There are a number of ways to control the output of a process,
whether that process is producing a material good or a service. Here are some
ways to control a process.
| Technology |
Description |
| Robust Product and Process Design |
Design of Product and Process characteristics to minimize
effects of process variation |
Statistical Process Control
a) Stability Improvement
b) Adjustment |
a) Monitor process to identify sources of process change
followed by prevention or recurrence
b) Monitor process to identify when
adjustment is required |
| Mistake-proofing (Poka-yoke) |
1) Physical methods to catch and prevent human error
2)
Physical methods to provide attention to an error |
| Autonomous Control (Jidohka) |
A method used to automatically stop a machine whenever a
defective part is produced |
| Electronic Feedback and Control Systems |
Means of electronically monitoring and adjusting processes on
a continuous basis |
| Standard Operating Procedures |
A state of consensus among the operating personnel on the
documented methods for the operation of a process |
| Reliability Methods |
Prevent process failures that result in product failures |
The goal of process control technologies is to eliminate
nonconformances and minimize variation at the lowest total cost.
