If you have to ask the question "should I do a CCNA or an ITIL qualification".....then you're asking the wrong question.
The real question is:
Do I want to do project management or technology?
With the follow up:
If I want to do technology, do I see it as a route to management greatness, or do I want to stay techy?
The best guys? Those will be the ones with a solid grounding in technology (i.e have programmed, built networks or whatever), have moved into architecture and design, then moved into management. So you end up with a manager who knows how it should be done, knows what a workable system looks like and can deliver it These guys are invaluable.
Most importantly, what type of organisation do you want to work for?
