Does any one has a sample process prioritization matrix for setting-up a control chart?

Thanks..

Is your question about how to choose the right control chart?

If so, google "choosing control charts" and you will find lots of helpful articles and tips.

Thanks you for the reply.

Well the answer is not really. My question is if i have so many processes (all of them newly set-up ,say due to process re-engineering) and i want to put a control chart for each, how do i prioritize? Which process would i want to control first using SPC (given limited resources?)

I have a few ideas like considering criticality, but im not really sure what else to consider..
I tried to google it but no luck.


Thanks in advance!

Reynald,

The way I see it, you could approach this from two directions: one is with some type of plan, or the other would be a random approach. I would much prefer suggesting the planned approached to SPC.

One tool that comes to mind is a Pareto Chart. Ideally, you could categorize all the processes by failures/defects/etc. The top two or three should account for a huge amount of your process variation. Thus, you would focus your efforts on those.

Given that you may have a limitation of analyzing all the processes in a short time, maybe you could categorize processes by impact (or dollar amount, or volume, etc.) and pick the top two or three.

I realize that one would rather get to improving and dispense with the paper chase; that's a natural reaction. However, planning is always so important.

Too, if you pick your projects according to need and impact, a little effort can do a lot to improve the process. You can report this to management, and possibly get more resources for better process control.

If all else fails ask management which processes they would like to see controlled!

Thank you. Yes Pareto would be a very helpful tool.

One question more: on the start of SPC deployment, would you prefer to set-up an attribute chart to be general (like for yield), or a variables chart for specific info? Also would it be better to set up control on the upstream processes (so as to early trap potentials for non-conformances ), or set up the control on the downstream processes (trap later so as to protect the end users)?
