The purpose of The Global Service
Jam is to promote the discipline of
and to allow interested people to
exchange techniques, ideas and
experience in a relaxed, energetic
You will be guided through the process by the
Jam platform – A web form which guides you
Link yourselves together to form project teams
Make sure to upload mandatory content, as
well as optional.
Don’t wait until Saturday! "Always be
uploading" is very important!
The Upload Deadline is the Deadline to
START uploading your ﬁnal ﬁle.
It doesn't matter if that ﬁle needs
a week to upload,
it must FINISHED before Saturday 8pm!
Uploading 1 video is not enough as it is
usually a presentation, not a prototype!
All teams should upload digitalised tangibles
(tickets, posters, forms), make a wireframe,
draw up a contract, Business Model Canvas,
service blueprint, budget etc.
A video can show the service in use, but we
cannot really interact with it so it's not
really a prototype...!
Instead of video presentations, it would be
much more useful to push the prototype
further and then just present
the prototype to camera.
Avoid the Presentation Trap!!
1. Build the Tallest Freestanding Structure – The winning team is
the one that has the tallest structure measured from the table
top surface to the top of the marshmallow. That means the
structure cannot be suspended from a higher structure, like a
chair, ceiling or chandelier.
2. The Entire Marshmallow Must be on Top
3. Use as Much or as Little of the Kit. You are free to break the
spaghetti, cut up the tape and string to create new structures.
4. The Challenge Lasts 18 minutes. You have to STOP when the
time runs out. Those touching or supporting the structure will
5. Please, ask if you have any questions!
The assumption in the Marshmallow Challenge
is that marshmallows
are light and ﬂuﬀy and easily supported
by the spaghetti sticks.
When you actually try to build the structure,
the marshmallows don’t seem so light.
The lesson in the marshmallow challenge is that we need to
identify the assumptions in our project – the real customer
needs, the cost of the product, the duration of the service –
and test them early and often. That’s the mechanism that
leads to eﬀective innovation.
