Softgoal Interdependency Graph

Performance

quick meetingdetermination

quick info.sharing

quick between dete and actual

Usability

accommodate decentralized requests

physical consistency

- -

Extensibility

handle explicit priorities among dates in pref. sets

handle explicit dependencies between meeting date and meeting location

variations in date formats, address formats, interface language

participation through delegation

-+

Customizability

Private &Professional meetings

Customizable Flexibility

Rescheduling dynamically

accommodate evolving data

Flexible

Security

Softgoal Interdependency Graph NFRs

non-privileged participant should not be aware of constraints stated by other participants
