INFOSOURCES
The rapidly increasing power and swiftly decreasing
costs of computers are making it economical to use them
for a growing number of business functions. The purpose
of this Financial Guide, which is directed toward the
user with limited computer experience, is to help you
forecast your computer needs, evaluate the alternatives,
and select the right system. Professional guidance will
be helpful in helping you reach the right decisions.
For the small business thinking of computerizing its
operation, the basic question is what can computerization
offer. To answer this question, you must have a clear
understanding of your long- and short-range goals, the
advantages and disadvantages of the various alternatives
to a computer and, specifically, what you want to
accomplish with a computer.
Before buying a computer, you should compare the best
manual (non-computerized) system you can develop with the
computer system you hope to get. It may be possible to
improve your existing manual system enough to accomplish
your goals.
Business Applications Performed by Computers
A computer's multiple capabilities can, of course,
solve many business problems. Some of the most common
applications are keeping accounting records (such as a
cash receipts journal, receivables ledger, and general
journal) and preparing accounting statements and reports
(such as a balance sheet, income statement or inventory
status report). Other equally important tasks include
maintaining customer and lead lists, creating brochures
and paying employees.
A business that handles large volumes of detailed or
repetitious information in short periods of time will
benefit from computerization. A properly designed
computer system can:
- Organize and store many similarly structured
pieces of information (e.g., addresses including
name, street, city, state and zip code).
- Retrieve a single piece of information from many
stored records (e.g., the address of John Smith).
- Perform complicated mathematical computations
quickly and accurately (e.g., the terms of a loan
amortized over many years).
- Print information quickly and accurately (e.g., a
sales report).
- Perform the same activity almost indefinitely, in
precisely the same way each time (e.g., print a
hundred copies of the same form letter).
- Facilitate communications among individuals,
departments and branches (e.g., quickly transmit
messages and/or documents that require review or
editing).
- Link the office to many sources of data available
through the Internet (as this program, Financial
Strategies Online, helps you to do).
Improving Manual Business Operations
Consider the following manual operations that can be
streamlined by computerization.
Accounts Receivable: Even if properly
organized and maintained, a large volume of active
accounts can require many hours of posting sales and
receipts and, especially, of preparing statements.
Unfortunately, as the volume of information to be handled
increases, the number of errors often also increases.
Don't forget, too, that if your customer isn't billed on
time, you'll wait longer to be paid.
Advertising: Using only
manual systems, it is costly and complicated to have
special sales programs directed toward particular
customers. Manually prepared mass mailings are
time-consuming and expensive.
Inventory: A large number of
items or high-volume turnover can cause major errors in
tracking inventory. Errors in inventory control can
result in lost sales and in the maintenance of
unnecessarily high quantities of slow-moving products.
Payroll: Calculating
and writing checks are tedious operations in payroll
administration. It can also be difficult to effectively
implement an employee incentive plan using manual
procedures.
Planning: Manual systems or
procedures make planning for the future time consuming
and difficult. "What if" situations, such as
"If sales increase, to what extent will expenses
increase?" are not easy to simulate with a manual
system.
Computer Business Applications
Computers also can perform more complicated
operations, such as the following:
- Financial modeling programs can prepare and
analyze financial statements.
- Spreadsheet and accounting programs can compile
statistics, plot trends and markets and do market
analysis, modeling, graphs and forms. They can
combine all these functions and can interchange
and evaluate data from four programs
simultaneously.
- Word processing programs can produce typewritten
documents and provide text editing functions.
Many offer options such as a thesaurus, a
speller, and punctuation and style checkers.
- Desktop publishing programs can enable you to
create good quality print materials on your
computer.
- Critical path analysis programs can divide large
projects into smaller, more easily managed
segments or steps. This helps to target goals and
set dates for completion.
- Legal programs can track cases and tap
information from data bases.
- Payroll system programs can keep all payroll
records; calculate pay, benefits and taxes; and
prepare paychecks.
- File management programs can enable you to create
and design forms, then store and retrieve the
forms and the information on them.
There are some things you should not
expect your computer to do.
- Don't expect a computer to clean up a mess in the
office. The mess must be organized before you can
attempt to computerize, or you will wind up with
a computerized mess.
- Don't install a computer because you don't have
the right people to do the jobs in your
organization. Initially, at least, the computer
will make more, not fewer, demands on your
organization.
- Don't install a computer with the idea that any
information you want will be instantly available.
Computers require structured, formal processing
that may not produce some information as fast as
an informal system could.
- Don't expect the installation of a computer to
help define the jobs that must be done. The
computer is a tool to get those jobs done, but
the jobs must first be well-defined.
- Don't expect computer installation to occur like
magic. Computer selection and installation will
be successful only through methodical work.
- Don't expect any computer system to exactly fit
your present methods of completing jobs. If you
are not willing to listen to new ideas for
solving problems, you will not be able to install
a computer successfully or at a reasonable cost.
- Don't acquire a computer to generate information
you will not use. Growing companies may benefit
from structured management information systems,
but many owner-managers of small companies
already have their fingers on the pulse of their
businesses and do not need a formal, electronic
system.
To determine your requirements, prepare a list of all
functions in your business in which speed and accuracy
are needed for handling volumes of information. These are
called applications. For each of these applications make
a list of all reports that are currently (or will need to
be) produced. You should also include any preprinted
forms such as checks, billing statements or vouchers. If
such forms don't exist, develop a good idea of what you
want - a hand-drawn version will help. For each report
list the frequency with which it is to be generated, who
will generate it and the number of copies needed.
In addition to printed matter, make a list of
information you want displayed on the computer monitor.
Again, design a hand-drawn version. List the
circumstances under which you want this information
displayed.
For each application make a list of all materials used
as input into your manual system. These may include items
such as time cards, work orders, receipts, etc. Describe
the time period in which these items are created, who
creates them and how they get into the system. Also,
describe the maximum and average expected number of these
items generated in the appropriate time period. As
with the reports, include copies of the input items or
drawn drafts.
For all files you are keeping manually or expect to
computerize (such as customer files or employee files),
list the maximum and average expected number of entries
in a specific time period, such as 10 employees per year,
680 customers per year. Normally, a file, manual or
otherwise, is cleaned out after a specified time and the
inactive entries are removed.
Identify how you retrieve a particular entry. Do you
use account numbers or are they organized alphabetically
by name? What other methods would you like to use to
retrieve a particular entry? Zip code? Product purchased?
 |
TIP: Decide on which of your
requirements are a must and those on which you
can compromise. The more detailed you are, the
better your chance of finding programs compatible
with your business. It is also true that the more
detailed you are, the more time it will take to
research and evaluate each alternative
application software package. |
If, after compiling all of your information, you find
your needs are fairly complex, you may wish to engage the
services of a consultant to help evaluate your
software requirements. If, however, you are
extremely knowledgeable about computer programs, you may
be able to make the choices yourself.
You should look for software packages that meet as
many of your requirements as possible. At this point you
should review and compare the software packages and
verify the extent to which each meets your needs.
Consider these questions:
- Does it cover all of your "musts"?
- How many of your other requirements does it
fulfill?
- Does it provide additional features you had not
thought of earlier but now believe to be
important?
After you have identified one or more software
packages fitting your needs, examine other general
features of the software. Consider these questions:
- Does it come with effective documentation?
- Do you understand it?
- Is the operating manual written for the novice?
- Is the information organized so you can use it
effectively after you gain experience?
- How easy is the software to use?
- Does the information displayed on the monitor
make sense?
- Is there a help facility?
- How flexible is the software package?
- Can you change data that have already been
processed?
- Can you change the program instructions, such as
payroll withholding rates, or will you have to
pay the vendor to change these for you? If you
must pay a vendor, what will it cost?
- Will you be required to change any of your
business practices? If so, are these changes you
should make anyway?
- Will the software provide the accounting and
management information you need?
- How well is the software documented? (You should
be able to understand the general flow of
information, i.e., which program does what and
when.)
- Does the software have security features, such as
passwords or user identification codes? Can it
prevent unauthorized access to private
information?
- Is it easy to increase the size of files?
- What kind of software support can I expect?
Choosing the software is by far the most difficult
part of deciding on the computer system that is right for
you. However, you must also make sure that the hardware
is suited to your particular needs.
The computer and associated equipment known as
hardware consist of a number of components that do
different jobs. They include:
- Processor - The thinking part of
the computer, known as the processor or central
processing unit (CPU), is designed to
execute software instructions and perform
calculations. This device will also control
the flow of data, sending it to and from the
memory. The faster the CPU, the quicker you
can work with your data. Processors are measured
in something called a Megahertz (MHz).
Today, the CPU can run as fast as 600 MHz.
Also, different processors are more expensive and
run faster than other brands. For example,
a Pentium III and an AMD K63 w/ 3D Now chips are
considered equal in speed, yet not in
price. The AMD chip is approx. half the
cost; Pentiums are simply more popular.
Pentium Pro's and Calderon's, no matter what the
MHz indicates, will not compete with an AMD or
Pentium II or higher. The reason, chip speed is
generated by heat. Pro's and Caldron's are not
capable of getting as hot.
 |
Note: Despite the fact that
processor chips need to get hot in order run at
an accelerated pace, the CPU still needs to be
cooled down. If it isn't, the computer may
experience difficulties such as a burnt out
motor. To keep the CPU cool, a large fan is
placed inside the unit. The fan
automatically gets activated whenever the CPU
gets too hot. |
- Computer memory - Computer
memory usually is measured in bytes (which is a
grouping of binary digits or bits). Roughly
speaking, each byte of memory holds one character
of data, either a letter or a number. A 2K (2,048
bytes) memory in practical terms holds about one
double-spaced, typed page. There are two
kinds of memory: ROM (read-only memory) and RAM
(random access memory). We are only concerned
with RAM.
- ROM - Read-only memory is a
program stored in the computer memory that cannot
be changed by the user or an externally entered
program
- RAM - Random access memory is
located in the CPU and is normally measured in Ks
or 1024s (64K = approximately 65,536 characters
or about 32 pages of information). RAM is used to
store all the information necessary for the CPU
to do its job: The more RAM, the more programs
you can open at one. Information
stored in RAM lasts only as long as the power is
on. Once the power is turned off, all RAM
information is erased. Store your RAM-based data
on more permanent storage media, such as
diskettes. Programs today require no less
than 8MB of RAM; Most systems utilize between 32
and 128MB of RAM.
TYPES OF RAM- There are three types of RAM,
which run on many types of boards:
- DRAM- Pronounced "dee-ram,"
which stands for Dynamic Random Access
Memory. This type of memory is slower than
SRAM, but cheaper too; it must be consistently
refreshed or it will lose its
contents.
- SRAM- Pronounced "ess-ram,"
standing for Static Random Access Memory. This
type of memory is faster than the more common
DRAM. Static meaning it does not have to be
refreshed, and less volatile; however, it
requires more power to run and is also more
expensive.
- SDRAM- Synchronous DRAM, a new type of
DRAM that synchronizes itself with the CPU's
bus. This new memory is capable of running
at speeds up-to 100 MHz. SDRAM runs at much
greater clock speeds than conventional
memory. Synchronous DRAM is replacing EDO
DRAM.
 |
Note: Two new types of RAM,
which will be coming out soon are: RDRAM and
SLDRAM. Both types will be capable of
running on bus speed of 200 MHz. Today's
PC's top out at 100 MHz. |
- DOS- The disk operating system
(DOS) is software that controls the interactions
among the CPU, disk drive, keyboard, video
monitor and printer. DOS is the authentic
operating system. Windows 3x, 3V or Win98
is not the true operating system, it's more like
wallpaper or frosting that covers over a
cake. Windows is the frosting on the
cake. Without DOS your system will not run;
even if you have Windows installed.
- Storage - Just as a company
retains its relatively permanent records in a
file cabinet, a computer most commonly retains
relatively permanent information on disks. These
resemble small phonograph records and may be
floppy or hard disk. A floppy disk is single- or
double-sided. Diskettes are made of soft, thin
plastic encased in a stiff 3-1/2 paper
envelope. Hard disks are encased in metal
and have faster access and more storage capacity
than floppy disks. Hard disks are also much more
expensive than floppies, but their greater
storage capacity defiantly make up for the
difference in cost. Every 1000 KB= 1MB.
Therefore, every 1000 MB= 1GB and 1000 GB=1
Terabyte; virtually unheard of.
- Floppy Disks hold
between 720K to 1.44 MB. Hard Disks are
nearly unlimited; they range anywhere from 2
Gigabytes GB to 25 GBs. Information on a disk
is recorded, retrieved and erased through a
disk drive, which is controlled by the system
and application software.
- Other devices consist
of Super Disks, CDs, Zips and Jaz Drives.
- The Super Disk is
almost like a floppy, except it holds 120MB
of information opposed to the maximum 1.44MB.
- The CD is
able to hold 650 MB of information, which is
well over 450 floppy diskettes. The CD-ROM
that holds the CD operates in revolutions;
the X indicates 150 revolutions per cycle.
For example, a 40x CD-ROM is 6000
revolutions.
- Zip and Jaz
Drives are basically identical, they
can be internal or external. Meaning they are
capable of being hooked-up to the printer
port in back of the computer or installed in
the CPU just as the Floppy and CD ROM
are. The only differences are the size
and storage space. A Zip holds between
100 to 250 MB a Jaz holds 1 to 2 GB of
information. Also their diameter size
in width is different.
- Terminal. - In order for a
computer to perform useful work, you must be able
to communicate with it. Most often this two-way
communication is carried out through a keyboard,
used to enter data into the computer, and a
display monitor. The monitor (screen) should be
able to display 24 lines of 80 characters at one
time. Some monitors can handle color and
graphics. Color graphics quality is determined by
pixels or picture elements. If a display is 280
by 192 pixels, the screen is divided into 280
rows and 192 columns. The larger the number of
pixels, the finer or more precise the picture
display will be. EGA or VGA monitors are your
best choice for color monitors.
- Printer. - The main output of a
computer system is usually printed material -
reports, checks, invoices, etc. As with all other
hardware choices you make, choose a printer that
can accomplish your specific jobs. The print
quality of various printers ranges from dot
matrix to letter quality. Laser printers have
surged in use because of their high quality print
and speed and because of lowering prices and
increasing interest in desktop publishing.
If your computer needs are so complex that you
need a customized system (not too likely with today's
sophisticated software and hardware), then you and
your consultant should consider:
- The software developer's past performance
record. Does the software developer
have prior experience with similar applications
for the same equipment configuration as the one
you are considering?
- Commitment of the hardware vendor .
Where will your commission sales representative
be after the contract is signed? How many systems
engineers does the vendor have in your area?
- Hardware capacity. Does the
hardware have adequate processing capability to
meet your requirements within acceptable time
frames?
- Quality of systems software. The
quality of the system software (operating systems
and utilities) dramatically affects how difficult
the system is to program and use.
- Systems documentation. What kind
of systems documentation does the vendor provide
and how is it updated? Can it be understood at
some basic level by the user? Is it designed so
other experts can understand how things were done
and change them when necessary?
- Service and maintenance support.
When your system breaks down, how long will it
take to get it fixed? Who will do it? Will it be
subcontracted? Are there any provisions for
backup during downtime?
- Expandability and compatibility.
What are the technical limits of your system and
how close to those limits is your current
configuration? Is there software compatibility
among the vendor's product lines?
- Security. What security features
will your system have to prevent unauthorized use
of the system or unauthorized program
modifications?
- Financial stability of vendors.
Are the vendors financially stable?
- Price.
If you decide to purchase a complete hardware and
software system (turnkey system) rather than buying the
software and hardware separately, you should have a
contract or agreement. Examine the standard contract
supplied by the vendor. Be aware it may not protect your
interests. If you have any questions, have your lawyer
review the contract and suggest changes to help you
implement the system.
An important part of the contract is the payment
schedule. Do you pay before or after installation? Will
you pay for the installation periodically on a draw
schedule? The more money held back until the installation
is complete, the more power you will have to ensure that
the vendor satisfactorily completes all that has been
promised and contracted.
The contract should include detailed references to the
following:
- Description of equipment and software.
- Installation responsibilities.
- Provisions for additional equipment.
- Performance guarantees.
- Responsibility for training.
- Software rights.
- Provisions for default, bankruptcy of vendor or
termination of contract.
- Software documentation.
- Systems documentation.
- Responsibility for hardware freight charges and
sales tax.
- Acceptance testing.
- Conversion responsibilities (from manual system
to computer).
- Upgrading privileges and trade-in rights.
- Restart (what is required to restart system from
failure).
If the contract is for software developed especially
for you, the contract should specifically refer to your
RFP and the vendor's responding proposal. A good contract
will help you prepare for the system's installation and
ensure a more satisfactory business transaction.
Factors to consider when selecting your computer
system include:
- Reliability: How
qualified are the manufacturer and the vendor?
What is their reputation? What is the incidence
of repair on the system equipment?
- Resources: How
long have the manufacturer and vendor been in
business? How strong are their financial
positions and credit ratings?
- Services: Are ongoing
consulting, training, supply and repair
available?
- Rates: Are
charges competitive? What terms are offered?
- Backup: What happens if
your system fails?
As suggested before, successful computer applications
for your business depend heavily on the implementation
process. Problems are inevitable but proper planning can
help avoid some of them and mitigate the effects of
others.
- Employee involvement
The success of a new computer system will
depend on the cooperation of your employees;
therefore, it is important to involve them as
early as possible in the implementation. Explain
to each affected employee how his or her position
will change. To those not affected, explain why
their jobs will remain unchanged.
- Schedule for implementation
Set target dates for key phases of the
implementation, especially the last date for
format changes.
- Installation site: Prepare the installation site.
Check the hardware manual to be sure the location
for your new computer meets the system's
requirements for temperature, humidity and
electrical power.
- Converting applications
Prepare a prioritized list of applications to be
converted from manual to computer systems. It is
important to convert them one at a time, not all
at once. Prepare a list of all business
procedures that will be changed so the computer
system will fit into the regular work flow.
Develop new manual procedures to interface with
the computer system.
- Training Train
everyone who will be using the system.
When these steps are complete, the computer system can
be installed. Each application on the conversion list
should be entered (files set up, historical data entered
and the system prepared for new transactions) and run
parallel with the preexisting, corresponding manual
system for a number of processing periods. This means
that two complete systems will be running, placing a
great deal of pressure on your employees and on you.
However, until you have verified that the new system
works, it will be worth the effort.
 |
TIP: Be sure to insist on progress
reports from everyone involved in the changeover. |
At the same time you are converting each application,
you must begin dealing with the long-term issues that
will keep your computer operation successful.
System Security
If you will have confidential information in your
system, you will want safeguards to keep unauthorized
users from stealing, modifying or destroying the data.
You can simply lock up the equipment, or you can install
user identification and password software. You can also:
- Control access to your computer, disks and
reports.
- Label all disks to identify their contents and
verify correct labeling.
- Initiate original accounting transactions,
adjustments or corrections yourself.
- Rotate computer employees or schedule their
vacations to expose possible unauthorized
practices.
- Require dual signature authorizations to control
software modifications.
Data Safety
Data, confidential or otherwise, can be destroyed by
unexpected disasters (fire, water, power fluctuations,
magnetic fields, etc.) or through employee tampering,
resulting in high replacement costs. The best and
cheapest insurance against lost data is to back-up
information on each diskette regularly. Copies should be
kept in a safe place away from the business site. Also,
it is useful to
- Have and test a disaster recovery plan.
- Identify all data, programs and documents needed
for essential tasks during recovery from a
disaster.
Employee Cross-Training
Just as with a manual system, it is important to have
more than one employee who knows how to operate the
system. Once your business relies on the computer system,
the absence (sickness, termination, etc.) of a computer
operator can be devastating unless another person is
prepared to fill in.
Management Controls
Although computer systems allow small businesses to
process more data more accurately than ever before, there
is a chance that the same system can cause greater
problems if left unsupervised. All systems, manual or
otherwise, must be continually monitored to ensure the
quality of the input and output data.
If all this seems like a lot of work, it is. The
computer, like any tool, requires learned skills in order
to fulfill its purpose properly. If you believe that you
and your business need a computer, plan to spend the time
and the money it takes to make its installation and
operation of the system successful.
With little knowledge of computers, you can buy a
personal computer with applications for your business.
With some guidance, study and experience, you can develop
computer-based management planning and control expertise.
By taking advantage of the speed and complex capabilities
of a computer, you can tap the potential for growth and
profit in yourself and your business.
Technology is continually evolving. Personalized
guidance on the state of current technology in choosing a
system which will both meet current needs and grow with
your business, will be very helpful.
