For the most part, running the study means executing the sessions. However, part of running an efficient and effective study is redirecting when needed; this can mean aborting a session when necessary, or deciding not to run certain sessions if they are not going to add any value.
The moderator runs the session, yet the entire support team must be on deck behind the scenes; the technician must be available, in case something technical goes wrong during the session; for instance, if the moderating software crashes or the internet connection becomes unstable. The schedule organizer must be in contact with the moderator and observers, to inform them of last-minute participant changes.
