SPC versus Process Capability

Quality engineers and process engineers often make the mistake that they use statistical process control also for process capability evaluation, and they are not sure about the difference in use of these tools.

Both statistical tools are very useful for any technologist or quality engineer. However, it is necessary to be sure, what is the purpose of each of them, and what information it provides to us. It is often the case that statistical outputs are not interpreted correctly, and we often miss their original purpose. Statistical process control (SPC) is based on regular monitoring of process outputs, while Process Capability compares process outputs with specification, and measures the ability of a process to meet this specification.

Can you correctly set up data collection for SPC?
Do you know when a process is really unstable?
Do you know that the control techniques are different for each process?
Do you know how to set the correct regulation schedule?
How does this all relate to stability?

Our colloquium will make clear the difference between both of the tools. They will be explained in depth, and you will learn the correct usage and interpretation of outputs. You will understand the difference in approach and concept of each tool, and you will be able to avoid future mistakes in their application.
