How Dare You Make My Team Lose?!

Building a data science model for an academic paper is one thing. Building a model that has to work perfectly during the Cricket World Cup with millions watching is something else entirely. There’s no room for the kind of errors that might be acceptable in research settings or even standard business applications. And if you get it wrong, you get emails… Lots of emails… From people all around the world… The type of emails that begin with: “how dare you you make my team lose?!” Worse still? You only get one chance. As Prof. Steve Stern, official custodian of the Duckworth-Lewis-Stern (DLS) cricket scoring system puts it: “If you create a catastrophe, that’s it. You won’t be asked back to the table.” In the latest Value Boost episode of Value Driven Data Science, Steve joins me again to share practical lessons from deploying the DLS method in high-pressure, real-time environments where mistakes have global consequences. In just 12 minutes, you’ll learn:
You can’t eliminate all risk when deploying high-stakes models - but you can control it with the right approach. Listen now on Apple Podcasts or Spotify, or click the link below: Episode 95: Building Models That Work While Millions Are Watching Talk again soon, Dr Genevieve Hayes |
Data Science Impact Algorithm

Around age 19, having just graduated high school, I got my first job in "data". I could barely use Excel and thought Python was something you'd find at the zoo, but a friend of the family hired me to tutor their teenaged son. My maths was good enough to help him get through high school maths. Around age 29, having just finished my PhD, I landed a role managing an insurance pricing and analytics team. I'd never heard the term "machine learning" back then, but I had spent a good chunk of the...
You’re already using optimisation every day as a data scientist - but you probably don’t think about it. Every time you train a machine learning model, you’re running an optimisation algorithm to find the best parameters. But there’s a second type of optimisation that most data scientists never even touch - and it’s where the real business value often lives. It’s called decision optimisation, and it can transform your ML predictions into actionable decisions. Here’s the difference: ML...
Data science exists to support decision making, but within any organisation, there is a hierarchy of decisions - low stakes, high volume decisions at the bottom; high stakes, low volume decisions at the top. Executives care most about the decisions at the top. There’s valuable work at the bottom of that hierarchy. But automating routine decisions is about clearing the path so executives can focus on the high-stakes decisions. It’s not about walking it with them. For years, data science has...
