What does a job title mean?

I'm a Technical Manager, with a degree and a plethora of industry qualifications. I've worked hard to get where I am, and sacrificed things to do my degree (s) in my own time, financed by myself.

I've recently been on a course where there were a variety of my peers from technical co-ordinators, QA Managers & Technical Directors. What intrigues me, is that the technical co-ordinators are often far better informed and educated than Technical Directors! So how do you become a Technical Director? I mean, the ones I met had no formal qualifications, which I find hard to believe in this time and age, especially as the majority of them are maybe mid forties. There used to be a time that I'd have been impressed by someone who said they were Technical Director, now I'm suspicious on how they got there! What is a Senior Technical Manager? as the only technical person on site, does that make me senior?  Why does a company (that's not very big) need a half dozen Technical Managers? I know from the forum's, that technical people often disagree and I'd hate to have another two of me here! At least now I can change things at my own whim, without having to ask permission. I appreciate it would be nice to have someone to bounce ideas off, but I have you lot!

I think what I'm getting at is, that I obviously haven't slept with the right people over the years and this means I've had to work hard. Still, I suppose I have my integrity!
