I want to introduce you to a crazy word. Recrudescence. Sounds like something you'd need a prescription for, right? Or maybe a villain in a sci-fi film. Probably best if you don't use it in general conversation. People might think you're a little weird. Despite the fact that no one ever uses this term, it's actually one of the most important concepts in organisational safety. I somehow managed to tie it onto my latest YouTube video. It means the return of something dangerous that you thought was gone. Not a new failure. An old one. Quietly coming back through the cracks while nobody was watching. In 2024, NASA space junk from a battery pallet, discarded from the ISS back in 2021, crashed through a family's roof in Florida. Imagine that. Having a piece of the space station crash into your lounge room. The formal investigation that followed was pretty slack, considering how big NASA is and how scary the consequences could have been. They produced 4 PowerPoint slides for the formal investigation. Four. Compare that to the post-Challenger report. The post-Columbia report. The depth, the rigour, the organisational honesty those investigations demanded. The scary thing about recrudescence isn't the event. It's the slow, invisible erosion that made the event possible. Skills fade. Standards quietly drop. Nobody decides to do less. It just becomes the norm. Until a piece of space hardware falls through someone's living room ceiling. Have you seen recrudescence happen in your own organisation, even if you didn't have a word for it at the time? Here's my example. I just watched a large company stop using a really awesome piece of programming software that had heaps of functionality, and go back to using Excel spreadsheets. The only reason they stopped using it? The contract was up for renewal, and the software company charged too much. They added one too many zeros, so the company has gone back to the 90's to try to manage a really complex system. It's a set-up for failure. Something is going to be missed.
