Change the Representation
Is this actually small, or does it only look small in the representation I'm using?
Situation
Two people describe the same change as radically different in size or complexity.
The idea
Something can be small at one interface and large inside the system—or technically difficult while almost irrelevant to the user.

Watch for
A more complicated representation isn't automatically the more relevant one. Ask which representation matters for the decision.
