it is the use of charts called "control charts" to monitor a process. it is a very objective method of monitoring. it involve the collection data from the process. hence it makes identification of the cause of problem in the process easier.
Statistical process control (SPC) is the application of statistical methods to the monitoring and control of a process to ensure that it operates at its full potential to produce conforming product. Under SPC, a process behaves predictably to produce as much conforming product as possible with the least possible waste. While SPC has been applied most frequently to controlling manufacturing lines, it applies equally well to any process with a measurable output. Key tools in SPC are control charts, a focus on continuous improvement and designed experiments.
Statistical process control (SPC) is defined as the use of statistical techniques to control a process or production method. SPC tools and procedures can help you monitor process behavior, discover issues in internal systems, and find solutions for production issues. It will confirms that the process or machine is capable of producing the part within specification of that critical parameter. This study will also confirms that the process is running with common cause only and not with special cause. They are explained in detail in our YouTube channel “New Mechanical Mind” . Pls see below video for more details.

Can improve our process,
It detects the presence of special causes of variation.
It allow industry to qualify process and potential success or failure
Cp is the capability of a process and Cpk is the actual capability of a part running in the process. The only way Cp = Cpk is if the process mean is exactly centered which is seldom the case in manufacturing. Therefore, Cp > or = to Cpk.
The definition to the term "Stochastic Process" is: A statistical process involving a number of random variables depending on a number variable. Which in most cases, is time.
to check the process variation.
Explain the difference between capability and control.

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.
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.

It detects the presence of special causes of variation.
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.
