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”)

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.
