We recently discussed our quality performance here and wondered if what we did to measure quality was common and how our results compared with others.
We do have our share of cock-ups!
Would people be prepared to share how they measure quality - particularly the more imaginative, not just numbers of scrap?
Also what is average (mean, SD ) for this industry. Perhaps this might be best done as one of those anonymous questionnaires like gas prices. If there was enthusiasm and a common method of measurement then I would be prepared to analyse the results if Mike Green would anonymize the responses. What do people think?
To kick off:-
We count parts and jobs that have some scrap. We categorise reasons, for instance, bad material, programming faults, machine faults and subcontract faults and show monthly as a graph. Obviously the biggest problems are tackled first (Pareto). The categories are not set in stone and as problem areas are 'solved' the bigger problem areas are split up into separate new categories. This makes improvement continuous and dynamic but means that comparing last year with this is difficult.
We also assign a cost to each failure; made up of cost of the parts, re-doing the job, material, etc. plus an overhead charge of £50 for each NCR. This does give us a base line year on year.
In common with many what we do is controlled to a great extent by our production control software.
So, who does it better and is willing to say so.
