Why are software schedules so hard to define?
I often need to explain to senior management why software estimation is so hard, and why our preliminary estimates are often so far out. I suspect some want to know why it is not mathematically precise engineering, like building a bridge.
You can help me by listing a few dot points relevant to this subject. Many thanks!
