Definition: Statistical Process Control
Statistical process control is a way of controlling quality using statistical methods. SPC is used in controlling and monitoring of the process. Statistical process control ensures that process runs at its full potential. At its full efficiency process makes sure it manufactures products with same conformity and wastes minimum possible resources.
This can be applied to any process given the process can measure conforming product output. Quality data in form of measurements is obtained and data is then plotted on graph. Control limits are available on graph and you can check data against them.
Some of the instruments used are:-
1. Control Charts
2. Design of experiments
3. Continuous improvement
Example- Used in manufacturing lines
SPC must be used in two phases
1. During the intial establishment of process
2. Regular production use of process
Advantages- One advantage over other methods is early detection of problem rather than correction of problem. Other can be it reduces likeliness that product will comeback for re work. It also reduces time required to produce the product.
