When a software project starts, and we’ve put considerable effort into the planning tasks, we feel the project is under control. Or “in control”. However, that’s fundamentally wrong. I tried to come up with a way to describe how I understand control in software projects, to illustrate the need and applicability of the empirical management …
“I’m afraid we might lose all these good ideas!” This is a phrase I hear very often when facilitating a Vision and Backlog session with the teams I work with. This is true for software teams as well as for business teams and mixed business + development teams. The fear of losing a good idea …

The fact is that a task does not have an intrinsic duration, it has a duration that …

The second part (“estimates don’t limit costs”), is self-evident. Anyone looking at the track record of software projects will see the evidence. …
I was watching a video of @nntaleb on youtube and it became obvious to me why scheduling / estimating is a bad idea for a Software Project. Here’s my take on it. Have you ever been HOURS early arriving from a flight? No. Have you been HOURS late? Sure. Happens all the time. I’m writing …
Before we start, I’d like to thank to Neil Killick and Woody Zuill for inspiring this technique with their work. Sit down. Let’s estimate This is not a good start of a meeting for many of us. Asking for estimates may be an easy thing to do, but going through the process of estimating Stories …
