Title: An applicant has adopted the Six Sigma quality program' For his Six Sigma Black Belt project, an app


1
Example An applicant has adopted the Six Sigma
quality program. For his Six Sigma Black Belt
project, an applicants manager has dramatically
reduced costs by striking a deal with a local
computer recycler to provide them with salvaged
Intel 8086 processors from PCs built in the early
1990s. However, there is some concern about
whether the throughput of this chip will support
intense graphic operations, such as moving the
cursor. Initial testing shows that cursor
positioning lags pilot input by about 130 ms. Use
the Job Aid to find the information you would use
to determine if this is likely to be a problem.
2
Starting at the default view, we'll choose the
Index tab in the upper left pane.
3
cursor
To find information related to the effect of lag
time and cursors, well type the word cursor in
the keyword field.
4
Notice that the definition of cursor is
provided in the lower left pane.
5
Control, display, and system-related Human
Factors (HF) Considerations that pertain to
cursors are presented in the upper right pane.
6
Since the problem involves the time lag in
updating cursor movements, the Display-related HF
Consideration related to "Timing of information
presentation is appropriate" appears most
relevant.
7
Well select this HF Consideration by
left-clicking on the title.
8
Summarized information for this HF Consideration
is provided in the lower right pane. We can
enlarge this pane by pressing the maximize
button.
9
The Human Factors Information tab includes
summaries of human factors guidelines and
research findings related to a variety of
specific topics. We'll select this tab by
left-clicking on it.
10
The topics addressed section describes any
specific areas addressed in this summary. We'll
use the vertical scroll bar to show more of these
topics.
11
Among the topics addressed, "Information update
rate is fast enough" contains information about
"visual displays that indicate motion...". This
may have relevance to the cursor time lag issue.
12
This is the subtopic summary page. The page
overview presents an outline of the content.
Scroll down to see what is in each section.
13
The General section presents a high-level
overview of the main subtopic.
14
The Design Strategies and Examples section
contains descriptions and examples of strategies
that have been used to address the subtopic.
15
The Measures section describes specific
parameters that pertain to the evaluation of the
display or the information presented by it.
16
This section of text in Measures states,
"Processing delays associated with graphic
objects moved by the pilot (such as cursors)
should be less than 75 ms. Delays higher than 120
ms may be perceived as unacceptable".
17
Sections of text can be copied and pasted into
other word processing or database applications
for subsequent use in a report. We'll highlight
the text to be copied by positioning the cursor
at the beginning of the text, pressing the left
mouse button, and dragging to the end of the text.
We can copy the highlighted text by using Edit gt
Copy from the main toolbar, by using the hotkey
sequence, Ctrl-C, or by right-clicking and
choosing Copy from the pop-up menu. Once copied,
this text can be pasted into any text editing
application.
18
References for summary statements are represented
by the green hyperlinks. Pressing any reference
link will bring up a pop-up window with the full
text reference.
19
As with other text, reference citations can be
copied from the Job Aid and pasted into other
text editing programs.
