In this episode, I discuss the wonderful story of the recent unearthing of the first known organisational chart, the one created by Scottish engineer Daniel McCallum for the New York and Erie Railroad Company in 1855. What is so intriguing is its structure – resembling a plant or a tree, complete with roots (the board) the trunk (main functions) and the branches (specific locations) and even the leaves (specific people). This org chart structure remained the dominant concept for around 70 years until the 1920s when hierarchical (top down) charts started to be created by the forerunner to IBM. Trust scholar and author-turned-creative-design-archeologist Rachel Botsman talks us through how she found this artefact and its resonance and relevance to governance structures today.
