(U)
Each step requires specific considerations.
Some considerations
already delineated by the date
of this publication
are:
A.
(U)
First,
establish
the system's OUTPUT requirements :
Some
important considerations
are:
1.
(U)
Printed material
requi rements :
Printed matter
in
the
form of reports,
database summaries,
etc.
makes
up
the bulk
of
an
office's computer
usage.
It
is
the
most visible and long-lasting output
the system will
make.
It
is therefore
the
most important Output
consideration.
Report types,
quantity and quality of print,
single
vs.
multiple sheet
printing,
etc.
must
be considered
in order
to build
a
system which will
meet
the unit's
needs.
Figure
contains
a listing of
the printed output requirements
this office had when
the
last systems
analysis
was performed.
A more up-to-date
listing
will accompany a more
detailed report.
There are
three basic forms of printers:
a.
<U)
"Daisy wheel"
(also called
"letter quality,
even
though all
three types can produce
letter-quality print").
This printer
has a rotating wheel
which strikes the paper,
leaving an impression of
the
letters.
It
is slow,
loud,
has very little flexibility for
specialized purposes.
It does
not have any graphics capability.
b.
(U)
"Dot Matrix"
(including
"ink jet").
This
printer has
a "print head",
containing small
pins which strike out
in the
required patterns to print text or graphics.
It
is more compact,
less
noisy,
and very flexible for specialized purposes.
In fast mode,
the
letters and graphics are made of coarse dots.
In slow mode,
the dots can
barely be seen,
but
the slow mode
is very time-consuming,
and usually
keeps
the user from any other activity on the computer while printing
takes
place.
Printed output,
especially graphics,
is usually of less
quality than desired.
c.
(U)
"Laser".
This printer uses a laser to form an
image on a xerox drum which
is then transferred to the paper.
It
is
fast,
quiet,
does text and graphics with extremely professional
looking
results.
However,
it
will
not do carbon copies,

(U)
Graphics output requirements :
a.
(U)
With the modern trend toward presentation
in
graphic format rather than as printed text,
graphics requirements are a
major concern.
Figure
includes the graphics requirements,
since almost
all graphics are printed before being changed to other presentation
formats.

Another form of graphics output
is that of
.
l
Thic: adds both color and motion
impact
projection-type computer monito
.
.
.
There are two basic forms
to presentations and to computerized training.
There are two oas
of projection equipment for this purpose:
1)
The Overhead Projector Slide Screen:

a
monochrome monUor

cost
of
this type of monitor
is approximately $400,

2)
A dedicated projection monitor.

monitor has a standard color monitor with

3 .
(U)
Database presentation requirements
a.
Will output be merged into other output or stand
n 1 nn flO
b.
Will data output require accompanying graphics?
c.
Will database software be compatible with other
software being used on the system?
d.
What other equipment
is necessary for output.
1)
Printer or plotter
2)
Modem
(for tele-output)
- does this need to be a
secure
line with crypto?
3)
Projection screen terminal
(for briefings)
4)
Color
vs.
monochrome

B.
(U)
Second,
establish the system's
INPUT requirements :
Having
established the OUTPUT requirements shows the planner what
INPUT hard-
and software
is needed.
For example,
if maps are to be included
in
presentation graphics
as part
of the output,
maps
will
need to be
INPUT.
There
is only certain equipment which can digitize maps and put them into
the computer,
and the planner
is automatically pointed
to the need for
such equipment.
Beyond the obvious
input requirements,
however,
there are other
considerations:
1.
(U)
How labor
intensive
is the
input?
Is
there equipment
on
the market
which
will
be cost effective,
due simply to
a savings
in
man-hours saved?
2.
(U)
How user friendly
is system?
No matter
what the
system costs,
it costs too much
if the user will
not
use
it.
3.
(U)
What other equipment
is necessary for
input?
The
basic system rarely ever has everything you need for any work which
is
more advanced that
just text or data
input.
For the program's purposes,
the following input devices need to be evaluated:
a.
(U)
Graphics digitizer :
This
input device
is much
like a xerox machine,
but instead of a copy of the original,
will
digitize pictures,
sketches,
artwork,
etc.
into a format which can be
incorporated into word processing documents,
briefing slides,
etc.
This
is a graphics only device.
b.
(U)
Optical Character Reader :
This input device
is
also like a xerox machine,
but will read a document and input the text
into word processing documents.
This
is a text only device.
c.
(U)
Modem :
This input/output device connects the
system,
through phone
lines,
to other computer systems,
databases,
etc.
It allows the system to draw off data and information from other sources,
send documents to other sources,
etc.
Secure modems may or may not also
require:
1)
A Crypto device for encipherment of the data,
documents,
etc.
2)
A secure telephone line for transmission.
d.
(U)
Special
input devices specific to the program's
