Capstone 01
Recreate Harbor Coffee.
Sort what matters, build a model, inspect the evidence, and revise when Sam adds an exception.
Open the coffee capstonePractical systems modeling
Good systems begin with better questions.
A guided workshop in seeing things, naming relationships, and testing the story behind a system.
It is engineering. You can follow the reasoning.
Learn how a conversation becomes a useful model—and how to question that model before it becomes a system. This is for our team, people learning to design systems, and customers who want to understand our process.
One realistic, fictional coffee shop carries the story. A bike shop offers transfer reminders. Then a food pantry asks you to apply the method in a different setting.
The working loop
Listen→Model→Inspect
Question→Learn→Revise
Keep the purpose, story, sources, and uncertainties beside the diagram.
Fixed teaching evidence and scripted AI illustrations. No live AI is needed.
The guided path
One whiteboard, ten visits.
Room 1
You already do this
How do orders reach customers, and where does the wait occur?
Room 2From one thing to a kind of thing
Which distinctions help us describe Maria’s purchase?
Room 3Name the connections
What happened when Maria placed Order #9821?
Room 4A pattern starts a question
Which parts of a familiar pattern fit this shop?
Room 5Change the level of detail
How much detail does the waiting question need?
Room 6One person, roles in context
Who was Maria in this purchase?
Room 7Let the records challenge the story
What should we investigate before changing staffing?
Room 8A different question changes the model
What becomes relevant when Sam asks about muffin stock?
Room 9Keep the revision and its reason
What does “ready” mean when an order has partial handoffs?
Room 10Make the engineering traceable
How does a modeling choice change what a system can explain?
Capstone 02
Carry it into Maple Pantry.
Count people and activities without losing someone’s second role or inventing one they never performed.
Open the food-pantry capstoneRead the reasoning first.
Visit the observation room, the revision room, and the model-to-work review. Every room includes a worked explanation. Reading is exploration; capstone completion requires your own evidence-linked revision.
