Book excerpt: The organisational chart that no longer fits and how to develop talent in the era of AI

Abstract

As artificial intelligence (AI) agents assume the information-routing functions that have defined organisational hierarchy since the Roman Army, the traditional organisational chart is giving way to a new form: an hourglass. In this emerging structure, a broad base of agents handles execution, a concentrated top layer of humans exercises judgment over strategy, ethics, accountability, and relationships, and a thinner, transformed middle focuses less on coordination and more on governance, culture, and capability building. This paper argues that most organisations are currently running redundant human and agent coordination layers in parallel, rather than redesigning around the new reality. It shows why automating entry-level analytical work threatens the traditional expertise pipeline through which junior employees developed judgment via repetition, feedback, and tacit learning. The paper proposes two remedies: reverse apprenticeship, in which juniors review agent output under senior guidance; and simulated experience, in which AI generates high-volume, realistic practice scenarios. Drawing on three emerging organisational models, the paper explains how companies can redesign management layers while deliberately preserving the cultural transmission and talent development functions that middle management historically performed.
