Field guide 01 / Systems engineering

Systems Engineering Foundations

Learn to see relationships, define boundaries, manage interfaces, and connect engineering evidence—one illustrated lesson at a time.

Reading order

Start with the whole. Then add complexity.

Each lesson stands alone, but the sequence builds a useful vocabulary before adding new kinds of complexity.

The course

12 illustrated lessons

01

Systems Thinking

Move beyond isolated events to understand boundaries, accumulation, feedback, delay, and emergence.

42 min · Foundations
02

Modular Design Systems

Decompose systems around responsibility, hidden decisions, and explicit interface contracts.

48 min · Foundations
03

Model-Based Systems Engineering

Make a connected model, not a document stack, the primary engineering artifact—SysML, the v2 standards shift, and an honest look at the evidence.

14 min · Foundations
04

Systems of Systems Engineering

When the thing you engineer is made of independently owned systems: Maier's five characteristics, the four types, emergence as the core challenge, and the multi-agent AI parallel.

15 min · Foundations
05

Digital Twins

A live virtual model of a physical system, where twins attach to the Vee, why they need continuous V&V, and what changes when AI is added.

20 min · Digital
06

AI-Enabled Systems Engineering

What happens when an AI agent reads and writes the system model directly—where the MBSE-plus-agent partnership is real today, and where it is still a research proposal.

13 min · Digital
07

Requirements Gathering and Engineering

The requirements hierarchy, what makes a statement well-formed, EARS syntax and its five patterns, an honest look at the CHAOS-report evidence, and how EARS now constrains AI-generated code.

14 min · Definition
08

Systems Architecture

Not the diagrams but the decisions underneath them: viewpoints and views, Kruchten’s 4+1, architecting as a heuristic discipline, and what a weighted trade study actually proves.

13 min · Definition
09

Foundations of Human-Automation Interaction

Part 1 of the Human Systems Integration primer: function allocation and the Fitts list, the evidence that reversed it, ten levels of automation, the four-function model, and the ironies of automation.

13 min · Human Systems Integration
10

Trust, Complacency, and Situation Awareness

Part 2 of the Human Systems Integration primer: Endsley’s three levels, the out-of-the-loop problem, use/misuse/disuse/abuse, calibrated trust, and why training alone does not prevent automation bias.

13 min · Human Systems Integration
11

AI Teammates: What's Actually New

Part 3 of the Human Systems Integration primer: silent model updates, goal delegation instead of function allocation, failures that sound right, and how many agents one person can oversee.

13 min · Human Systems Integration
12

History and Future of Autonomous Systems

A special feature spanning both primers: an interactive timeline from Watt’s governor and cybernetics through Shakey, two AI winters, the DARPA challenges, and the transformer to agentic AI.

Working skills

What you will practice

Frame the system

Draw a useful boundary, identify stakeholders, and trace feedback rather than analyzing isolated parts.

Design for change

Use cohesion, coupling, interfaces, and event-driven communication to make modular tradeoffs explicit.

Connect evidence

Relate needs, requirements, architecture, analysis, and verification through traceability and viewpoints.

Coordinate autonomy

Reason about governance, interoperability, emergence, and cascading risk across independent systems.

Lesson format

Read it. See it. Trace the sources.

  1. LearnBeginner-focused explanations use cited standards, handbooks, and foundational literature.
  2. SeeOriginal technical line-art diagrams make each concept and relationship visible.
  3. VerifyEvery claim carries an in-text citation, with full APA references per lesson.
  4. KeepEach lesson prints to a clean, ink-friendly PDF for offline study.
