Internal model dependency structures: is there such a thing as best?
Alex Marcuson and Marcus Schofield presented findings from our 2025 market survey on internal model dependency structures to around 100 people at the London Market Actuaries Group.
Alex Marcuson and Marcus Schofield spoke at the London Market Actuaries Group (LMAG) this week about internal model dependency structures, drawing on findings from the market-wide survey Marcuson Consulting carried out in 2025. The talk set out to answer a perennial question: is there such a thing as a best dependency structure, and if so, what might it look like?
Around 100 people joined in person and online, not bad given the tube strike. Thank you to Darshika Agarwal and Cian Creedon for hosting us.
Dependency remains one of the more complex areas of internal modelling, and the discussion reflected that. Structure, validation and communicating results clearly to the business are still live challenges for a lot of teams.
LMAG members will receive a copy of the slides, but if you would like to hear more about our findings, please get in touch.
