Misfits as signals
A misfit is the gap between what a product assumes and what its people need. Products already produce signals of their misfits; they are just scattered across settings, tickets and workarounds.
The model
Three signals, one object. A changed setting is a quiet misfit. A repeated ticket is a loud one. A workaround is a misfit someone has already solved for themselves.
What it predicts
The misfits worth fixing are the ones that recur across people, not the ones that are loudest this week.
