SFEIR article (in French) that formalizes an **AI-driven SDLC in 11 phases (0 to 10)** and argues that the industry is converging toward it. Starting observation: in 2025, organizations added AI tools without transforming their operating model — producing a paradox of « everything changes… and nothing changes » (execution speed multiplies without proportional gain). The real answer is not the choice of tools but the **redesign of the cycle** for machine execution. The SFEIR cycle rests on **three immovable human gates** (Define, Plan, Ship), automatic phases between them, and **two capitalization moments** (Compound-1 pre-deployment, Compound-2 in production) that turn lessons into reusable rules. Three principles: **AI executes** (complete artifacts + proof of execution, never trusting the agent's own claims), the **human retains control of intent**, the **system learns cumulatively**. Measured results (redesign 6 months→1 day, **−30% of iterations** after ten cycles) and claimed convergence with ADLC, Google, and DORA 2025.
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."
