Consider this scene from "Scientific Method": http://www.youtube.com/watch?v=y8-917vo9C8 How in the heck are there as many as thirteen departments on a ship as small as Voyager? And, why are they reporting to Tuvok? TNG seemed to suggest that department heads reported to Riker, not Data or Worf (second officer and chief of security, respectively). For that matter, how could there be thirteen departments on any Federation starship? What would they be? And, isn't security a department? So, isn't Tuvok a department head also? Why are department heads reporting to another department head? And, now we have fourteen departments on Voyager! Thoughts?
