Your Reliability Engineering Professional Development Site
Here’s a question for you: Do you ask your suppliers the right questions concerning reliability?
Probably not.
If you are getting the right information from your suppliers, then you would enjoy few supplier related field issues, or as little downtime or low warranty costs.
Asking the right set of questions will help you gain the understanding you need to improve your reliability performance. [Read more…]
A recent LinkedIn discussion addressed the question of the best strategy for dealing with poor supplier performance.
A lot of the respondents seemed to advocate a punitive approach, either threatening the loss of future business if performance doesn’t improve, or combing through the terms & conditions of the contract for enforcement language.
I’ve always thought that there’s a lot of similarity between managing suppliers and managing subordinates, and I wonder if some of these same people threaten their teams with punitive actions when individual performance doesn’t meet expectations. [Read more…]
Many years ago people would complain about “cheap Japanese” products, but today few people would associate Japanese brands with poor quality.
The turn-around is widely attributed to Deming, and Taguchi, and Juran, and other evangelists who taught not only the tools and processes but also the long-term benefits that can be realized when a company adopts good practices and a culture of quality.
Today I hear people complaining about poor quality in Chinese-made parts and products, and there have been several widely-publicized incidents (see Aston-Martin and counterfeit parts).
Many customers have decided to move their production and seek part suppliers in other locations, including “re-shoring” to North America, in part because they’ve concluded that any cost savings due to cheaper labor are outweighed by the costs of poor quality.
It’s hard to say whether this will have a negative impact on the worldwide consumer perception of Chinese brands such as Lenovo, Haier, and others.
Suppliers often include reliability information along with performance specifications.
We look for reliability statements as one part of the selection process to ascertain if the component is likely to have sufficient reliability.
When the vendor’s data is clearly stated and meaningful, that information saves us from potentially having to conduct our own reliability evaluations. [Read more…]
It was late Friday afternoon and the phone rang. Which is rarely a good thing.
There seems to a significant spike in field failures due to one component. The initial failure analysis work reveals the issue started with a batch of parts received about two months ago and the flaw continues to appear in subsequent batches. [Read more…]
It’s Friday afternoon and the phone rings. It is another customer complaining about your product not working. This is the fifth call this afternoon. Something is wrong and you’re responsible for making it right.
The natural failure analysis process starts across your team. Gather information, determine the scope of the issue, work to understand the root causes, and implement an appropriate solution. This may involve stopping production, halting shipments, or even a product recall.
Initially, you just have more irate customer calls than a typical Friday afternoon. [Read more…]
