5. DEVELOPMENT METHODOLOGIES
DEVELOPMENT TECHNOLOGIES
Many software development projects fail to
achieve their goals. Some estimates of the
failure rate put it as high as 60%.
Much of this problem can be traced to poor 5 /35
communication between developers*
USER INTERACTION DESIGN
and their business clients* or between
developers and their users*.

9. DEVELOPMENT METHODOLOGIES
understanding the business
DEVELOPMENT TECHNOLOGIES
Successful developers work carefully to
understand the business’ needs and
refine their skills in collecting
requirements from non-technical
business managers. 9 /35
USER INTERACTION DESIGN
Since business managers may lack the
knowledge to understand technical
proposal, dialog is necessary to reduce
confusion about the implications of
design decisions.

10. DEVELOPMENT METHODOLOGIES
user-centered design
DEVELOPMENT TECHNOLOGIES
Successful developers also know that
consistently following user-centered
methodologies* can help design teams
meet budgets* and schedules* for the
development of a product*. 10/35

18. ESTABLISHED METHODOLOGIES
DEVELOPMENT TECHNOLOGIES
There are dozens of advertised
methodologies – from software
engineering to business oriented
approaches – but we’ll focus on the well-
tested and widely used method, 18/35
The Logical User-Centered Interactive
USER INTERACTION DESIGN
Design Methodology (LUCID).
It identifies six stages:

We’ll create personas* for this stage of 28/35
development of your interactive
USER INTERACTION DESIGN
product.

29. PERSONAS
model of a user | 角色
DEVELOPMENT TECHNOLOGIES
A persona is a model of a user that
focuses on the individual’s goals when
using an artifact.
角色指的是一个虚拟的人物模型，他代 29/35

身上。

31. PERSONAS
purposes and people
DEVELOPMENT TECHNOLOGIES
Personas also focus on the motives
behind the user’s actions. Cooper
(1999, p.149) argues that good
interaction design has a meaning
only in the context of a person 31/35
actually using it for some purpose:
USER INTERACTION DESIGN
“You cannot have purposes without
people […] That is why the two key
elements of our design process are
goals and personas; purposes and
people.”

32. ACTIVITY #3
personas
DEVELOPMENT TECHNOLOGIES
Create 3 (three) personas for your
interactive product, according to
the template handed in class;
Each persona must include: 32/35
-Name;
USER INTERACTION DESIGN
-Personal Profile;
-Background;
-Attributes;
-Customer needs.

33. HOMEWORK [ GROUPS ]

-- at least -- 3 (three) personas
for their proposed interactive product
according to the template presented in
class. 33/35
