Adding parameters to an interface in IDM

Having located and established a business service within the Interface Design Model (IDM) component architecture, that service definition can be extended to include the inbound and outbound data parameters of the service. These parameters are captured during analysis as the input and output informational requirements of the use case from the definition of this service.

For each input of this use case, the following are added:

• New service parameter
• Name and definition
• Directionality specifier [in]
• Outbound parameters are added with specifier [out]

Where a given information requirement is passed in and then back out of a service, the qualifier [in out] is used.
