Statistical process control (SPC) is a method of quality control that uses statistical methods.

True
False

Correct Answer

A. True

Explanation

Statistical process control (SPC) is indeed a method of quality control that utilizes statistical methods. SPC involves monitoring and controlling a process to ensure it operates within predetermined quality standards. By using statistical techniques, SPC helps identify any variations or abnormalities in the process, allowing for timely adjustments and improvements to maintain consistent quality. Therefore, the given answer, "True," accurately reflects the relationship between SPC and statistical methods in quality control.

Advantages of the SPC Process are:

Dramatically reduce variability and scrap.
Scientifically improve productivity
Reduce costs
Instantly react to process changes.

Correct Answer(s)

A. Dramatically reduce variability and scrap.
A. Scientifically improve productivity
A. Reduce costs
A. Instantly react to process changes.

Explanation

The SPC (Statistical Process Control) process offers several advantages. Firstly, it helps in dramatically reducing variability and scrap, which means that it minimizes inconsistencies and defects in the production process, leading to improved quality. Secondly, it enables scientific improvements in productivity by providing data-driven insights and analysis, allowing for more efficient and effective operations. Thirdly, it helps in reducing costs by identifying and eliminating waste, optimizing resources, and streamlining processes. Lastly, the SPC process allows for instant reaction to process changes, enabling timely adjustments and improvements to maintain quality and efficiency.

Special Cause Variation charts indicate the following:

Machine malfunction
Poor adjustment of equipment.
Faulty controllers
The poor batch of raw material
Operating procedures

Correct Answer(s)

A. Machine malfunction
A. Poor adjustment of equipment.
A. Faulty controllers
A. The poor batch of raw material

Explanation

The correct answer indicates that Special Cause Variation charts can help identify machine malfunctions, poor adjustment of equipment, faulty controllers, and the poor batch of raw material as potential causes of variation in a process. These charts are used to identify specific factors that are causing the process to deviate from its normal or expected performance. By identifying and addressing these special causes of variation, organizations can improve the quality and consistency of their processes.

SPC Common Cause Variation charts explain:

Poor maintenance of machines.
Ambient temperature and humidity
Machines not suited to the job.
Machine malfunction

Correct Answer(s)

A. Poor maintenance of machines.
A. Ambient temperature and humidity
A. Machines not suited to the job.

Explanation

The SPC Common Cause Variation charts explain various factors that can contribute to variations in a process. Poor maintenance of machines can lead to inconsistencies in performance, while ambient temperature and humidity can also affect the process. Additionally, using machines that are not suited to the job can introduce variations. These factors are all examples of common causes of variation that can be identified and monitored using SPC charts.

Statistical Process control is implemented and applied to

Monitor progress
Assist in MIM Degisn
Reduce or eliminate process waste
Evaluate the manufacturing process

Correct Answer

A. Reduce or eliminate process waste

Explanation

Statistical Process Control (SPC) is a method used to monitor and control a manufacturing process. By collecting and analyzing data, SPC helps identify any variations or abnormalities in the process. One of the main goals of SPC is to reduce or eliminate process waste, which refers to any inefficiencies or defects that occur during the manufacturing process. By identifying and addressing the root causes of waste, SPC helps improve the overall quality and efficiency of the process, leading to cost savings and increased customer satisfaction.

Statistical Process Control answers the question: "Is the process stable?"

True
False

Correct Answer

A. True

Explanation

Statistical Process Control (SPC) is a methodology used to monitor and control a process to ensure its stability and quality. By analyzing data collected from the process, SPC helps determine whether the process is stable, meaning it is operating within acceptable limits and producing consistent outcomes. Therefore, the statement "Statistical Process Control answers the question: 'Is the process stable?'" is true, as SPC is specifically designed to address this question.

Root Cause Analysis in the SPC process explains:

Why and What happened
Materials and Equipment needed
Variations in the molding process
Statistical norms in the CC chart

Correct Answer

A. Why and What happened

Explanation

Root Cause Analysis in the SPC process is a method used to identify the underlying reasons and events that led to a particular outcome or problem. It aims to determine the "why" and "what" of the situation, providing insights into the causes and contributing factors. By analyzing the root causes, organizations can take appropriate actions to prevent similar issues from occurring in the future and improve overall process efficiency. This analysis helps in understanding the sequence of events and identifying the key factors that influenced the outcome.

Statistical Process Control was invented by

Walter White
Walter Whitman
Walter Disney
Walter Shewhart

Correct Answer

A. Walter Shewhart

Explanation

Statistical Process Control was invented by Walter Shewhart. He was an American physicist, engineer, and statistician who developed the concept of statistical process control in the 1920s. Shewhart's work laid the foundation for modern quality control methods and helped revolutionize industrial production by emphasizing the importance of measuring and analyzing process data to improve quality and reduce variability. His contributions have had a significant impact on the field of quality management and continue to be widely used in various industries today.
