Explain the difference between capability and control.
statistical process control
Can improve our process,
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.
The disadvantages of statistical quality control include the time it adds to the overall production process and the cost of the extra manpower needed to carry out the quality control.
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.
