3. One Size Fits All
“… the human interface of
some software applications
gives the impression that
the designer’s model of the
user was a 25-year-old
male with a doctorate in
computer science who is
besotted with technology
and is more interested in
playing with a computer
than in completing useful
job of work!”

9. Persona with Important Personal
Factors Listed
• Rose is an 83 year old great
grandmother. Although fiercely
independent, she struggles with
everyday tasks like shopping,
cooking and housework. Carol
and David need to come round
most days to help.
• She still greatly enjoys an active
social life - including her regular
bridge and quiz night every week
and going out for meals with the
whole family.
• Unlike David, Rose has come to
accept her hearing aid as a
necessity. She has worn reading
glasses for many years and
always carries them with her.
