How did it make sense?
Podcast Description
'How did it make sense?' explores the local rationality of those involved in doing what they did. Each podcast lasts about 45 mins and aims to follow a similar format. Initially, we will look at the 'first story' which is normally scant in details and triggers an emotional response, and then we will look at the 'second story' that looks at the goal conflicts, the ambiguities, the assumptions, the tensions, and the trade-offs that led to those involved doing what they did. This context-rich story is the one that learning opportunities come from, not focusing on the counterfactuals that often arise from 'first stories'.
The goal is to encourage you to look deeper at the socio-technical system presented by the guests and how we can make improvements by abstracting from the multiple domains discussed in the podcast to the our own domains.

On today’s episode of How did it make sense I am joined by Nathalie Lasselin, a filmmaker, technical diver, explorer, and someone who dives where most people wouldn’t even go looking.
Nathalie’s story starts with an ambitious expedition called Urban Water Odyssey, a 44-mile dive along the St. Lawrence River with a large support team. The plan was meticulous, the team trained, and everything seemed under control, until the dive ran late, the river got busy, and night fell. When Nat surfaced, she was struck by a boat, and only then did the team realise a tugboat was approaching. They pushed her out of the way, but the near-miss revealed a gap in the operation: no dedicated lookout, broken communication, and the kind of task overload that makes obvious risks invisible.
What makes this episode powerful is not just the incident, but the deeper learning behind it. Nat breaks down how the expedition’s delays created cascading failures, how people’s perception of risk changes under pressure, and how the team culture their focus, trust, and ability to respond saved her life. This conversation is a reminder that you can’t design risk out of real-world operations; you can only build resilience and a team that can fail safely.
