I was learning about how to estimate software development effort, and would like to know how successful enterprises estimate their projects. How they do to know how much time a system will spend to be developed? What are the modern techniques to do this? What are the techniques used by these modern enterprises?

Some articles and interviews of employees of those enterprises would be interesting.

I asked on Project Management site of StackExchange too.
