I think riding assignments promote efficiency on the firegoround and lends to a members feeling of "having something to do" even on mundane alarms like automatic alarms. I agree that the volunteers do have a more difficult time filing assignment slots because of fluctuation of available manpower at any given time of the day or night, but shame on us for not exploiting the opportunity when it does arise. I do try to do this by assigning positions whenever our department responds with a crew that has been pre-determined by the detail. Stand-by's,special details etc. I think that this gives the members an opportunity to see how riding assignment theory works and helps them implement it faster when responding to incidents where the luxury of pre-determination isn't available.
