Thanks for this reference. I'll definitely take a look at Asta. As for Excel: yes there are some advantages to Excel, but it is not particularly easy to handle numbered lists within it. We need to be able to easily over voice communications explain where the crewmembers should go as the plans change on the fly, i.e. "EV1 must perform page 36 steps 15-27 prior to EV2 performing page 34 steps 1-10."
