11. Personas
are fictional characters created to represent
the different user types within a targeted
demographic, attitude and/or behaviour set
that might use a site, brand or product in a
similar way.

12. Personas
A persona is a kind of an imaginary person with
a name, history, and story who has a way of
doing things.

13. Personas
A persona should have enough psychological
detail to allow you to conveniently step over to
the persona’s view and see your products and
services from her perspective.

14. Personas
A persona can function almost like another
person in the room when making a decision—It is
“Magnus.” He looks at what you’re doing from
his particular and very specific vantage point,
and points out flaws and benefits for him.

15. about potential customers
Describe a stereotypical customer
as detailed as possible
Facts & demographics
• Name, Gender, Age, Education, Occupation…
Behaviours
• What books does he/she read? What's he/she
already doing to solve the problem you want to
solve for him/her?
Problem & needs
• What are her points of pain as HE/SHE thinks
about them? What product or service, similar to
yours, is he/she using but unsatisfied with? Then,
what problem is he/she trying to solve with that?
What challenges keeps him/her up at night trying
to google the answer?
Goals & dreams
• What is he/she trying to accomplish? What is
most important to him/her?
icon by Paulo Sá Ferreira

16. about potential customers
Places
• Where (online and offline) can you find him/her?
Forums? Comment sections of which blogs?
Social networks? Meetups? LinkedIn, Facebook,
Google Groups?
Key influencers
• Who does he/she trust as a thought leader? Who
knows a lot of your customers and can introduce
you to them?

’If I had asked people what they wanted, they
would have said faster horses.’

28. Anybody will say your idea is great
if you annoy them for long enough.

29. A man wakes up, turns on the
radio, goes upstairs, turns on the
lights, and kills himself.

31. #1 Use a script or survey
Three ways to horrible screw up
customer development

32. Always know your big 3
questions
Don’t stress to much about choosing the “right” important
questions. They will change. Just choose the 3 questions which
seem murkiest or most important right now. Doing so will give
you a firmer footing and a better sense of direction for your
next 3.
Knowing your list allows you to take better advantage of
serendipitous encounters.

33. Questions to dig into feature requests
# Why do you want that?
# What would that let you do?
# How are you coping without it?
#Do you think we should push back the launch date, add that
feature, or is it something we can add later?
# How would that fit into your day?

34. Questions to dig into emotional signals
# Tell me more about that.
# That seems to really bug you - I bet there’s a story here.
# What makes it so awful?
# Why haven’t you been able to fix this already?
# You seem pretty excited about that - it’s a big deal?
# Why so happy?
# Go on.

35. Softball and anchor questions
How’s it going with..?
Interesting: tell me more about that..
Can we go back to what you were saying about..?

Progress Report Board team:
First validate that your
customer has a problem
Then, state what your assumption
is of the ideal soluotion, and build your
experiments to validate those assumptions
Fill in your persona sheets and
refer to those, you can give them
names to match their personality
Of all the assumptions you have,
state the one, which if proved wrong,
will invalidate the whole business
Design an experiment which will
(in)validate the riskiest assumption
most efficiently
Call the criteria the results need to
meet for the assumption to
be validated
State the results of the experiment
compared to the criteria, and thus if
it’s validated or invalidated, and if
you’re going to pivot, iterate or
persevere
Inform us on the problems your
customer or persona is having and
how severe those pains are
according to you
