What is the purpose of statistical process control?
to check the process variation.
Which variation stems from external sources and indicates that te process is out of statistical control?
Special Cause
Which is a tool of statistical quality control?
Perhaps the most characteristic tool of statistical quality control is the control chart. In its simplest form the control chart is a continuous record of some feature of a process that is deemed to indicate whether that process is 'in control' or not. As long as the control chart shows that the process is within, say, three standard deviations of its mean behaviour it will be considered 'in control'; otherwise not, and steps to correct it taken.Before this system can be put into operation experimentation will be necessary, which implies the need for experimental design. One the system is in place, attempts are often made to find ways of improving the process under control to reduce the number of departures outside the control limits, or to narrow the limits.Please see the link.
How does the statistical process help make informed decisions?
Because statistics tell us what the presents trends are now or were that can be projected into future.
When the only sources of variation in a production process are caused by chance the process is said to be?
In process control.
What is the purpose of statistical process control?
to check the process variation.
Advantages of statistical quality control?
Can improve our process,
What does spc stand for in manufacturing?
statistical process control
What is the difference between SQC and SPC?
SQC or statistical quality control is concerned with using the 7-QC and 7-SUPP tools to monitor process outputs. Statistical process control, or SPC is concerned with monitoring the inputs of the process.
What are the activities involved in statistical process control?
in statistical process control you can make bars and charts as an activity, control charts, process capability, ishikawa diagrams and pareto charts. you can also find controlled variables and chart them to see they're progress based on your experiment.

What are the advantages of statistical process control?
It detects the presence of special causes of variation.
What are qualifications to work in statistical process control?
Qualification to work in Statistical Process Control would include ample mathematics skills, computer skills, and data analysis skills. Also a very good eye for detail.

What are the disadvantages of using a statistical process control?
"In Control" does not mean goodStatical Process Control (SPC) will only help address changes that drive a process "out of control". An "in control" process is unrelated to whether or not the units it produces are acceptable. This concept often leads to the misapplication of statistical process control. That said, when properly understood and applied, SPC can be a power tool for addressing process changes before they result in lost produce.SPC is non-value added, it invested cost on man power is the biggest disadvantage. The advantage is SPC can give you high confidence level on the quality.
