Procedures

Each participant, whether on site or off site will be considered a particular 'player' in each of the two scenarios (use cases) selected.  The concept is that each site will be able to add to or modify the patient record and then send the complete record or a portion of it as requested, to the next provider. 

How closely should these be planned in advance?

Potential Problem Areas

  1. Date/Time Restrictions - Some participants may be using commercial or open source deployable applications that already have date/time detection limitations builtin for certain funtionalities.  Since will will be simulating a long period of time in a relatively short period of time; as well as doing this across multiple time zones.  What are the implications to the participating systems?  Should we schedule all systems to be set to UTC and have scheduled datetime changes at specific times?
  2. ??????
