Oh, ok. I think it would be doable. If you're the head of all of IT, I would find positions or advisors for software, hardware, and security. Something like 'software process champion' or the subdivision head of software. Hopefully there are knowledgeable people internally that could fill that type of role.

I think the most important thing as a leader is creating a network of advisors to give you thoughtful advice, and then being able to weigh the options and even synthesize your own. There are plenty of consultants and research groups (Gartner etc) that can also be helpful in large-scale transformations.
