What you will need

How to proceed
01
Define the
one problem
02
On the
whiteboard
03
Make it with
paper
04
Get real &
test it

You could start by filling out the following
worksheet.
Ask yourself: What is your key target, the
one problem you want to solve? What is
the benefit for your users – and how is it
delivered?
Define the one problem
Step 01

Have a key target in
mind. The one problem
your solution shall
solve. Write it down in a
sentence.

From that, you should
be able to derive the
key benefit, obviously.

Then ask: What does
the solution do to
deliver that benefit?

Now you have two options:
Think the process through in theory,
which you probably have already done,
and define the steps. But here you have a
huge advantage from the prototyping
method: Just don’t do that!
On the whiteboard
Step 02

Just start scribbling the first
step on the whiteboard, even
without knowing what the
second would be.

Imagine this in a real-world
case: What would be the first
(important) thing the solution
should do? That’s where to
start.
(Don’t think about “login”. That’s
something the tech needs you to do
– first focus on what you need.)

And: Scribble. Start with the
frame and the key element
which needs to be seen. And
then add that one interaction
which allows the user to
proceed.

Then jump to the end. Ask:
When will the process end
within my solution? Scribble on
the far right side of the
whiteboard, what you think
should be seen here.

Now, looking back at the first scribble, follow the
“visual” logic to define the next step. What would
be the consequence of that click? That’s what
your next scribble will show. Again, try one key
element and one major interaction.

Stick with the “visual” logic flow. What would the
users see next, what would they want to do. Go
with the must-haves: What’s necessary to reach
the final screen? (You’ll probably have to redo that last
screen in the end – that’s quite normal.)

Redrawing on paper is the first check of
validity: Does everything fit on the screen,
and how does this feel?
Make it with paper
Step 03

Draw it close to the original size.
Close means e.g.,: If you’re
doing an app, your paper screen
might have the doubled size of a
smartphone screen.

The drawings here are of course
the showcase-take-your-time-
and-designer-level …

… normally, they are more
likely to look like this.
And that’s totally ok!

Ask yourself for each screen:
What is the solution’s benefit
we’re showing here? Write it
down. Some steps are just
necessary to continue the
journey with no special benefit
at all. Try to skip as many details
of those as possible – focus on
what brings value to users.

When you’ve done all the
screens, highlight the
interactive parts. If you need
crucial changes on a screen to
happen, use post-its or tape
shreds of paper to fold/unfold.
(Don’t overuse!)
The task is: Make clear how to
proceed.

If you’re not overcrowded yet,
now you have the possibility to
enrich with some secondary
benefits – which might not be
the primary value for your
users, but for those
stakeholders you’ll want to
convince.
Like: Here, they could use special offers of
our partners, or subscribe for updates.

Congrats, you’re done! Now, test it! Show
it to someone who was not involved in
creating the thing.
Get real & test it
Step 04

How to
Let them pretend to use the
solution and speak loudly
what they think while they’re
on it. Do they understand
where to click and what it
does?

How many
3–4 people will find 80% of the
major usability-mishaps,
regardless of how close they
are to the real process, as long
as they understand the one
path through the solution
should do for them.

How to
Redo the screens which failed.
(If you’re unsure, you could
repeat testing with new
participants.)
If you failed hard, throw
everything away and start
completely over.
That’s why we’re doing this:
Rebooting the project will
never be as easy again as at
this moment!
