The trap of averages. How to avoid it in software development estimates

The next piece of software is to be developed as quickly as possible by two teams and they now have to answer how long it’s going to take. Team A says 5-8 months and Team B 6-9 months. But the department head is under pressure to give a date. He decides to simply take 7 months as the average of the two teams and so the rest of the project plan ends up based on averages. Basing on the book „The Flaw of Averages,“ I will explain why average-based plans fail on average. I will take a look at the psychological problems that we humans have in dealing with probabilities as a possible reason why we keep falling into the averages trap. Finally, coming from the experiences gathered by two of the teams in my department, I will show a concrete alternative to avoid this trap at least when it comes to software development estimates.
