Advanced level · Module 1: Designing AI Systems · Lesson 2 of 4
Architecture and Human Oversight
Design the components of an AI system and place human checkpoints where they matter.
In this lesson you will
- Draw an AI system architecture
- Design human-in-the-loop checkpoints

The lesson
An AI system is more than a model: a user interface, retrieval over documents, the model, tools it may call, validation, logging and monitoring.
Place human checkpoints where errors matter most: a case worker approves every referral summary before it is sent; a supervisor reviews flagged cases. The design should make reviewing easy, not a rubber stamp.
Log inputs, retrieved sources, outputs, approvals and edits, so decisions can be audited later — while protecting personal data in those logs.
Step by step
- Draw the capstone system's components.
- Mark human checkpoints.
- Design the review screen.
- Define what is logged and for how long.
Practice activity
Produce the architecture diagram and oversight design for the capstone.
Expected result: A clear diagram with justified checkpoints and logging.
Check your understanding
-
Name four components of an AI system besides the model.
Show answer
For example the interface, retrieval, tools and logging.
-
What makes a human checkpoint effective?
Show answer
Reviews are easy and meaningful, not rubber stamps.
