1 Identify your users and their characteristics
“Know thy user, and you are not thy user”
– Arnie Lundd



2
Identify your usability requirements

Ask yourself:
What will be measured ?
How it will be measured ?
What level of the measure is required ?



3
Record and analyzing your users’ tasks
“In the future everyone will be famous for 15
In
minutes” – Andy Warhol



4
Understanding your users’ mental models
“All our id
ideas and concepts are only i t
d t l internal pictures”
l i t ”
- Ludwig Boltzmann



4 This raises a number of issues for design:
•What mental model might you expect the user to have?
g y p
•What mental model should they have?
•How should you convey an appropriate mental model to the
user (which may have implications for training)?
•How should you design the interface to reflect the mental
model?
•How do you represent the mental model?



4
And Finally …
The model must be discussed with representative end
users to ensure that it really does correspond to their
understanding



5 Identify appropriate styles and guidelines
d f l d d l
Before you start to create the user interface, you should create project specific
g
guidelines for the task. You may have to tailor the user interface g
y guidelines, to
cover the areas that are relevant for the type of user interface you will develop.

When knowledge is captured in the form of a guideline, it s known as a
it’s
prescriptive theory. Prescriptive theories suggest actions to take that will lead to
desired results. Guidelines aren’t rules to be enforced. They don’t eliminate
creativity and innovation from the design process Instead guidelines are a vital
process.
part of our decision strategy during the design process



6 Design the interface
“A picture is worth a thousand words. An
p
interface is worth a thousand pictures.” – Ben
Shneiderman



7 Prototype the interaction and interface
“God created a number of possibilities in case
some of his prototypes failed ... that is the
meaning of evolution.” – Graham Greene



8 Evaluate and reiterate:
Determine the goals.
g
Explore the questions.
Choose the evaluation approach and methods.
Identify the practical issues.
Decide how to deal with the ethical issues.
Evaluate, analyze, interpret and present the data.



But not necessarily in
that sequence!
It s
It’s an iterative
process…
