Study Notes
Value and Risk of Creating an Enterprise Architecture
- Creating an EA program in an enterprise has both value and risk associated with it.
- The value of EA lies in its ability to bring together views of strategy, business, and technology, allowing an enterprise to see itself in current and future operating states.
Value of EA
- EA supports the modeling of different future operating scenarios, helping the enterprise respond to changes in the internal and external operating environment.
- EA establishes an integrated set of IT resource planning, decision-making, and implementation processes to identify and resolve performance gaps across the enterprise.
- EA promotes enterprise-wide thinking about resource utilization, replacing systems-level approaches to IT resource development.
- EA develops more efficient enterprise-wide common operating environments for business and technology, making an enterprise more agile and competitive.
Benefits of EA
- EA helps identify existing duplication in functional capability, generating additional savings.
- EA documentation helps identify current and future performance gaps, enabling the enterprise to be more proactive and cost-efficient in addressing solutions.
- EA enhances resource-planning capabilities and supports better decision-making through improved communication and reduced misunderstandings.
Risks of EA
- Creating an EA for an entire enterprise can be time-consuming, costly, and disruptive to business services.
- Developing detailed EA documentation can be time-consuming and costly.
- Hiring and/or training architects and supporting analysts, and the cost of EA documentation tools and on-line repositories, are additional cost elements.
- There is a risk that the EA will not be used by stakeholders if they do not buy-in to the concept of EA or its perceived value.
Measuring Costs and Benefits of EA
- The benefits of EA should outweigh the costs of doing an EA, or the program should not be established.
- An EA program can pay for itself by identifying combined solutions to business and technology requirements, and generating cost savings.
