System Analyst / Requirements Engineer - Kuehne + Nagel

I work at Kuehne + Nagel for the KN FreightNet project in Hamburg since 2011. Originally from Venezuela, I joined the company as a software developer but now work as a requirements engineer, collaborating as well with the agile-coaching team with Retrospectives-moderation. Agile by nature, I consider fostering collaboration and communication in my team a key part of my work. I am passionate about continuous improvement and about always trying to find ways to optimize the team’s results in order to deliver as promised.

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

The next piece of software is to be developed by 2 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 deliver a date, so he takes 7 months as the average of the 2 teams. In this talk I will explain why average-based plans fail on average, then take a look at the psychological problems we humans have dealing with probabilities as a possible reason why we keep falling into the averages trap. Finally, I will show a way to avoid it when it comes to software development estimates.
