Syndrome resolution - How does the diagnostician know whether a symptom is related to an existing condition or is of entirely new origin.
For example,

• "Server Failure for usabc.ca.com" - 12:30pm - the first symptom
• "Server Failure for usabc.ca.com" - 12:31pm - redundant symptom
• Usabc.ca.com gets fixed
• "Server Failure for usabc.ca.com" - 12:32pm - another instance of the problem
  (unrelated to the original)

Original notes:
Dave: Prescription "duration" is of some assistance to the diagnostician.
Abdi: Duration is a guide, but not enough. We need a "success" symptom to close the case.
Paul: What if the practitioner notifies when the prescription has completed. Any related symptoms thereafter could be considered a new incident.
Dave: Some prescriptions will be "fire and forget". The prescription might be complete, but we can't know when the effects of the prescriptions will be complete.

Alvin framed this debate as "Interoperability/Composability" versus "Implementation/Optimization".
