Probably the most important relationship a CIO has is with the CEO. A good relationship between these two people means the business understands the potential benefits the IT team can deliver to the rest of the business. In turn, the IT strategy gets the buy-in from the visionary head of the company — hopefully the person who the other business-line heads will fall in behind.
To lay the foundations for the best possible relationship, the CIO has to fulfill certain expectations from the CEO, according to Stephen Miles, at headhunters Heidrick & Struggles. Many of them resonate closely with the skills the CEO has to posess, but others are distinctly complementary.
