> if you run your business by relying on people you will be affected by such accidents, if you run your business as if everyone is interchangeable you won't. Even if they are not easily replaceable.

Unless and until the task is trivial and/or very well defined with all constraints, assumptions and risks clarified people are not interchangeable. Paraphrasing Isaac Asimov: [Knowledge Work] does not mean my Ignorance is just as good as your Knowledge.
