© 2002 Oak Grove Systems – Assumptions Objective: Hyper-efficiency Mission: Eliminate “friction” resulting from intellectual decay. Strategy: Automate “management”. Tactics: Web Services + Workflow = Enterprise Orchestration “Programming the Enterprise”

© 2002 Oak Grove Systems – Key Issues Common User/Permission Management Locating intersection of process, application, & data Architecture supports recombination at the logic level (approach to modularity). Recognize “true” process –(example: override) Modular processes (“Flowlets”)

© 2002 Oak Grove Systems – Solutions Use external, multi-source resolver for user management; encapsulate permissions with each app module. Application context. Exposed services should be self contained. View “workflow” as a logic abstraction layer.
