Subject: BQoS Issue: Performance:QualityAssertion
Hi Everyone, (Note: I'll repeat this intro where it applies to the issues I bring up.) I have not had time to address these specs as I would have preferred, but as I am working through the process of diagramming the SOA Reference Architecture Foundation due to be released for Public Review in July (hopefully), I do have time to bring up a few crossover issues that will help align and coordinate the use of the RAF to develop specific, concrete solution architectures. This Issue applies to the BQoS Specification for the Performance category. I think we should include a formal mechanism for Service Providers to assert the specific Qualities of their services. Because this is something that I expect will evolve over time, I don't have suggestions at this time for specific subcategories of Quality. I think it would be wise to include this as a free text element at first. Later we may have subcategories that arise, but I wouldn't want to wait until we define those in order to get feedback from our audience on what they want to assert about their services. For instance, a conference management service might assert: "We deliver a high percentage of decision makers and decision influencers." This kind of assertion sets the foundation for a rating service to say something like, "Acme Conference Management delivered an audience for Conference X in which only 35% of attendees could be confirmed as decision makers." Because many Quality Assertions may be subjective (e..g. "a good time will be had by all"), without such an assertion, rating services and potential Service Consumers will not have a basis against which to evaluate services. The point is that even subjective Quality Assertions can be evaluated by ratings services, even if we can assign an objective unit of measure. By providing Service Providers with a BQoS: Performance:QualityAssertion, I think we can begin to make better assessments of services.
