Les enseignants ont besoin de moyennes à jour immédiatement après la publication ou modification des notes, sans attendre un batch nocturne. Le système recalcule via Domain Events synchrones : statistiques d'évaluation (min/max/moyenne/médiane), moyennes matières pondérées (normalisation /20), et moyenne générale par élève. Les résultats sont stockés dans des tables dénormalisées avec cache Redis (TTL 5 min). Trois endpoints API exposent les données avec contrôle d'accès par rôle. Une commande console permet le backfill des données historiques au déploiement.

Product Brief Template
This is a flexible guide for the executive product brief — adapt it to serve the product's story. Merge sections, add new ones, reorder as needed. The product determines the structure, not the template.
Sensible Default Structure
# Product Brief: {Product Name}
## Executive Summary
[2-3 paragraph narrative: What is this? What problem does it solve? Why does it matter? Why now?
This should be compelling enough to stand alone — if someone reads only this section, they should understand the vision.]
## The Problem
[What pain exists? Who feels it? How are they coping today? What's the cost of the status quo?
Be specific — real scenarios, real frustrations, real consequences.]
## The Solution
[What are we building? How does it solve the problem?
Focus on the experience and outcome, not the implementation.]
## What Makes This Different
[Key differentiators. Why this approach vs alternatives? What's the unfair advantage?
Be honest — if the moat is execution speed, say so. Don't fabricate technical moats.]
## Who This Serves
[Primary users — vivid but brief. Who are they, what do they need, what does success look like for them?
Secondary users if relevant.]
## Success Criteria
[How do we know this is working? What metrics matter?
Mix of user success signals and business objectives. Be measurable.]
## Scope
[What's in for the first version? What's explicitly out?
Keep this tight — it's a boundary document, not a feature list.]
## Vision
[Where does this go if it succeeds? What does it become in 2-3 years?
Inspiring but grounded.]
Adaptation Guidelines
- For B2B products: Consider adding a "Buyer vs User" section if they're different people
- For platforms/marketplaces: Consider a "Network Effects" or "Ecosystem" section
- For technical products: May need a brief "Technical Approach" section (keep it high-level)
- For regulated industries: Consider a "Compliance & Regulatory" section
- If scope is well-defined: Merge "Scope" and "Vision" into "Roadmap Thinking"
- If the problem is well-known: Shorten "The Problem" and expand "What Makes This Different"
The brief should be 1-2 pages. If it's longer, you're putting in too much detail — that's what the distillate is for.
