Aka “Secret Santa”.
The idea of “relative sizing” can be applied in a lot of situations. Most first learn of the concept in agile when we do estimates of the size of work. When agile Teams require an estimate of the work, they often use Story Points, a measure of relative size, as an estimate. We use Story Points because it is faster than estimation of absolute amounts. And the data that results is often more accurate as well. The idea that we can gauge something that is bigger or smaller than something we have, that we can do it quickly, and that we can turn these the result into numbers if required (through affinity mapping) is not limited to job size. We can apply the concept to estimates of relative business size, relative risk, relative impact, relative whatever.
Relative sizing also does not have to be done in a single dimension. For example, at the same time that we estimate relative risk, we can also estimate relative impact, if we set up both a horizontal and vertical axis. The technique can be applied as both a single and dual dimensions.
When this approach is used you will see:
For relatively comparing the size of a single axis (for example, effort, value, criticality, risk, impact, opportunity, etc.):
If you want to do two variables, just create a horizontal and vertical axis. People place items of the wall commenting on both of these axis.
Here is an example laying out probability of risk and impact:
