Tier meetings are a structured cascade of brief, stand-up daily meetings at increasing organizational levels — T1 at the team/cell, T2 department, T3 plant, T4 site/executive. Each is short, board-driven, and focused on safety, quality, delivery, and abnormalities.
Issues a team cannot resolve escalate upward within hours, while priorities and decisions cascade back down — creating a fast, disciplined operating rhythm built on visual management.
