Barcode System
The main benefit of using barcode is
Cost Savings. Bar code (automatic identification
technology). Allows real-time data to
be collected accurately and rapidly.
Bar code by itself does not solve problems
Combination of bar code with computer
hardware and application software
creates potential for improving performance,
productivity, and profitability. Reduce
Errors, Increase Productivity, Increase
Accuracy.
Manual data collection/data entry
systems are:
- Slow and error prone
- Barcode: Significantly faster,
(about 20 times)
- Barcode: More accurate, (about
20,000 times)
- Manual systems characterized by
Information Float
- Batch oriented, so databases often
out of date
- Barcode data entry can save hours/days
of "Information Float"
(time between event and entry into
information system
- Expensive and error prone means
companies discouraged from collecting
important information
- Consequences: Significantly higher
costs ripple throughout entire organization
(even entire industries)
Accuracy
- A well-trained data entry operator
makes a data entry error once every
300 keystrokes.
- Leads to waste of time and lost
revenues
- Even in worst case, using barcode
clearly reduces errors during data
collection.
Investment in barcode can pay
for itself in three ways:
- Increasing Sales
- Improving Gross Margins
- Reducing Overhead
Some benefits are easily measured.
(i.e. keeping customers). Others
more difficult to predict with
certainty (i.e. increasing sales
due to improved customer service).
Any barcode application can be
analyzed by impact on sales, gross
margins and overhead.
Problem: The high cost of inaccurate
inventory records
Theoretically, inventory records
should always be perfectly accurate.
If every transaction recorded in
"real time," inventory
will be accurate. Realistically,
however, daytoday mistakes
throw accuracy off.
One solution: take inventory
more often to detect cause of inaccuracies.
Traditional inventory-taking is
not a pleasant task. Discourages
companies from counting inventory
as often they should. Leads to inaccurate
inventories: not knowing what is
on hand or where it is stored.
Consequences of inaccurate inventories
Lost sales
- If you tell a customer you
dont have something when
you do, you may lose a sale.
- If you miss a delivery date,
you may lose an order.
- Damaging your reputation with
a customer due to late deliveries
eventually causes lost sales.
Lower Margins
- Buy from a competitor to supply
a product you thought you had
but didnt; your margins
suffer.
- Tell a customer to keep a product
shipped by mistake rather than
pay to have it returned.
- Pay RUSH transportation costs
to expedite an item you thought
you had but didnt.
- Pay higher prices to vendor
to ship small quantity of product
because you didnt have something
you thought you had.
Higher Overhead
Inaccurate inventories often lead
to purchasing buffer inventories
which causes lower inventory turns.
Lower material handling productivity.
The productivity of material handlers
can be reduced if inventory records
are inaccurate because they waste
time trying to find merchandise.
Solution: Using barcode
is easier, more accurate and faster
than manual methods.
Problem: The high cost of picking
and shipping errors
When the wrong product, or the wrong
quantity of the right product, is
sent to a customer it initiates several
costs.
Lost Sales
Lower sales impact productivity.
Shipping errors irritate customers.
They take it out on the sales force.
Rather than selling, the sales force
winds up apologizing and spending
time and money trying to keep a
customer.
Undetected over-shipments lead
to inventory inaccuracies which
can lead to lost sales.
Lower Margins
Undetected over-shipments by definition
are shipments with no corresponding
invoice. This shows up as reduced
overall gross margins.
Higher Overhead
Customers frequently delay paying
incorrect invoices even if
most of the invoice is correct.
Delayed payment reduces cash flow
and increases borrowing costs.
Picking up the incorrect merchandise
and re-shipping the proper merchandise
increases transportation costs.
Material handling productivity
is reduced if merchandise shipped
in error needs to be re-stocked
and if the correct merchandise needs
to be picked again.
Issuing credits and rebills (debit
memos) consumes administrative time
and money. Some portion of one or
more persons salary goes to
researching these errors and issuing
the necessary paperwork.
Example
A company issues 200 invoices per
day, 240 days a year. They process
10 credits / rebills a day (5%). 50%
because they made a picking, packing
or shipping error (5 per day). 50%
customer errors or errors out of their
direct control.
The total number of errors under
their control per year is 1,200 (5
per day @ 240 days). At an average
cost of $75.00 per error (administrative,
material handling, transportation,
etc.), the total cost of errors is
$90,000 a year. Actual cost may be
double since the detected errors are
brought to your attention by customers
when you make an error in your favor.
Errors in their favor may never be
reported. It is noteced as inexplicable
low gross margins or inventory adjustments.
Shipping errors drive costs at both
the sender and the receiver side.
Costs above dont include cost
to recipient which should be included
in overall cost of errors to an industry.
Solution: Barcode-assisted
order picking and shipping verifications
systems pay for themselves by reducing
these costly errors.
