CORE DEFINITION

Literally meaning "big room." All project-related information (charts, schedules, issue lists) is physically posted on the walls of a room, and all decision-makers regularly meet in this room "facing the walls." Scaffolding effect: information transparency. Breaking down departmental silos. When all information is displayed on the walls without obstruction, no one can claim "I didn't know" or "I didn't receive the email."
