    Define Business objectives: First, you need to define the core business objectives of the organization. These goals should be clear, measurable and achievable.
    Analyze business processes: Analyze business processes within an organization to understand the collaboration between departments and employees, as well as key nodes and decision points in the process.
    Design operational model: Design an operational model based on the results of business process analysis. The model should include the various departments and employees within the organization, as well as the collaboration between them, the allocation of responsibilities, resource utilization, and decision making.
    Develop an implementation plan: To ensure the effective implementation of the operational model, a detailed implementation plan needs to be developed. The plan should include things like timetables, resource allocation, training plans, etc.
    Implementation operation model: Implement the operation model step by step according to the implementation plan. This may require communication and coordination with departments and employees to ensure they understand and follow the new way of operating.
    Monitoring and optimization: After the operational model is implemented, it needs to be continuously monitored and optimized. Collect and analyze data to understand the health of operational models, identify problems, and make improvements.
    Implementing operational models through enterprise architecture can help organizations better understand and optimize their internal operational processes, improve efficiency and quality, and achieve business goals. At the same time, operational models can also provide an organization with a clear frame of reference to help departments and employees understand their roles and responsibilities in the organization and how to collaborate with other departments and employees.

    The realm of enterprise architecture (EA) and its critical role in implementing an organization’s operating model is the way to achieve strategic objectives. On constructing a solid foundation for business execution through a well-defined enterprise architecture, which involves making strategic decisions about process standardization and integration. This foundation is instrumental in automating core business processes and establishing an IT infrastructure that supports the firm’s core capabilities.
    1. Operating Model: This is defined by the necessary level of business process integration and standardization required to deliver goods and services to customers, which in turn dictates how the company will operate.
    2. Enterprise Architecture: Described as the organizing logic for business processes and IT infrastructure, the enterprise architecture reflects the company’s operating model requirements. It provides a long-term perspective of the company’s processes, systems, and technologies, enabling individual projects to build capabilities that align with the company’s strategic vision.
    3. IT Engagement Model: This governance mechanism ensures that both business and IT projects meet local and companywide objectives, aligning project solutions with the enterprise architecture and coordinating decisions across various organizational levels.
    The authors argue that a well-implemented enterprise architecture can significantly enhance a company’s profitability, time to market, and strategic execution, and even reduce IT costs. They emphasize that the architecture’s value lies not just in its alignment with current strategies but in its ability to adapt and grow with the company’s evolving needs and objectives​​​​.
