When you think of process control, what usually comes to mind is some form of technology (e.g. automation, robotics, an app, etc.). However, even with the most advanced computer controls, many processes still fail to achieve the desired output. And often, manufacturers may find processes that seem to work well at times but seemingly fail for no good reason at others.
Most organisations will then conclude that it must be their people causing these failures. And that with more experienced or better-trained employees, the problems would go away. What they don’t account for, however, is the process variations can affect the end result.
