Right, "research potential options" is usually part of Crysis Management, which should precede any application of the DR procedures.
But there's a wide range for the scope of those procedures, they might go from switching to secondary servers to a full rebuild from data backups on tape. In some cases they might be the best option even if the system is easily recoverable (eg: if the DR procedure is faster than the recovery options).
Just the 'figuring out what the hell is going on' phase can take several hours, if you can get the DR system up in less than that it's certainly a good idea to roll it out. And if it turns out that you can fix the main system with a couple of lines of code that's great, but noone should be getting chastised for switching the DR system on to keep the business going while the main machines are borked.
