There was a severe lack of editorial direction there. We wound up with two different approaches by the six authors.
Susan Wright, Peter David, and I all did separate stories focusing on the captain characters. One Small Step, Cold Wars, and Demons of Air and Darkness all came to a conclusion, and then "One Giant Leap," "Death After Life," and "Horn and Ivory" were separate novellas that specifically followed Kirk, Calhoun & Shelby, and Kira. I don't know about Peter or Susan, but I actually wrote "H&I" several months after I finished DOAAD.
However, Diane Carey, Christie Golden, and Robert Greenberger all just lopped the last few chapters off Chainmail, No Man's Land, and Doors Into Chaos.
I think it would've been better if we all took the same approach that Susan, Peter, and I did, with the exception of Bob, who was tasked with bringing the whole storyline to a conclusion in "The Other Side."
