The only time my group works with another group is if the investigation is so large (meaning the size of the location) we can not cover all the areas as fully as we would like. In those few cases we have asked a second team to join us. What normally happens is we cover our section, they cover theirs, then we switch. After we each get full copies of all teh data for review.
Of course we have asked a couple of groups to work with us, but things just havent worked out scheduling wise, and for other reasons.
It is different for me personally because I am part of a second group as well, as a guest investigator, and as a technical advisor. Very rarely am I not asked in on one of their investigations, and the lead/founder investigator and I colaborate on most everything the group does. Kind of weird, but it works
