This is often referred to as an information radiator, defined by the Agile Alliance as “the generic term for any of a number of handwritten, drawn, printed, or electronic displays which a team places in a highly visible location, so that all team members as well as passers-by can see the latest information at a glance: count of automated tests, velocity, incident reports, continuous integration status, and so on. This idea originated as part of the Toyota Production System.”
