Communications-enabled application

A communications enabled application (CEA) is a set of information technology (IT) components and communication technology components that are integrated using a particular service-oriented architecture (SOA) to increase the productivity of an organization and/or improve the quality of users' experiences.
Communication enablement adds real-time networking functionality to an IT application. Providing communications capability to an IT application:
What distinguishes a CEA from other software applications is its intrinsic reliance upon communications technologies to accomplish its objectives. A CEA depends on real-time networking capabilities together with such network oriented functions as location, presence, proximity, and identity. 
Another distinguishing characteristic of a CEA is the implicit assumption that network services will be available as callable services within the SOA frameworks from which the CEA is constructed. To provide callable services, the network services which are available today must be made virtual and component-like.
CEAs apply to business processes as well as instances where no obvious business process which requires improvement exists (e.g., games, entertainment video). CEAs that apply to business processes are referred to as communications enabled business processes or communications enabled business solutions.

CEA are important for at least four reasons:
