Consider the Failure Scenarios

The cable snapped, and a 25-tonne undersea mining vehicle is now stuck at the bottom of the Pacific Ocean.

Having one cable is the proverbial “single point of failure.” Just like in IT, it might not make business sense to pay the extra cost for full redundance. But in a professional IT organization, somebody has examined the failure scenarios. If the database server crashes, we might lose this much data, and we will restore operations in this way.

Sending a robot to the bottom of the ocean without implementing a feature that allows it to autonomously return to the surface seems like an over-optimistic strategy. Do you allow similar unwarranted optimism in your IT organization?
