Text Description is below the image.
  • Tight coupling and high complexity (versus loose coupling and low complexity) are more accident prone.
    • Perrow, 1984, Normal Accidents
  • Also known as "slack", i.e., usual procedures work less well when there is less slack in the system, because the system loses its resilience to additional interruptions.
    • Rudolph and Repenning, 2002
