When Experiments Aren't an Option


Whenever I go to a new restaurant, for the first few visits I’ll order a different meal every time. Sure, one of them might turn out to be a disaster, but the cost of failure is low and it’s the easiest way to determine which menu items I like the most.

This same experimental approach works very well for most of the decisions we encounter every day in our lives and in our work.

But what about the big decisions that land on executives’ desks, where the cost of failure is high and there’s no room to simply try again? For example, decisions around NASA’s next space mission, where a wrong choice could cost millions and endanger the lives of the crew.

Experiments are no longer an option. But this is where digital twins can help.

Digital twins are “digital representations of physical systems that are updated with data from the real world.” They were originally only available to the largest and best-funded organisations, such as NASA, but recent technological advances have changed that, making them a tool that data scientists in all organisations should now consider.

In the latest episode of Value Driven Data Science, Dr Greg Biegel, author of Digital Twins in Action, joins me to explore what digital twins actually are, how they enable better executive decision-making and what data scientists need to know to start working with them.

You’ll discover:

  1. What a digital twin actually is and what distinguishes it from a traditional simulation [02:35]
  2. The five capability levels of digital twins explained through Google Maps [09:12]
  3. How digital twins transform raw operational data into executive decisions [14:07]
  4. Why you should always start from a decision and not a technology [25:20]

When experiments aren’t an option, better models of the world are. This episode will show you what that looks like.

We all know the story of Orson Welles' infamous radio broadcast of The War of the Worlds. On Halloween Eve in 1938, Welles dramatised H.G. Wells' novel about an alien invasion so convincingly that listeners genuinely believed the world was being attacked. The result was widespread panic across the US, with people taking to the streets in fear. It's the most famous radio hoax ever, and from the 21st century it can seem pretty hard to believe. And yet we believe it because that's what the...

One of the most frustrating things about working with AI is when you get to the point where it seems like Claude or ChatGPT or your AI tool of choice really understands you and the way you work - and then all of a sudden it doesn’t. It’s like training a new graduate to be useful at their job, only to be told they’ve moved to another role and you have to start again, training someone else. This is annoying enough when dealing with AI chatbots. But, when building AI systems, it can be...

Earlier this month, Anthropic launched the Claude Frontier Academy, a program designed to train engineers to change how businesses run using agentic AI. The announcement reads as a clear signal that AI models alone aren't enough to create business value and that people are still essential for this technology to succeed. I couldn't agree more. The program's target profile makes this point even clearer. Anthropic wants engineers with strong technical skills, but also "experience helping others...
