GOMS GOMS
(Goals, Operators, Methods & Selection Rules)
(Goals, Operators, Methods & Selection Rules)
What
An HCI task analysis method that
reduces a user's interaction to its
most basic actions. Operators (steps
that a user performs) combine to
form Methods, which are used to
achieve Goals. Selection Rules
determine the proper Method, when
more than one could be used.
Why
Quantitatively, GOMS gives good
predictions of performance time and
learning. Qualitatively, a GOMS model
is a description of the knowledge
needed to perform a given
task, essentially describing the Used By:
content needed for task-oriented
documentation.

the context and benefits of
use, rather than on specific
interaction details.
Why
Some prototyping methods
concentrate on the granular
details of a design — what Used By:
functions and controls to
include, and how to lay them
out. Because concept videos
tell stories and avoid minutiae,
they are better suited to
explaining a new vision.

Six Thinking Hats Six Thinking Hats
What
A tactic that helps you look at decisions
from a number of different perspectives.
The white hat focuses on data; the red
on emotion; the black on caution; the
yellow on optimism; the green on
creativity; and the blue on process.
Why
Can enable better decisions by
encouraging individuals or teams to
abandon old habits and think in new or
unfamiliar ways. Can provide insight into
the full complexity of a decision, and
highlight issues or opportunities which
might otherwise go unnoticed.

Heuristic Evaluation Heuristic Evaluation
What
A form of usability inspection where
specialists assess how well an
interface complies with recognized
usability principles (heuristics).
Usually two or three experts review a
system, noting and ranking problems.
Why
Provides quick, inexpensive usability
feedback. Can be a good method early
in a development process, as it
concentrates on the basics, ensuring
that an interface is fundamentally
sound before more in-depth testing
with real users.
Resources
Rolf Molich and Jakob Nielsen created
heuristic evaluation in 1990 as part of Used By:
an effort to lower the costs of
usability evaluation. Jakob has quite a
few articles on it; this one is a good
start.

Tangible Futures Tangible Futures
What
Artifacts created to represent the
state of affairs at a future point in
time. Examples might include press
releases, movie posters, newspaper
articles, or product package designs.
Why
Artifacts can be more effective in
communicating future trends than
text-heavy reports. Their concrete
nature may provoke people to think
about what they really believe, and
about how technology interacts with
social, economic, and cultural factors.

Victor Lombardi published a series of
blog posts about this approach
starting in 2006, and continues to Used By:

tangible futures today. The image

Five Whys Five Whys
What
A technique used to probe the root
causes of a problem. Popularized by
Toyota in the 1970s, this strategy
involves looking at any problem and
asking: "Why?" and "What caused this
problem?" The answer to the first
"why" prompts another "why" and
then another, and so on.
Why x 5
It's not uncommon for a project to
focus on the symptoms of a
problem, rather than exposing the
underlying causes. By asking why, and
why, and why again, we gain insight
that allows us to address real
problems in a way that will make a
real difference. Used By:

A study of the actions and cognitive
processes required in order for a
person to complete a given task. Task
Analysis is helpful when trying to
understand a system and its
information flows.
Why
Provides deep insight into the steps
needed to complete a task. Task
Analysis also helps in understanding
the mental model formed by people
performing the task.
