Teach your Students Why Business Plans Fail
What if you kicked off your next semester with a flurry of activity that showed your students how to avoid the biggest mistake in entrepreneurship – by letting them experience it?
This exercise will turn your students’ love for competition into an active learning opportunity about entrepreneurship that they’ll remember for the rest of their lives.
The Marshmallow Challenge is an 18-minute chaotic construction competition that teaches entrepreneurship students why
Invalidated assumptions hinder all new initiatives.
and are ultimately the downfall of most new companies. They learn a bias towards action, and the power of resilience in the face of a challenge.
Many professors use the Marshmallow Challenge as an ice-breaker, or as a team-building exercise, with great results. But very few use it to teach its most valuable lesson . . .
Several of your students will fail this challenge – and it will be glorious!
The objective of the Marshmallow Challenge is for student teams to build the tallest free-standing structure they can out of uncooked spaghetti, string, tape and a single large marshmallow.
Inevitably, your students will assume the marshmallow they need to place on top of their structure is lighter than it is, and they’ll assume uncooked spaghetti is strong than it is, leading to a pile of broken, edible, dreams.
In this way, your students will get to learn first-hand:
Just like in entrepreneurship, invalidated assumptions lead to failure.
In traditional classes, business students get trained to write comprehensive business plans – not realizing hidden assumptions will ultimately hinder their success.
On the other hand, kindergartners excel at the Marshmallow Challenge because they don’t make plans based on hidden assumptions. The first thing they do is run an experiment, putting a marshmallow on a piece of spaghetti to see what happens. From there they iterate, building the tallest structure possible.
This experimental mindset is what you want your students to embody throughout the rest of your course.
With this exercise, they’ll experience the dangers of hidden assumptions first hand so they’ll be primed to validate their business model assumptions in future lessons:
- Do customers have the problem your students want to solve?
- Will customers pay to solve it?
- Can your students actually solve the problem?
Students Love It
400+ pilot students have done the ExEC version of the Marshmallow Challenge. So far, they’re loving it:
“This activity was not what i was expecting and i took away a lot from it. It taught me to look at a project with no previous assumptions and it make me think like a kindergartener again which made me excited.”- Hannah
“The Marshmallow experiment gave me a real life example of why experimenting is much more beneficial than planning things out.“– Morgan
“Now I know the value of prototyping, also, now I understand the importance of identifying the hidden assumptions which cause many times good ideas to fail.” – Andreina
“After the activity, I understood the importance of adapting to problems and the dangers of assumptions.”– Eric
The fast pace, excitement, and ultimate failure many teams experience during this exercise replicate the typical entrepreneurial experience, and demonstrate many of the pitfalls of traditional business plans:
- Insufficient identification of hidden assumptions (e.g. the marshmallow is much heavier than they realize, the spaghetti is less rigid than they expect, etc.)
- Developing plans based on those hidden/incorrect assumptions
- Investing all their resources (e.g. time, tape, etc.) in a single, large, “launch” attempt vs. iterating on many simpler versions
After the exercise, your students can write up a reflection, incorporating essential principles of entrepreneurship:
- Assumption identification, and assumption validation, are critical to creating successful companies
- Iterations and experimentations are the key to validating their business assumptions

I found some interesting methods of teaching early topics for business studies in this site. Thank you for sharing.
I wish to see more methods for other topics too, such as size of businesses.
