I'd rather have a manager who knew how to manage than a techy who didn't
A manager doesn't have to be all knowing, that's what his team is for, to provide him with the information required for him to take the lead.
Obviously if the manager can't manage his way out a paper bag, or is unable to take anything in as well then yes that's rather useless!
And many people do transition from Techy to manager but not everyone is up to it.
Very true. Ive always found though that it does help to have a manager who can actually take on board any techy stuff you relate to them and actually know what to do with the knowledge.
My manager at my previous firm clearly did not know her **** from her elbow when it came to IT. I used to attend IT champions meetings with her, the IT Director and some nominated users (lawyers) in order to better the profile of IT. Suffice to say that when she opened her mouth in the meetings she always managed to make the whole of IT look stupid. On top of that she complained that she did not have the time to micro manage us and therefore hired a team leader for a team of 3!
If she hadnt been buggering off to IT and legal conferences 3 times a week then maybe she WOULD have the time! Bit of a no brainer really

Worst scenario was when it was just a meeting between her, the team leader and myself. I threw some ideas on the table which they liked and when she pitched these to the director she repeated everything I said word for word. To add insult to injury I was told she convinced the director that they were her own original ideas!
Suffice to say I am no longer working there and I am no longer in legal IT working for a complete pleb of a manager!
