Scrum is simple and hard. So is losing weigth for the majority of people.
The secret of losing weight is that you eat less. That is that simple, but doing it is hard.We can apply empirical process control to control one’s weight. Let’s have a daily weighting every morning to create a burn down chart of your body mass. Then you tell your group of peers what did you actually eat yesterday and what are you planning to eat today. This is basically how weightwatchers do it.
Eating less is hard and so is software development. Deciding what do (that is called prioritizing), limiting work to capacity under pressure and keeping the commitment are tough things to do in real life.
Disclosure: My own weight is normal and has always been.
