While developing the business context of an enterprise architecture (EA) program, enterprises are required to address certain key issues. They must first review the critical artifacts that make up the business context and learn how to develop a common requirements vision (CRV). The consumer of the total business context package also needs to be understood. Many first time EA teams face the challenge of realizing that the streams of work outside the creation of EA artifacts are important because without them enterprise architecture (EA) program doesn’t get any value.
Creating a CRV
CRV directs the way to an enterprise architecture (EA) program. To be an effective linkage, a CRV must be completed with the participation of business representation, not just IT professionals.
While creating the CRV, enterprises should capture, document, and examine the matrix of relationships between trends, strategies, business processes, and IT requirements. To expedite this process, a top-down approach with minimal number of approvals is desirable.
For a fast-path approach the enterprise architecture (EA) program team should create the mock-up and then with approval from the CIO and IT leadership team hold validation meeting of business and IT managements. The business and IT management group that approves the deliverable must be the same group that helps guide IT investment decisions in the company.
Laying the principles
After conceiving the CRV, next thing is to lay the principles. These are the critical links between the requirements from the CRV and the guidance given to all modeling activities. If principles are missing, the resulting enterprise architecture (EA) advice can be weak.
Principles can be created through a SWOT analysis, by understanding best practices, engaging in executive leadership and enterprise architecture (EA) review board, and by obtaining sign-off from IT and LOB staff.
Root anchor model
All the business processes, information, and technologies are put on top of a root anchor model that may have complexities for governance and enterprise architecture (EA). Enterprises should plan, design, and execute a federated plan to bring clarity to the span of control for enterprise architecture (EA) program, enterprise program management, and IT portfolio management.
Post this, the principles and models are linked to CRV that guides the future state.
Businesses must ensure that the investment decision makers sign off on the CRV, anchor models, and principles that make up the business context package for the enterprise architecture (EA) program. They should enact a governance process for conflict resolution that ends with the same decision makers who have signed off on the business context package.
