It rarely begins with a collapse. It begins with an explanation.
The customer delay had a reason. The missed handoff had a reason. The budget overrun had a reason. The late update had a reason. Each explanation sounds reasonable by itself. Each adjustment feels temporary. Each recovery feels manageable. For a while, leadership learns to live with the pattern because the explanations are not false.
That is the danger. Not that the explanation is wrong, but that the explanation becomes sufficient.
