Short article (**8 pages**, 4 exhibits) from **McKinsey Technology**, authored by **Jared Moon** (senior partner, London), **Rory Walsh** and **Vito Di Leo** (partners, Dublin and Zurich), with **Adam Thelwall**, published in **May 2026**. The authors report productivity gains of **×3 to ×5** with a **60% reduction** in team size at several companies, and attribute them to redesigning the operating model, not to agent deployment alone. Four levers: (1) the **24-hour sprint**, with a night shift of agents (16h) and a human day shift (8h); (2) automating the **handoffs** between requirements, design and code, which they say account for **70% of tech spend** against 30% for deployment; (3) a **knowledge infrastructure** of domain-specific graphs, queried by an agent « bibliothécaire »; (4) resizing teams and the portfolio. On the graph: *« this should not begin with a grand, top-down ontology effort »*. The team figures are presented as illustrative, drawn from the firm's "experience and observation." Extends McKinsey's November 2025 presentation on agent-driven software delivery ([[harrison-maniar-mckinsey-reshaping-software-delivery-agents-2025-11-23]]).

Methodology article by Antoine HABERT (WEnvision) that formalizes **PROJ-AI**: a lightweight methodological layer so that collective projects become transferable rather than dying with their deliverable. Structuring triad: a **version-controlled git repo** (single source), an **AI agent** (Claude Code, Cursor) that reads the doctrine at every session, and a **markdown doctrine** specifying decision protocols and agent behaviors. Six directory zones (DOCS/, IDEAS/, DR/, OUT/, DOCTRINE/, AGENT/), operational **DPEV** cycle (Decide → Promise → Execute → Verify), Decision Records scored across 7 dimensions, dual interface (business Studio + tech CLI/IDE), five agent directives, and a shared **proj-ai-commons** library that bootstraps a project in 30 minutes vs. 1 week. Metrics across 3 engagements: onboarding **3 weeks → 2 days**, structural decisions tracked **30% → 100%**, architecture doc compilation **6 weeks → continuous**. Central aphorism: ***"The project is not a byproduct of the deliverable. The project IS the deliverable."*** Explicit stance: technology 20%, **team discipline 80%**.
