How big are the differences between DJC' plant and ACC's Sunnyvale plant?
Consider both DJC's potential in Kawasaki and its potential in America
What s for these differences? How much of the difference is inherent in the
way in which these two companies compete? How much is due strictly to the efficiency of operations?
KAWASAKI PLANT Objective: The ultimate rationalization of mass production Vision: A highly automated, continuously operating plant which could meet the following goals• Asset utilization of 100% • Yield on raw material 99% • Customer complaints <1 per million units of output Advantage: located close to the major Japanese electronics companies and major raw material suppliers and ample supply of relatively young, highly skilled workers Wire-towire Plant layout: Four large cells each responsible for one of the four types of connectors
Wire-tooutlet
Item-toboard
Board-toboard
Each cell- 2 to 6 production lines Each production line Terminal stamping
Housing molding
Assembly
Packaging
Factors
Decisions and policies
Product Technology
-
Product design of most connectors was standardized to reduce the number of product variations Tin was used instead of gold in order to economize Connectors were packed on tape and reels Extensive value engineering was performed to implement cost saving changes without compromising on quality
Process Technology
-
Significant resources were allocated to pre-automation It was possible for one operator to run two assembly lines To ensure smooth runs, processes were generally operated below maximum speed Molding was particularly considered to be very significant and received daily maintenance Relied on in-house technology development There was inter-functional coordination of all its technology development activities
Sourcing
-
Maintained close relationship with suppliers and quality was considered a t effort Suppliers required to certify the quality of products in every delivery It demanded frequent delivery, most on daily basis and few on weekly and monthly basis
Quality Control
-
Pursued five objectives; improving quality control standards, process inspection system, precision of molded components, quality of product designs and reducing the plant’s waste
Production and Inventory Control
-
Production runs were scheduled to be as long as possible and changes were not made for unplanned orders Work-in-process inventory was minimized to devote few resources to inventory control
Workforce
-
General approach to selecting workers was to hire new graduates from high schools for lower level positions and from universities for higher level positions Wages offered were above average for recent graduates in Japan and below average for experienced workers.
-
Organization
-
The goals were set, but the plant manager was free to assume those in a way he chose The tactical problems were solved by production employees and plant manager, top staff was responsible for long term planning issues
Sunnyvale Plant: • Always had been a technological leader in the past but currently on the verge of losing that statues because of excess unutilized capacity for more than 5 years now. • The plant produced ~4500 different models • It was typically a process focused organization • Emphasized on maintaining healthy relationship with big clients by accepting customized orders even after finalization of production schedule Plant Layout: Bottle-neck process

Comparison of DJC’s potential in Kawasaki and USA:
DJC/ Kawasaki, 1991 ACC/ Sunnyvale, 1991 Product Raw Material 12.13 9.39 Packaging Raw Material 2.76 2.10 Direct Labor 3.02 Indirect Labor 0.75 Total Labor Costs 3.77 10.30 Electricity 1.40 0.80 Depreciation 1.80 5.10 Other Costs 4.24 6.10 Total Costs 26.10 33.79
DJC/ USA, 1991 7.28 1.66 3.32 0.83 4.15 1.12 1.80 4.24 20.24
DJC in US is a substantial threat to ACC in a highly competitive market
Reasons for difference
Production process
High product variation led to frequent batch changes in ACC(1.5~2 days) reducing efficiency and expertise on any product.
Utilization
Continuous runtime at Kawasaki increases its overall utilization and also higher per employee output adds to efficiency at DJC
DJC had lesser variations and product focussed plants(similar to PWP) with average runs of 7 days
“Pre-automation” and similar such guidelines and disciplined practises ensured efficiency
Quality
Defect rate at Sunnyvale is too high at 26000 dpmo due to the final product inspection and newer measures like implementation of SPC and other measures have shown minimal progress DJC utilizes process inspection and thus better control; quality losses of DJC and ACC over total production are 0.7% and 1.6% which is substantial
Cost
Cost comparison indices of US/Japan indicates that Raw material and electricity is cheaper in US while labour is cheaper in Japan
Cost advantages to ACC will be lost once DJC enters US
Material Cost savings due to design changes : $6.01 per 1000 units DJC’s wise investment in technology development and lower mold life helped them in achieving less depreciation cost(6.89% contribution to total cost as against 15.09% for ACC)

DJC
• • •
• Highly flexible and driven by marketing/sales team
Process focus
More cost or time consuming
• Carefully planned schedules tightly connecting processes with manufacturing favoured
Product focus
Highly optimized for cost and time
Process wise, both are optimized and operate at highly efficient scales; however DJC has a more focussed manufacturing strategy that allows lesser variations but is much more efficient. The suitability of the processes is the major reason for cost advantage to DJC For example, ACC uses only final inspection as its quality measure while DJC undertakes process while quality checks that ensures lesser defects in the final product
Efficiency of operations are not the major source of the cost differences, it is whole process that needs to be adapted to better scale
