Can a Manager Be a Techie and Survive?

Though in an different perspective from my posting, the article that triggered it was this one.

Some people say that good managers should not be technical at all. Others say the exact opposite. I say: it depends...

Yes is true, throwing to much attention to technical issues can divert you from a broader management view. But it's also true that on some particular areas the technical baggage can help you creating the perspective view some managers lack.

And yes, as a general rule of thumb, managers should have their masters in management, not in technology. But don't we all know excellent managers that are still mad about technology?

One thing is for sure: when overlapping management and technical roles, be sure to "change your role hat" accordingly with what you are doing - messing this hats can and will be harmful to your projects.
