Question-first modeling
We rehearse the business question aloud before touching relationships so your star schema stays tied to decisions, not convenience.
Quiet metrics we watch between cohorts
6 seasons iterating the same syllabus spine
1,420 async submissions mentor-marked
9.1 / 10 internal rubric after last studio block
312 mentor studio hours last quarter
18 partner org stickers on the studio wall
Numbers shift by intake; we publish ranges to set expectations, not to imply ranking against other schools.

Signal path — from question to publishable visuals
Markup, not mystery feedback
Reviewers leave traces you can search later — bookmark states, DAX diffs, and short Loom-style notes on your visuals.
Publish packets that travel
Stakeholder handoff templates cover projector rooms, async PDFs, and embedded tiles without inventing new jargon each week.
Cadence we run with every cohort
Five beats, not a circle diagram — each step has artifacts you can drop into your workspace library.
01 — Anchor
Pick the operational question and success signal before opening Desktop.
02 — Model draft
Sketch grain + relationships with mentor checkpoints mid-week.
03 — Visual pass
Layer visuals with narration scripts tied to bookmark states.
04 — Reviewer sync
Upload package; receive markup within the published turnaround window.
05 — Handoff
Freeze a publishable packet with version hash + stakeholder notes.
Notes from recent Power BI tracks
“Deck Studio’s deep link policy worksheet stopped our executive snapshot pack from drifting every sprint. The Stakeholder Deck Studio dry-run rubric is picky in a way our reviewers appreciate.”
“Semantic Model Clinic bridge table week rewired how I explain many-to-many paths on calls.”
“Row-Level Narratives cohort: dynamic titles finally match how our CS leads scan tiles. Still tightening one tooltip string — mentor pinged me examples within a day.”
“Warehouse to Dataset Lineage poster is pinned outside our ops pod. Incident comms template reads human, not robotic.”
Teams that lent us their acronyms for a season
BI analysts, department leads, and operations crews — mostly Japan-based, some regional hubs — who wanted structured English-language Power BI training without vaporware promises.
