Position checklists at boundaries between preparation and execution, where the cost of catching errors is lowest and the cost of missing them is highest.
Why This Is a Principle
This principle derives from Exponential Information Decay (memory decay) and Catastrophic failures in complex systems rarely result… (failures result from alignment of multiple failures). It prescribes the optimal temporal placement for checks: at the boundary where errors can still be corrected cheaply before they propagate through the system.
