Found a great article about software estimation. Something in software development that still bothers me somehow. Nevertheless we all know it is somehow essential.

Let’s take a hike on the coast from San Francisco to Los Angeles to visit our friends in Newport Beach. I’ll whip out my map and draw our route down the coast … The line is about 400 miles long; we can walk 4 miles per hour for 10 hours per day, so we’ll be there in 10 days. We call our friends and book dinner for next Sunday night, when we will roll in triumphantly at 6 p.m.
