Ask any up and coming developer what they would like to do in the next year or so and you'll invariably hear, I'd like to become a Development Team Leader Hopefully most will have actually considered the change of role and be looking for new challenges and ways to contribute more to their chosen profession. However, for some this is an automatic response to a question that is particularly difficult to answer in an industry with no clear career path. For others it's simply a way to move up the pay scale.
In over 20 years, I have never wanted to be a team or project leader. To me, that requires a very different set of talents - management and people skills first and foremost.
