In the later model of the domino theory, what was added to account for managerial issues?

• A. Managerial influence and managerial error dominoes
• B. Human factors
• C. Equipment failures
• D. Communication failures

Answer: (A)

The concept being tested is that accidents develop through a chain of events, and the later version of the domino theory explicitly adds management as a factor in that chain. In this revised model, two additional dominoes—managerial influence and managerial error—were introduced to show that what managers decide and how they lead, supervise, and allocate resources can either interrupt or propagate the sequence toward an injury. This shifts the focus from only worker actions and technical failures to the safety system as a whole, emphasizing leadership, policies, training, and organizational culture as critical controls that can prevent accidents. Understanding this helps you see why management matters: strong safety policies, proper supervision, effective training, and a culture that prioritizes safety can stop the domino effect before it reaches the worker, whereas poor management decisions or neglect can contribute to the chain. The other options refer to factors that contribute to accidents, but they don’t capture the specific added element of managerial influence and error that the later model introduces.
