The BIA isn’t dead, but its original form has been unrecognizably beaten up. Reliance on an inexact methodology doesn’t make BIA’s useless. To paraphrase Mark Twain: the death of the BIA has been greatly exaggerated.
Once, Business Impact Analyses did simply that: analyzed the impact of disrupted functions and systems to rank organizational criticality and recovery prioritization. BIA’s that stay true to their original intent can be very valuable.
