Scenario

18.Thetableeveryonedependson

A subscription business has one table everybody quotes: daily monthly-recurring-revenue. You own it. Twelve other teams build on it — board reporting, the investor pack, sales commission, the churn model, and eight more — and their pipelines start when yours finishes. Design the pipeline, and design what you owe them.

This pipeline must answer

01Twelve teams read this table. Can you list them without asking around?
02You need to remove a column. How does that reach them before it breaks them?
03The run is two hours late. Whose morning have you just ruined?

Guardrails

Consumers schedule against your completion time
You must be able to change the table without breaking twelve teams
A missed run is their incident too
Include a check before anything downstream reads it, and a failure path
Avoid invalid cycles

Act 1 · Specify — answer all 8 and your spec flows0 / 8 answered

1Trigger & cadence

Downstream pipelines start when yours finishes. What runs, and when?

The cadence — and the fact that it is now somebody else's dependency rather than your preference.

This choice changes which questions you are asked next — and the pipeline you end up drawing.

◆ What you are committing to on the canvas

What time have you actually promised, and to whom?
e.g.
If nobody wrote it down, twelve teams have each guessed, and they have all guessed differently.
- configTrigger `Runs` = daily / hourly — leaving it unset is what fails the freshness check
What happens downstream if you move it by an hour?
e.g.
Their schedules are keyed off yours. Moving your run is a change to their pipelines that you make on their behalf without asking.
- nodeOrchestration & contracts → Scheduler trigger for a clock; Amazon MWAA, Step Functions, Dagster or Prefect when one step has to wait for another to finish

Design review

The reviewer reads your pipeline.

Run the review to check your architecture against this scenario — a valid DAG, a trigger for the freshness SLA, a transform stage, a quality gate before publish, and a failure path — then defend it in a short interview.
