I know that there were quite a few problems above me. Lack of leadership carries far and wide and there was a disconnect between what the products did and what the management thought it did. Lack of money (think lack of compensation, lack of tools, lack of time for anything but immediate returns) did not help either. I do keep questioning whether I was doing all the wrong things or if I was put in a situation designed for me to fail, or perhaps both.
After I left I understand the company hired three different people to replace me: a manager, a dev lead, and a support engineer. I suppose that's some kind of a sign that I was trying to do too many things at once. Most of the engineering team also left after I did. The least I could do is give them the great recommendations they all deserved so all of them moved onto exciting new pastures. However, I cannot help but feel like I failed at this task that I felt sure I could tackle and I don't understand why.
Please excuse the rant. These types of topics always trigger those same feelings in me.
Edit: now I work as a developer on 2-3 person teams. I have no reports. I get to be productive again! I can write code that doesn't have to suck to compensate for poorly chosen deadlines. This is good for the soul. I do miss leading a team though; not managing but really leading. One of my proudest moments was when I was allowed to follow a system of estimates and sprints I put together and for 8 weeks my team delivered on schedule and exactly what was promised. That was one of my more joyful moments.
