L'IA fait tomber les murs entre les métiers
In-depth op-ed published on **sfeir.com** on August 1, 2026, authored by **SFEIR** (the firm's editorial voice). It brings together **two July 2026 publications** with opposite methodologies — the preregistered field experiment **"The Cybernetic Teammate"** at **Procter & Gamble** (Dell'Acqua, Ayoubi, Lifshitz, Sadun, **Ethan Mollick** et al., *Organization Science* 37(4), 2026) and the first report in **OpenAI Economic Research**'s **"Work at the Frontier"** series (Jul. 27, 2026, >800,000 messages from US ChatGPT users) — into a single thesis: *"generative AI doesn't just speed up existing work, it redistributes who does what."* The architecture unfolds in four stages: **the mechanism** (P&G: AI acts as a *boundary-spanning* device, erasing functional silos — an individual + AI reaches the level of a pair without AI, **+0.37 σ**), **the scale** (OpenAI: **43.5%** of profession-specific messages fall outside the user's own profession), **the agenda** (Mollick: the walls are thinning, the division of labor must be rethought, and well-orchestrated recomposition "pays off handsomely"), then **the firm's response** — **Skill Based Organisation (SBO)**, adopted at SFEIR under the impetus of **Rosalie Zandona** (VP People & Culture): **actually operational skill** replaces the job description as the unit of organization (**up to 13 skills identified per role**), shifting from a **status-based identity** ("I am a manager") to an **operational identity** ("I know how to design complex architectures"). The rhetorical move is proof by internal example: *"we made the shift in-house before recommending it."* **Three caveats are noted**: the SBO shift dates back to **February 2026**, hence *predating* the diagnosis it is supposed to resolve (the argumentative order reverses the chronological order); **nothing in the data demonstrates** that a skill-based organization absorbs crossover better than a role-based one (an untested design hypothesis); the P&G result has been circulating **since March 2025** (NBER w33641) — the "a few weeks earlier" applies to the peer-reviewed publication, not to the result itself.
