoints
It contains four viewpoints. They are
- The business perspective defines day-to-day processes and standards of business.
- The application perspective defines relations between organizational processes and standards.
- The information perspective defines raw data like databases, images, files, etc.
- The technology perspective defines hardware and software, such as operating systems, networking tools, etc.
Framework
A variety of EA frameworks can be used for enterprise architecture. More popular frameworks include the Zachman Framework, the TOGAF Framework, and the MODAF Framework.
Zachman Framework
The Zachman Framework consists of six steps:
- Define the problem or opportunity
- Generate alternative solutions
- Select a preferred solution
- Develop a blueprint or model of the preferred solution
- Implement the blueprint or model
- Monitor and adjust the implementation as needed
TOGAF Framework
The TOGAF Framework consists of seven steps:
- Define enterprise goals and objectives
- Create an enterprise framework
- When designing or redesigning your enterprise architecture, you need to think about the different business processes, information systems, and infrastructure that will be necessary.
- Develop a detailed design for the components identified in step three. Then, consider how each component should work individually and interact with other enterprise components. Be sure to include any relevant non-functional requirements such as security, scalability, or performance requirements—document things like data models, user interface designs (UI) specifications, etc.
- Develop a transition plan that identifies what needs to change from the current state to the future described in the target enterprise architecture model.
- Implement the enterprise architecture plan.
- Validate enterprise architecture by checking that what was designed and implemented meets enterprise goals
MODAF Framework
The MODAF Framework consists of five steps:
- Define what is to be modeled
- Construct the enterprise model
- Model elements and relationships within the enterprise model
- Derive system requirements from the enterprise model
- Implement the system requirements

They are in charge of developing and maintaining the company’s architecture framework, identifying components that need to be designed or redesigned, producing detailed designs for these components, and ensuring that the corporate architecture is adequate.
Enterprise IT personnel
They will implement it. Therefore, when designing this architecture, one should always consult with enterprise IT personnel to ensure that what is designed can be implemented and will meet enterprise needs.
Business analysts
They should be involved in this because they help define EA’s enterprise requirements to build their models.
Other enterprise stakeholders
People who should help create the architecture for an enterprise include enterprise architects, IT personnel, business analysts, and enterprise customers, suppliers, and shareholders whenever possible.
For example, while they may not be required to help build out the architecture’s components, such as business processes or enterprise applications, enterprise customers and enterprise suppliers can provide valuable feedback that should be considered by enterprise architects when designing the architecture.
