There are many concrete examples where the productivity of a programmer may be positive or negative.

For example: How many more tasks did you complete on average? How much time did you require the assistance of your colleagues? How many times per day do you interrupt other developers and prevent them from doing their job?

So the productivity multiplier is either over 1x or under 1x. When you multiply it up together for all the members of your team, and you normalize so that the lowest multiplier is 1x, you might realize that in fact some co-workers can be 100x more productive than others.
