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