Service Reuse

One key aspect of a SOA Roadmap is to guide the evolution of an IT organization through the stages of increasing reuse maturity. This serves the ultimate trinity of purpose:

• Reduce project cost.
• Improve time to market.
• Better align IT with the business.

We are using a bubble-chart from one of our customer engagements to illustrate service reuse across projects that are part of a SOA:

• The vertical axis in the chart indicates to what degree a project contributes to the SOA, either by providing reusable services or by enhancing the architecture and the development processes towards increased SOA Maturity.
• The horizontal axis shows the level of reuse of existing services in a particular project.
• The size of a bubble is a measure of the cost of that project.
