# Ranking risks on an assumption map

Lesson 16 of 43 in **Start your own business** (ENTR 242), unit "Business models and riskiest assumptions". An open lesson from Maestro College.

## What the learner will be able to do
- Identify at least six assumptions across a business model and label each as a desirability, feasibility or viability risk.
- Rank the assumptions on an assumption map by importance and existing evidence, and choose the riskiest one to test first.

## Teaching notes
Scenario: FixFlow, an app that lets small landlords (1-10 rental units) receive, track and assign tenant maintenance requests, aimed at self-managing landlords with 3-10 units and a planned $5 per unit per month subscription. Learners pull assumptions from its Lean Canvas and Value Proposition Canvas onto the map; create an illustration that shows the assumption-map grid of importance versus evidence.

## Course teaching approach
- Start from a real-world problem, then introduce the concept as the solution.
- Keep it true beginner level, hands-on, a little gamified. The learner should feel they are winning.
- Balance explanation, demonstration and practice. No copy-paste exercises: give small story-based tasks.
- End with one fun closed question about the topic.

## How to use this document
You are acting as a tutor for a learner on Maestro Open. Teach from this document, one small step at a time. Ask the learner to try things, wait for their answer, then give feedback. Keep it beginner-friendly. If the lesson involves code or spreadsheets and you cannot run them, ask the learner to try it on their own computer and paste the result back. Do not award grades, credit or certificates.

## When the lesson is done
The lesson is complete only when the learner has shown they can do every outcome listed above. Check each one with a small task or question; if an answer is wrong, explain and let them try again before moving on.
When every outcome is covered:
1. Say clearly: "Lesson 16 complete: Ranking risks on an assumption map."
2. Give a two-line recap of what they learned.
3. Name the next lesson, "Writing falsifiable hypotheses for top risks" (lesson 17 of 43), and give the learner its link: https://open.maestrocollege.edu/start-your-own-business/writing-falsifiable-hypotheses-for-top-risks.md. Tell them to paste that page into this chat, or fetch it yourself if you can open links, then start it the same way. Do not start teaching the next lesson's topic until the learner has it.
