Do CIOs and CMO like each other? While they could not be more different - stereotypically, the CIO is analytical, cautious, compliance-oriented and cost conscious while the CMO is action-oriented, outgoing, customer-facing and opportunistic - they actually do.
A CIO.com survey in May found that most CIOs rate their relationship with CMOs as good to excellent, which makes me think that they are wary about each other, not hostile. After all, both are adults. It should be noted that 4% more CMO's rated their CIO relationships as "excellent" than the other way around (see chart).
