Final answer:
An SPC program is likely implemented to improve product quality control by using statistical methods to monitor and control a process, leading to more efficient production and higher-quality output.
Step-by-step explanation:
The likely purpose of implementing a Statistical Process Control (SPC) program in the foundry department is b) Improve product quality control. SPC is a method of quality control which employs statistical methods to monitor and control a process. This helps ensure that the process operates efficiently, producing more specification-conforming products with less waste (rework or scrap). SPC can also lead to a better understanding of the process by the workers and can be used as a tool to increase their productivity. The goal of scientific management, which is closely related to SPC, was a) to increase workers' efficiency. Moreover, some of the intended positive aspects of bureaucracies, such as increased efficiency and productivity, are also objectives that SPC seeks to achieve within a manufacturing environment.
