I like Schratboys reply, just might add my comments. Yes, CIOs should do all that, now, even in a decent size company nobody has time for all of it. Maybe it's just me but there was a time when companies (CIOs) asked someone to solve business problems, nowadays it seems that, as Schratboy says, they are looking canned, well marketed, vendor special and depend products. Instead of creating a security, network, cloud, application, whatever solution the CIOs seem to asking someone to match Symatec, Cisco, Sun, SAP, Java, .NET, etc to their business even if it would be the most incompatible or the last best solution in some other way to the real problem(s) they have. In other words, some think changing the company business based on tools they use?

I don't know if it is egos, inexperience, free lunches, or some other aspect affecting the decisions but it really is causing very interesting and conflicting infrastructures to be built. I have seen / participated even big corporate IT merges which have gone both two ways - very smoothly and successfully when handled in business way, down to the tubes when letting the technology and marketing fad to take over.

Yes, CIO has to do business solutions or get them done based on corporate business goals, otherwise there is always a big and expensive cleanup waiting in future.
