Description
Seminar rooms stay small so every table can redraw a real platform map. You bring anonymized diagrams; mentors annotate with queue touchpoints, cache invalidation seams, and read-model ownership. The week closes with a moderated critique using our rubric—not a pass/fail gate, but a shared vocabulary for the next iteration.
What is included
- Rubric-guided reviews with two reviewers per table
- Queue placement exercises on Kafka-compatible flows (conceptual)
- Read vs write model tagging on whiteboards
- Failure-injection stories without naming vendors
- Observability sketch: traces tied to user journeys
- Peer swaps between platform and product squads
- Printed map templates sized for wall discussion
Outcomes
- Produce a defensible service map with explicit async edges
- Prioritize two architectural risks with mitigation sketches
- Facilitate a 45-minute internal review using the rubric

FAQ
Do you share recording-ready slide decks?
We provide printable canvases and rubrics. Decks stay minimal so teams focus on live mapping—not polished decks that age in a week.
Is this only for microservices?
No. Moduliths and hybrid deployments are welcome; the lens is ownership and message flow, not buzzwords.
What is not included?
We do not run production clusters for you, and we do not certify external reviewers—this is practice, not procurement paperwork.
Experience notes
“The rubric forced us to name the async edge we kept hand-waving in the Service Boundary Cartography studio—worth the late nights.”

“Wish we had one more hour on read models, but the printed templates landed in our war room the next day.”
