This is not true of all CIOs. According to the Gartner report, "Gartner identifies four types of CIO: At-risk, transactional, partner and trusted ally." If you are the CFO, you want to collaborate with a trusted-ally type CIO to get the ERP system you want and the business needs. The other types are more likely to be comfortable sticking to talk of technical details and vendor choices in light of strained resources.
