nelkins: So I did lately, but I found out that 2.5 works better. I suspect top management for putting us middle ones into time troubles on purpose... Just to know how we can handle it. So we have evolved :)
Sometimes you have to factor in stupidity or you end up with this.
Boss: How long will job A take to do?
Me: 2 weeks worth of work.
Boss: Drop job A and do B, it has become high priority.
Another week later
Boss: Thats 2 weeks, is job A finished?
Me: No. I said it will take two weeks worth of work to do.
Boss: But its been two weeks.
Me: Yes, but you've only let me work on it for one. Its not like putting it in the oven and letting it bake on its own for two weeks unattended.
They struggle to see the problem. Better to double the estimate and occasionally become a miracle worker.
