Anything that interrupts the team or disturbs the flow of work within an iteration/sprint is called Noise. It causes significant disturbance within a Team, and causes lack of focus on delivery, ultimately leading to delivery failure.
Early 13th century,derived from “loud outcry”,from Old French noise “uproar, brawl” and from Latin word nausea, meaning“disgust, annoyance, discomfort,” and in some cases, literally “seasickness”. Used in Software development since late 1980’s.
