| Abstract: |
How do we decide the functionality of a software service? The Service Portfolio Plan has identified the services required, and defined their broad responsibilities. Next, we need to determine the specific requirements for each service: the actual functions (operations) it needs to offer, and any non-standard quality requirements.
This report introduces techniques for formulating these requirements, which are initially derived from the immediate needs of the software solution projects that are underway. What gets built (or acquired from external sources) has to serve the needs of these projects. At the same time, the Service Provisioners must aim to address the needs of future Service Consumers and must deliver the flexibility needed to cope with the inevitable changes to the prevailing business environment. If necessary, each service’s functionality is delivered incrementally; the service content is then extended in future releases.

| Backgrounder: |
This is the second article in a five part series that provides guidance on how to develop software services for long-term value while addressing the immediate needs of current projects.
Part 1 covered Service Planning – identifying the software services an enterprise should acquire in the long-term.
Part 2 covers Service Refinement – in which the specific functional requirements for services are uncovered:
Part 2a describes techniques for driving the service details from underway Software Solution projects.
Part 2b will consider situations in which the service providers take the lead in defining requirements.
Part 3 will address Service Specification – preparing a thorough definition of service function and quality, to be used by implementers, testers, consumers and operations staff.
Part 4 will concern Service Delivery – the activities required to take a service from specification to deployment. |
