Simon Johnson, Esther Renfrew and Maddy Beckett from ORX discuss the value of the three lines of defence (3LOD) model in operational risk management. This follows the publication of the ORX Practice Benchmark on enhancing the 3LOD model, released earlier this year.   They explore what the 3LOD is meant to achieve and it's benefits. They also discuss how our benchmark study shows it's working in practice, what challenges organisations face when implementing it and how views of the model differ across the three lines.   Our members can access the Practice Benchmark for free on our website, and non-members can purchase a copy: https://managingrisktogether.orx.org/research/three-lines-defence-practice-benchmark
