Use Java to build the service and SSL to encrypt the transport.

Use Java.security to encrypt payload while making sure that service consumers are on a secure and reliable network.

Use WS-I to promote interoperability while using the WS-Security family of services to secure web services.

Use WS-Policy and WS-Reliable Messaging to support delivery-based quality of service.

Choose a different technology and automatically score the Service as having a high technology capability inhibitor score

Reflect the cost of the resources in the weighting for the skill set Impact inhibitor score

Reduce the potential reuse level of the Service because It may be difficult to find skills to update and manage the Service in the future

You cannot score this Service without the skills being available

This availability of the skill is too subjective to be possible to score

The capabilities in a product are identified and then the product is mapped to the architecture based on those capabilities. A product can map to more than one layer of the architecture.

The capabilities in a product are identified and then the product mapped to the architecture based on those capabilities. The product is mapped to the layer of the architecture where the most capabilities lie.

A product is compared to the Oracle products that are already mapped onto the architecture. The product is mapped onto the architecture as a replacement for the most similar Grade product,

A product is compared to the Oracle products that are already mapped onto the architecture. If the product provides all the capabilities of an Oracle product, the product replaces that Oracle product.

Products are not directly mapped onto the architecture; only the capabilities provided by the products are mapped onto the architecture.

A Service portfolio provides a single location for storing Service meta-data, software relationships, and metrics in order to apply governance policies and systemetise reuse.

A Service portfolio provides a singlesoftware library from which artifacts can be deployed and versioned.

A Service portfolio provides a runtime view of the Services so that the right Service may be looked up and consumed in an environment.

A Service portfolio contains all the software artifacts that will be developed by a project so that project managers can track their lifecycle through the project.

Cycles are permitted in the model so as to show exchanges of Information between businessfunctions.

The model is navigated by organizational structure.

Each level in the functional model has a specific designation with respect to functionalgranularity.

Each decreasing level is finer grained with respect to functional representation when compared tothe level(s) above.

Duplicate functions can appear in the model because that will help discover opportunities where Service Candidates can be reused.
