What are Process Characteristics

Process characteristics

Can someone pls. give me some examples of process characteristics ? Can operator skill be a process characteristic? If so , what can be the control method?
Can we consider any of the 5M's as process characteristics?

Are you referring to characteristics on control plans?

Here are a few examples:

Clean line or oven temperature
Speeds & feed rates
Pressure or other equipment settings

I believe that operator skill should be a requirement, but wouldn't be considered a process characteristic. Some of the 5Ms would be process characteristics - look at the examples I gave above.

I would say that proper training could be a process characteristic. It is hard to get out of the mode that characteristics are solely dimensional.

I this case a control method might be ongoing testing to the standards and training provided to keep people up to date on current process requirements.

Al,

Do you mean competence qualification (as mentioned in ISO 9001-2000)?

We all call it what we want, but as an old timer I call it initial and ongoing training.

I still need more convincing before I could really believe that training is a characteristic and not an item that needs to be in place before the process is finalized. Can we assume in a process that we must rely on the thought that the previous step is labelled as effective?
