Why can’t you “move fast and break things” in a factory? Because a small software bug doesn’t just crash an app, it can shut down a plant the size of a small city. David and Willem explain the hidden world of operational technology, where safety always comes before speed.

In this episode, David Ariens and Willem van Lammeren, co-authors of “The IT/OT Handbook” and hosts of the IT/OT Insider podcast, break down the divide between IT and OT, information technology and operational technology, and why closing it matters more than ever as manufacturing digitalizes. They explain why OT prioritizes safety and integrity over confidentiality and share a war story where a single form change in China left hundreds of trucks stranded outside a factory. David and Willem walk through the seven cooperation patterns from their book, from “good shadow IT” to facilitation, project teams, and full product teams, and explain why breaking down silos too early can backfire. They also discuss why factories still run Windows XP decades past the end of life, why generative AI’s impact on manufacturing will be slower and different from software, and why the real shortage in this industry isn’t AI, it’s automation engineers.
