Table 7 - The CBDI Roadmap Framework - Projects Steam

Many organizations will maintain recommended project profiles for project teams to then customize as appropriate. Existing project profiles will require customization and there are five important profiles that may be important to consider and plan for.

Experimental and early learning

Exploratory activity that is undertaken either by individuals of individual project teams. No significant reliance on shared infrastructure.

Project level services

Web Services created as interoperability mechanisms within the confines of a project. Relatively minimal requirement for formality of process, for example separation of supplier and consumer, certification etc

Implementation Based Services

Web Services used as integration layer for existing and legacy applications.

Enterprise level services

Web Services created for reuse across the enterprise.

Services are products

Web Services form an integral part of one or more core business product offerings.
