QuestionQ57Verified/The TOGAF Standard, Version 9.2Copy linkReport a problemAsk AstroTutorSave questionBased on TOGAF, which of the following is the most appropriate answer?ASince some artifacts will now require specific measurements and additional data will be needed to support the performance objectives linked to these measurements, you recommend that the motivation and governance extensions of the TOGAF 9 Content Metamodel are used. Using these extensions will allow modeling the goals, objectives and drivers for the architecture, linking them to service levels and more detailed governance models. This will also enable the ability to re-use existing profiles, customizing them for the various service contracts involved.BYou recommend all of the TOGAF 9 Content Metamodel extensions be incorporated into the Architecture Content Metamodel. The full Content Metamodel will enable the EA team to capture and categorize all the important additional data needed to support the performance and measurement objectives linked to these artifacts. Once the new repository content has been implemented, on-demand queries can be used to generate a customized governance stakeholder view that isolates the artifacts and data needed to assess measurement for any particular service. If this view is found to be inadequate for the governance concerns, the service models within those artifacts can be expanded.CSince this case requires extensions of the modeling and data details of the service, this is best done by using the services extension of the TOGAF 9 Content Metamodel. By using this extension, the service model is no longer constrained by what is expected in typical business service definitions, allowing more flexibility for adding customized models to support the more stringent measurement requirements. The services extension can also be used to map terminology between the business services and the application components.DTo support the type of stringent performance measurements needed for the more detailed governance views required for the upgraded system, the interfaces to the communication and network layer of the architecture must be highly visible at the application level. To accommodate the proper development of this, a Communications Engineering view should be created from the infrastructure extension models of the TOGAF Content Metamodel. This view will allow architects to align the required performance measurement communications across the system.Show AnswerAnswerExplanationThe TOGAF 9 Governance extension adds Measure, Service Quality, and Contract entities. These allow performance objectives to be connected to services, reusable service-level profiles to be defined, and functional and non-functional service requirements to be formalized in contracts—supporting verification of critical service performance and governance of required service levels.Learn moreUsing TOGAF to Define and Govern Service-Oriented ArchitecturesTOGAF 9 DocumentationShow comments6Show commentsCommunity DiscussionNo comments yet.
