Metrics: what should we measure? (10/25/08)
I am having problems establishing measurable quality objectives for our operation. Might you have any suggestions?
If you are not measuring anything, quality-wise, now, here are some ideas. When establishing performance metrics, it's best to focus on things that impact the customer. All quality measureables fall under three general categories: quality, cost, and time.
- (Cost metric) Cost of poor/deficient quality. What is the cost of reworking bad products, handling products returned from customers, warranty claims, etc. (if this is pertinent to what you do)? Start tracking that, figure out what your "baseline" is (i.e. what the actual cost is now), and then set an objective for improvement (i.e. make the objective less than the baseline).
- (Time metric) Time to resolve customer complaints. How long does it take? Start tracking that, figure out baseline, set objective, etc.
- (Time metric) Adherence to delivery requirements. To what extent do you meet your commitment to customers for when you'll deliver product? Start tracking that, figure out baseline, etc.
- (Quality metric) Percentage of acceptable product delivered. What percentage (in terms of units, batches, etc.) of product is accepted by customer without problems? Start tracking that, figure out baseline, etc.
Objectives: how and where (8/4/08)
Do the objectives of the company have to be approved from top management? Does the auditor during external auditing assure that the stated objectives are being achieved or not? And is it necessary for objectives to be placed for all quality procedures?
Are we doing corrective action correctly? (3/6/08)
I'm MR at a small manufacturing company. Over the past several weeks I've received a number of corrective action requests -- from different people -- that, it seems to me, pertain to the same problem. They all really go back to, we are not monitoring our transportation vendors well enough. Can I bundle all these CARs together into one, and assign it as if it were 1 CAR to someone to handle?
First of all, I applaud you for putting some real thought into the corrective action process. Sometimes people just look at trees instead of stepping back to take a look at the forest.
Absolutely: it is acceptable to bundle these types of CARs together and take care of them with a global process of identifying root cause, corrective action, preventive action, verification, and close-out. By doing it this way you're calling attention to the fact that you're dealing with a systemic problem rather than just a hiccup.
Nice job -- keep up the good work!
Can I poll customers to get customer satisfaction information? (9/28/07)
We do not have any formal means of acquiring customer satisfaction feedback, but we do have conference chat with the customers on weekly basis, and same is recorded. Can this evidence serve as a mechanism to have a customer feedback?
I don't see a problem with this approach as long as you do it consistently, objectively (i.e. don't just talk to the customers who like you), track and trend results, and take action on adverse feedback. Hope this helps.
Benefits of corrective / preventive action? (10/2/06)
What are the benefits from implementing an effective Corrective / Preventive action process into you organization's quality system?
A well implemented corrective action process:
- Prevents process problems from recurring.
- Engages the work force at all levels in improvement.
- Provides a track record for identifying repeat deficiencies.
There are probably more, but these are the major ones in my view.
Monitoring customer satisfaction (11/28/05)
For 8.2.1 Customer Satisfaction, I have been sending customer surveys to different companies at different intervals. My surveys are working with the # system to score from "Very Satisfied to Very Dissatisfied." I am not receiving any of them back and I am wondering what could get our customer to fill out our survey and return them to me. For example, I sent out 31 surveys and only received back 3. Any suggestions? -- Carolyn J.
Surveys need to be very quick, easy, and convenient for the respondent. Oftentimes companies get carried away with surveys and add so many things that people simply discard them.
Here's what we have our clients do. They fax surveys to customers, with a fax-back response. We have them ask customers to respond with their opinion on only three areas:
- Did our product/service meet your requirements?
- Did we deliver the product/service on time?
- Were our people nice to you and easy to deal with?
The customer is asked to rate each of these in one of only three categories: Excellent, Average, Needs improvement. They include a box for comments. Comments, as well as name and company name, are optional.
Responses are analyzed on a numerical basis. Each Excellent gets a 2, each Average gets a 1, and each Needs Improvement gets a 0. Then the results are compiled as a percent of the total possible. And that percentage is tracked over time.
With this scheme, clients have gotten a minimum of 31% response, which is excellent considering the customer gets nothing for replying. (And because the responses come by fax, you have 99% of them within a couple of days.) All "needs improvement" responses get investigated via the corrective action system. Companies set objectives for each of the dimensions (once they know what the baseline is) and report on results at management review. It's not flashy, but it gets good information, and by golly, it works.
"8-D," "7-D," "Corrective Action," what's it all about? (9/8/05)
Companies new to 9001, 14001, 18001, and similar management systems often struggle with the Corrective Action process. This is especially true when they are presented with the typical formats and lists of steps known as 8-D, 7-D, etc.
Here on one piece of paper is an explanation of effective Corrective Action steps lined up beside the typical 8-D list.

How can you see that your CAPAR's are reviewed and addressed in a timly manner?
The only way to be sure that corrective / preventive actions are addressed in a timely manner is to become a professional pest. You have to be organized with ticklers, etc.; get people's commitments as to when processing will be complete; and then pester the dickens out of them. I don't know of any other way to get it done --especially with that segment of management / supervision who are not, shall we say, fully and enthusiastically convinced of the efficacy of ISO 9000 and its various subsystems.
Must every problem be solved?
Regarding 8.5.2 in ISO/TS, our procedure has been audited and found to be in compliance. It does not provide for any incidence of not performing corrective action. For example, some manufacturing problems have no known solution. We have also at times been unable to detect root cause (a part is made wrong for unknown reason). Lastly, unplanned delays have resulted in lost information needed for problem diagnosis. Can we write a clause into our procedure to provide for being unable to perform corrective action?
ISO/TS 16949 (8.5.2) requires that corrective action be carried out appropriate to the effects of the nonconformities encountered. It does not specifically say that all problems must be solved. ISO 9004, the guidance document for ISO 9001 (2000), says, "The organization should balance the investment in the corrective action against the impact of the problem being considered."
That said, you need to show that you have made a good-faith investigation to attempt to determine root causes and potential solutions. If as a result you truly run into a blank wall, or determine that the solution does not make sense from a investment / return standpoint, at least you can show that you have done the research.
If the problems you're talking about are repeaters, adversely affect the customer, and/or cause significant problems for the company processes in terms of quality, cost, or time, you would be expected to invest more time and resources into finding and implementing solutions. In short, it's a balancing act.
