Designs that cross team boundaries
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
explain why a design spanning several teams fails for different reasons than a single-team design.
Planned topics
- Inside one team, a design is decided by people who share context; across teams, each team has its own priorities, roadmap, and vocabulary.
- Most failures are at the seams: unclear owner, mismatched assumptions about an interface, or a date nobody committed to.
- The lead's job is alignment before decisions harden, not drawing the best diagram alone.
- A design is "done" when every affected team can say what they build, what they depend on, and by when.
Draft outline details
Demonstration
A one-line seam list for the FulfillCo program: stock updates (warehouse to shop), shipment status (warehouse to shop), returns (shop to warehouse), identity (both). Next to each, the question "who owns this and who consumes it?"
