Nadia's Q3 Revenue by Region — Chapter 7 Worked Example ============================================================= The regional-revenue dataset behind Nadia's hand-built vs Copilot-first-draft comparison in Chapter 7 of The Defensible Decision. One quarter, four regions, $28.4M on plan — and one region hiding a material miss. Wholly synthetic. Any resemblance to a specific real enterprise cloud-revenue quarterly report is coincidental; the numbers are constructed to make the on-plan-hides-miss pattern visible. Files ----- - nadia-q3-region.csv — flat rows: one quarter total + four regional rows - nadia-q3-region.json — canonical scenario contract with source hash What it represents ------------------ The Q3 revenue-by-region snapshot from a CFO reporting cycle. The aggregate quarter number ($28.4M) lands exactly on plan; the regional split shows NA -5.3% behind plan while APAC, EMEA, and LATAM all beat theirs. Chapter 7 uses the dataset to contrast a Copilot-generated first-draft bar chart (alphabetical sort, no plan reference, descriptive title) with the hand-built chart Nadia has produced quarterly for two years (variance-ascending sort, plan-reference ticks, single accent on the region that missed, Big-Idea title). Invariants (locked) ------------------- The scenario carries executable invariants that Chapter 7's release contract enforces: - Quarter total revenue: $28.4M, exactly matching quarter plan ($28.4M). - Exactly four regions: APAC, EMEA, LATAM, NA (alphabetical in the source; the hand-built chart re-sorts). - Regional revenue sums to the quarter total exactly (4.9 + 8.3 + 2.6 + 12.6 = 28.4). - Regional plan sums to the quarter plan exactly (4.7 + 7.9 + 2.5 + 13.3 = 28.4). - NA is the only region below plan (12.6 vs 13.3 = -5.3%); the other three beat plan (+4.3%, +5.1%, +4.0%). - The AI first-draft state uses alphabetical sort with no comparison encoding. - The hand-built state sorts by plan-variance ascending with per-region plan reference ticks and a single accent on the NA bar. Why the invariants matter ------------------------- Chapter 7's pedagogical point is the difference between a chart that shows the numbers and a chart that shows the argument. If NA's miss weren't material, or if any other region also missed plan, the contrast Fig 7.4 draws (CFO sees the miss on the hand-built side; CFO does not see the miss on the AI-draft side) would soften into ambiguity. The single-region-miss-inside-an-on-plan-quarter shape is the exact scenario the five-principle rubric was built to catch, so the numbers are locked to keep that scenario stable. What it does NOT represent -------------------------- - Actual enterprise cloud-revenue data from any real company. - Nadia's Q4 forecast (the chapter's arc closes at the Wednesday-morning review; Q4 is left to the reader's discipline). - The five-principle rubric scoring for Fig 7.3 (that lives in the chapter prose; the dataset only carries the numbers behind both chart states). Reproducibility --------------- The dataset ships from the book source at AlexBooks/applied-ai/ai-directed-viz/data/nadia-q3-region.json and is re-emitted here by AlexBooks/applied-ai/ai-directed-viz/scripts/generate-nadia-region.mjs --site-root . The generator writes the source SHA-256 into nadia-q3-region.json so drift between the book and this site is detectable. License ------- Released for teaching use alongside The Defensible Decision.
