A. Change the SOA Services to bypass the Mediation Layer when calling other SOA Services. The Mediation Layer should be used only between the clients and the SOA Services. The Mediation Layer should not be used between SOA Services.

B. The developers are accurately following the SOI architecture. Reducing the latency will require that some of the SOI architecture concepts be relaxed or violated.

C. Remove all data transformation from the Mediation Layer because data transformations are too computationally expensive, where required, change the interface of the SOA Services to use a single data model so that data transformations are not needed.

D. Allow clients and SOA Services to use large-granularity operations. Each operation on the Business Process Service should return an entire data entity or multiple data entities. This reduces the number of client calls required and, therefore, the overall latency.
