Without services, you cannot have an SOA. Furthermore, an SOA comprised of services with no business or organizational value is well nigh worthless. Therefore, getting your services right is essential. What are the right services? The right services support business and mission objectives. The right services are derived from your SOA strategy and align with your future direction. The right services support your SOA goals. The right services offer a balance between immediate value and long term investment. The right services should be reusable and shared to ensure rapid return on investment, short payback periods and cost avoidances.

Of course, to really ensure these are the right services, you must perform service modeling and design activities on the candidate services to achieve appropriate functional scope, encapsulated functionality, granularity, and reusability as well as assessing risk and business fit.
