Wait or not wait? MSA (Measurement System Analysis) Actions

[Black arrow]

Hello,

My experience of MSA studies are that they are time consuming, it takes time to plan, execute the study and analysing the result and probably make the study several times after the first one.

One scenario could be that you improve % Tolerance from unacceptable to acceptable during several msa studies after been improving several contributions to the result.


Here comes the question.
Do you act immitidetly after the first msa study e.g. decrease sorting limits or do you wait for actions before you have made several msa studies....

I'm sorry but I don't understand your question (what are 'sorting limits?) - can explain with more detail with a specific example?

Same question as Bev, but I'll make a more general statement:

Changing how you do something takes a bit of work. Procedures to be updated, retraining, etc.
I often find that it is better to wait until I know I'm changing to a 'known good' and change only once, rather than to make six incremental changes.

Much of this depends on the magnitude of the change, and how that change may affect your customers. If your customer wants improvement NOW, changing to "better" now may be the best choice...then changing to "known good" when your improvement work is done.

If it is just an internal improvement, perhaps changing just once is the best choice.
