At a Stereo Making Factory, the Employees Stationed Along the Assembly

At a stereo making factory, the employees stationed along the assembly line are required to wear ring scanners, small electronic devices worn on their index fingers and wired to a small computer on their wrists. As a product moves along the assembly line and is handled by the stationed employee, its location or progress is updated on the company's database system. This way the management knows if there are any bottlenecks. This method of improving operations allows the company to:

A) improve its productivity.
B) decrease fixed cost.
C) decrease its dependence on its Web site.
D) increase customer affective responses.
E) manage quality.
