A Framework for Web Services Composition Modeling Process.pdf

1、The modeling business processes still remains the responsibility of ITpersonnel. This has produced a gap between business process modelingtechnology and business users, who are the actual authors of businessprocesses.

2、 Bridging this gap has become a major concern in utilizing the fullpotential of information technology in businesses and it can swing control ofprocesses from IT departments to business departments, which in turn, leadst
