DESIGN 
WITH 
PERSONAS 
A LEAN 
APPROACH 
Davide ‘Folletto’ Casali

UX Redirector Advisor
@Folletto
THE PRODUCT/USER 
DISCONNECTION
The product shadow 
DISCONNECTION 1
A business at its core is a 
person helping another person.
To make that help scale 
we added layers: software.
That same software casts 
a shadow hiding the users.
Slowly, naturally, we consider 
the software as the end goal.
Design 
for Functions 
Design 
for Humans
The elastic user 
DISCONNECTION 2

users
“ 
”Alan Cooper 
The best way to successfully accommodate 
a variety of users is to design for specific 
types of individuals with specific needs.
1 
How 
do we keep 
the user in focus? 
2 
How 
do we keep 
the team aligned?
THE PERSONAS 
PERSPECTIVE
“ 
” 
If I’d asked people what they wanted, 
they’d have asked for a faster horse. 
Attributed to 
Henry Ford
ALSO REFERRED AS: 
The “I have no clue” quote

ETC…
Personas
“ 
”Alan Cooper 
Personas provide us with a precise way of 
thinking and communicating about how 
users behave, how they think, what they 
wish to accomplish, and why.
Market 
Segment Personas
Behaviour Goal Why
THE EXTENDED JOURNEY 
THE CONTEXT BEYOND YOUR SERVICE 
Your Service 
Journey
Personas are 
not a deliverable 
(but one of the steps is a deliverable)
Consider personas 
as data synthesis 
(but yeah, personas are models)
Research 
Keep 
Researching 
Personas Use

” Bruno Munari 
To complicate is easy, to simplify is hard. 
To complicate, just add, 
everyone is able to complicate. 
Few are able to simplify.
Thanks.
