Question 8 of 143
SPC on the outputs is more preferred than SPC on the inputs when implementing SPC for your process.
Answer

Suggested Answer

The suggested answer is A.

SPC (Statistical Process Control) on the outputs is more preferred than SPC on the inputs because monitoring the outputs directly measures the outcome of the process, ensuring the final product meets the desired specifications. This approach can more effectively detect issues that may affect product quality and performance, leading to faster corrective actions. SPC on inputs, although useful, does not always guarantee that the desired quality will be achieved if there are uncontrolled variables affecting the process after the inputs are measured.

Answer

Suggested Answer

The suggested answer is A, D.

Significant variation in process performance can be classified into two main categories: Common and Special. Common causes, also known as random causes, are the natural and inherent fluctuations that occur in any process. These are typically present all the time and are usually due to the system itself. Special causes, also known as assignable causes, are variations that can be traced to a specific reason, such as a malfunction or human error, and can be corrected once identified.

Answer

Suggested Answer

The suggested answer is C.

One of the most effective means of eliminating defects in a process is to design defect prevention into the product. By incorporating defect prevention measures during the initial design phase, potential issues can be identified and addressed before they occur, reducing the likelihood of defects throughout the product lifecycle. This proactive approach is generally more efficient and effective than reactive measures such as continuous training or ongoing projects.
