Q.4
CASE STUDY:
Suzuki Motorcycle Limited
Every Suzuki motorcycle has a unique frame number and a unique engine number.
Once these numbers are paired, they define the identity of the motorcycle and hence
they must always stay together. But some engines have to be dismounted from their
frames and sent for repairs after they have been paired at the invoicing stage. The
company relied on a manual process to recombine the frame and the engine, and it
often happened that an engine was mounted on a wrong frame. In terms of
performance, there is no problem with the bike whose frame number and engine
number do not match, but the owner can not register it.
The engines and the frames had barcodes on them, but they were not used in the
production process. The invoice team used them in coupling an engine to a frame.
The company decided that barcodes would be used in the manufacturing process and
a scanner was provided at the point when an engine was mounted on a frame.
Scanners were also provided to operators who remounted the engines on the frames.
The operator scans the engine's barcode and then puts it on the right frame.

Q.5
CASE STUDY:
TVS Motor Company
TVS Motor Company is the third largest two-wheeler company in India and is
among the top ten in the world. The company exports its vehicles unassembled to
reduce shipping costs. It was facing problems in the order-fulfillment process. The
order-fulfillment process was entirely manual without any control integrated into the
process and the employees walked through the company's warehouse fulfilling each
order. The process resulted in missing or mismatching parts, and the company had to
incur extra costs to reship the correct parts. The company lacked visibility of its
packing, and shipping processes, and it could not track the orders to final delivery.
Its operating expenses were very high, and a large number of employees were
required to fulfill orders.
The company has been using SAP ERP, and it decided to customize it to improve its
order-fulfillment process. It integrated barcode and wireless technology with the
sales and distribution function of SAP ERP. It developed a cart that houses a
scanner, a barcode printer, and a weighing scale that communicates wirelessly with
SAP ERP. Each part's exact location is transmitted to the cart, and hence employees
do not waste time looking for them. Employees do not now count the parts such as
nuts and bolts that are shipped in quantity. The parts are weighed on the cart's scale,
and when the predetermined weight is reached, a barcode sticker is generated. SAP
ERP also ensures that orders are optimally packed an arranged in shipping containers
to maximize utilization of space and reduce freight costs. The company was able to
eliminate missing and mismatched parts in its export orders and since SAP ERP
provides full traceability of international shipment, it can address customer order
inquiries quickly. Productivity has improved dramatically. Earlier an employee
walked9.6 KM to fulfill 90order, but now he has to walk just 40 meters to fulfill the
same order.
