1. goal of EBP - ANSWER is improvement of systems and microsystems
within healthcare, with these improvements based on science
2. human factors - ANSWER is "the scientific discipline concerned with the
understanding of interactions among humans and other elements of a system,
and the profession that applies theory, principles, data and methods to design
in order to optimize human well-being and overall system performance."
3. In healthcare, human factors might concern the design of a new operating
room to better support teamwork and patient flow.
4. ergonomics - ANSWER used interchangeably with human factors by the
HFES in Europe but in the U.S. and other countries its focus is on human
performance with physical characteristics of tools, systems, and machines
i.e. power drill fitting in hand
5. Human-computer interaction (HCI) - ANSWER is the study of how people
design, implement, and evaluate interactive computer systems in the context
of users' tasks and work
6. usability - ANSWER is often used interchangeably with HCI when the
product is a computer but usability also concerns products beyond
, computers. Usability is also more focused on interactions within a specific
context or environment for a specific product.
Formally, the ISO defines usability as the extent to which a product can be used
by specific users in a specific context to achieve specific goals with
effectiveness, efficiency, and satisfaction.
allows users to achieve goals
7. joint cognitive systems - ANSWER imply that information is shared or
distributed among humans and technology. This framework is useful for
examining teamwork in healthcare where team members work together on
patient care
8. Health Human-Computer Interaction (HHCI) Framework - ANSWER
Humans or products can initiate interactions. The information is processed
through either the product or the humans according to characteristics. The
recipient then reacts to the information; for example, a healthcare provider
could read and respond to email from a patient or a product might process
interactions after the "enter" key is pressed. Iterative cycles continue as
humans behave and products act according to defined characteristics. Goals
and planning are implicit within the tasks displayed in the framework.
9. discount usability methods - ANSWER reduce the number of required users
in usability projects and to use early design prototypes.
These methods offer economies of time, effort, and cost and can be completed
at any point in the systems life cycle.
Two common techniques are heuristic evaluation and think-aloud protocol.
,10.Heuristic evaluations - ANSWER compare products against accepted
usability guidelines to reveal major and minor usability issues.
11.think-aloud protocol - ANSWER also involves a small number of users and
has them talk aloud while they interact with a product. Users voice what
they are trying to do, indicate where interactions are confusing, and provide
other thoughts about the product during interactions.
This allows a detailed examination of the specified tasks, in particular to
uncover major effectiveness issues.
used in conjunction with other techniques
12.task analysis - ANSWER generic term for a set of more than 100 techniques
that range from a focus on cognitive tasks and processes (called cognitive
task analysis) to observable user interactions with an application (e.g., a
systematic mapping of team interactions during a patient code).
Task analyses are systematic methods that are used to understand what users are
doing or required to do with a product by focusing on tasks and behavioral
actions of the users and products.
These methods provide a process for learning about and documenting how
ordinary users complete actions in a specific context.
Methods of task analysis include the following: •Interviews •Observations
•Shadowing users at their actual work sites •Observing users doing tasks
•Conducting ethnographic studies or interviews
, 13.focused ethnographies - ANSWER concentrate on individuals' points of
view, their experiences and interactions in social settings, rather than on just
the actions of those individuals
During observations, detailed descriptions are generated with an emphasis on
social relationships and their impact on work.
14.Usability Questionnaires - ANSWER System Usability Scale (SUS)-
industry standard, 10-scale
Questionnaire for User Interaction Satisfaction (QUIS)-computer system or
application assessed
Purdue Usability Testing Questionnaire-100 open ended questions
Software Usability Measurement Inventory (SUMI)-
15.Exploratory Test - ANSWER conducted early in the systems life cycle after
requirements are determined. These tests are conducted on very basic or
preliminary designs or redesigns where few resources have been committed
to programming the product. The objective of an exploratory test is to assess
the effectiveness of emerging design concepts
informal
16.Assessment Test - ANSWER conducted early in or midway through the
development of a product application. After the organization and general
design are determined, this kind of test assesses lower-level operations of the
application, stressing the efficiency goals of the product (versus
effectiveness) and how well the task is presented to users.
