Rasmussen Redux: The Accimap Revolution

Accidents are not caused at one level. Neither are solutions.

This presentation dives into Accimaps as a practical way of analysing complex incidents across organisational, technical and regulatory layers. Instead of blaming individuals, Accimaps make causal relationships visible—from policy decisions to frontline work.

Engineers will recognise the value immediately:
this is systems thinking turned into a usable analytical tool.

The session shows why Accimaps are now widely used in sectors like healthcare, rail and energy—and why they remain one of Rasmussen’s most influential legacies.

If you want to understand how multiple small decisions align into system‑level failure, this talk is essential viewing.
