Darn you sound like you work with me. And I swear to almighty god it is never my fault. A bunch of idiots get together and promise that I will deliver this piece of software at this date, without inviting me along to the meeting. Then, they write the specs (shouldn't it be the other way round at this point?). In most cases, the specs are incomplete and they want me to start while they are still finalizing stuff. I go tell them about a roadblock, and that they should revise the deadline and they tell me I should go ask someone else how to do it as if I am incompetent. And they always think bringing in more developers would make things go faster. Damn I am beginning to lose my cool just writing this.
