One of the things I love about XP (this is a principle of Scrum also) is the concept of Sustainable Pace. Ron Jeffries aptly documents this on his site in the following text:
Growing up, I had a dream of being a photographer. I didn’t know why I was drawn to it, but it was something I wanted to do. I bought my first camera when I was 10 years old – it was a Kodak Disc camera. My second camera was a Konica TC Autoreflex – it was my first real camera. I worked a summer for my dad at the wonderful rate of $2.50 per hour – I thought it was good for 11 years old. As I got older, I became more into photography.
The daily standup meeting, or daily scrum, often does not get the respect it deserves. Done correctly, daily standup meetings keep everyone on the same page for the daily deliveries and moving as one toward the sprint goal.
