CASE STUDY

Buckeye Technologies is a manufacturer of semiconductors for mobile consumer

electronic devices, such as laptop computers, smart phones, and digital cameras. Ms.

Sabina Norton has been working at Buckeye Technologies for about a year as a

production manager. The volatile demand of the semiconductor industry has been

an obstacle in designing an accurate production schedule. The unstable demand causes

the company to carry high amounts of safety stock and incur other types of wastes.

Sabina is wondering if the operation can be modified to become more efficient.

Transistors are key components used in the manufacture of a semiconductor.

One of the transistors of a cell phone semiconductor is sourced from Xiang, a supplier in

China, with a lead time of two months. Buckeye Technologies usually carries enough of

these transistors at the plant. When it runs out of them, however, they experience high

levels of work-in-process (WIP) inventory and are unable to continue with production.

Although this transistor can also be obtained from several suppliers in the United States,

the cost is considerable higher compared to the cost of sourcing it from Xiang.

The semiconductors for laptop computers, smart phones, and digital cameras are

produced differently, so every time the company needs to produce a different type of

semiconductor, the operator is required to change the setting of the production

machinery. This can be time consuming, and the company wants to be able to respond

quickly to changes in demand. Sabina knows that there must be a way to reduce

inventory, but at the same time she wants to keep a flexible production to keep up with

the fast paced environment and the volatility of the demand.

Sabina has also noticed that the current design of the facility is not very efficient.

Currently the facility production system is grouped by function and components move

from function to function. There are about 350 steps in producing a semiconductor

chip. Some functions of the facility are located at one end of the facility, while other

functions are at the other end of the facility. This results in long waiting times between

procedures. She is thinking about changing the design of the facility to one that will give

more flow to the production process.

Sabina recognizes that there are a number of changes that must be made. She has

heard of Lean as a method to reduce waste but is not sure where to begin.
