B.2 Background

This system, being built for a government agency, consists of a number of off-the-shelf components (workflow, imaging, and accounting systems) integrated with proprietary business software. Its overall function is to enroll applicants into a retirement system. The business is triggered when an enrollment form is received. The form is scanned electronically using an enterprise scale imaging system and the original is sent to document storage. The type of form received indicates the business process the sender requested , and the system creates an instance of this process in the workflow system. The next available operator will be assigned this work and will access the document image from the integrated system if the client has an active account that is made available.
