A mastery-based course for business students enabled by AI

Good Decisions at Any Scale

Welcome! How many bagels should the cafe bake tomorrow? Should the bank approve this loan? Business runs on questions like these, and answering them well means carrying each one across a bridge: out of the real world, into the math world where the reasoning gets done, and back again with an answer someone can act on. Crossing that bridge is a skill, and like every skill worth having, we build it through practice, mastering the simple before moving on to the complex.

That is why this course is built around practice, and its design borrows from the swim classes taught at UD's gym. There, instructors divide the two pools into 22 stations. A swimmer works at one station until she masters its skill, then moves on to the next, all at her own pace. We do the same here: 22 stations across five lanes. You write the code, and you have an AI tutor to ask when you get stuck. You advance the moment you are ready, not when the calendar says so.

Moving at your own pace also means you cannot fall behind. Nothing is averaged, nothing is hidden, and every station can be retried until it clicks. So if math or code has ever made you nervous, this design is for you. Each of the five lanes below trains one skill, and each skill builds on the one before it.

1. Lane 1

   Put your work in code. A decision you write as a program keeps working while you sleep. It can run a thousand times a day, and it never gets tired or forgets a step. But a program will repeat a bad decision just as tirelessly as a good one. So first get the tools running, then learn what makes a decision good.

2. Lane 2

   Reason under uncertainty. What makes a decision good? Not the outcome. You have to choose before you know how things will turn out. Probability is the set of rules for choosing well anyway.

3. Lane 3

   Simulate what you can't work out by hand. Real problems have too many moving parts to reason through step by step. So let the computer play out thousands of possible futures and watch how each choice tends to end.

4. Lane 4

   Draw what causes what. A simulation is only as good as the story behind it. Causal diagrams make you draw that story, so your assumptions are out in the open and the data cannot quietly mislead you.

5. Lane 5

   Make it land. A sound analysis changes nothing until someone acts on it. Visualization turns your reasoning into something a busy decision-maker can see, believe, and act on.

Put all five together and no decision is out of reach. It can affect one person or millions, happen once or repeat automatically all day long. That is what it means to make good decisions at any scale.

Here is how mastery works. At each station, you pass a timed skill test with numbers generated for you alone. Each lane ends with you deploying a live, automated decision-maker to your own website. Your ladder points come from the highest lane you complete.
