SOLUTION SERVICE: PHYSICAL SOFTWARE ASSET. A solution service is a tangible software
asset, constructed by business and technology development teams, that has concluded its development
life cycle and is deployed and integrated in a production environment. This asset may
be a custom-built software product designed in house, an acquired third-party vendor solution
package, or a component custom built by an outsourcing firm. It is the ultimate deliverable of a
software development process. Regardless of its origin, we typically employ a solution service to
participate in a business or a technological solution devised by the service-oriented modeling practice.
The following section, which elaborates on the aspects of service-oriented metamorphosis,
