There once was a monastery in perched high on a cliff several hundred feet in the air. The only way to reach the monastery was to be suspended in a basket which was pulled to the top by several monks who pulled and tugged with all their strength. Obviously the ride up the steep cliff in that basket was terrifying. One tourist got exceedingly nervous about half-way up as he noticed that the rope by which he was suspended was old and frayed.
With a trembling voice he asked the monk who was riding with him in the basket how often they changed the rope. The monk thought for a moment and answered brusquely, “Whenever it breaks.”
Being scared of heights, I’m not sure I would get in that basket, even if the rope was brand new and 6 inches thick. No-one in their right mind would get into that basket if there was visible wear and tear on the rope. It would be a good idea to inspect the rope regularly and replace it at the first sign of damage. For the really paranoid, you might even replace it every so often with a new rope just in case.
But when it comes to the world of software, it’s a little bit different. People are very risk averse. Even if the software they are running has a known serious defect, they sometimes perceive the risk of taking a fix to be higher than living with the status quo. So let me get this straight, in software terms, you are dangling in a basket hundreds of feet up suspended by a dangerously frayed rope. I’m offering to fit you a new rope, but you don’t want to take it in case there’s a manufacturing defect. Or maybe it might cause a problem with the basket. Why did you even report the problem if you don’t want to take a fix?
It’s not a fair analogy because software is much more complex than a simple basket suspended by a rope. There are many interdependencies. But even so, the risk of doing something always needs to be compared with the risk of doing nothing. Yes, something might go wrong, but you are in a situation where something is absolutely definitely wrong right now and causing you lots of pain.
