I would think the economics of this are very clear. Sending bad products out the door will cost more in the long run than fixes would cost. Given that, this story is probably one of line managers rather than executives. This decisions was probably made to meet a quota, and those directly involved were probably hoping those at the top wouldn't notice anything except that the quota was met.
In today's world of tweets and Facebook chatter, companies--be they consumer focused or industrial--can really pay the price for letting faulty products out the door. Rob is right--there's a huge price to pay for that, both financially and in taking a hit on your brand reputation. But I have to agree with the others that the bigger lesson for engineering is getting the product right the first time.
"Either a notification when the order is placed (a red flag in the manufacturer's order entry system to let the buyer know), or how about a warning label on the box, or an insert with the installation instructions?"
In semiconductor products (ICs, memory, ASICs, etc.), the customary practice is to indicate on the product's data sheet (online web page), and on all summary and selector guides, the phrase "Not recommended for new designs." That tells it all, without having to indicate that a part doesn't behave as expected. The savvy engineer either avoids the part or inquires about the fault.
Insert that phrase into your favorite search engine to see how widely it is used.
It's amazing that they let it get this far. Knowing that this is the attitude of that particular company, I wonder if the engineers will continue to specificy its products in the future. And if word starts getting out about that company's name....
Rob, I think you're right. There have been tons of studies done that demonstrate and verify this simple principle: people complain to each other about lousy products and bad service. Even more important, trying to reverse the effects of bad press, deserved or not, is not only nearly impossible but can backfire. It's mind-boggling that these messages don't seem to have been driven home for some companies.
On a purely economic view, I can't imagine the practice of letting faulty products out the door can do anything by hurt the company's bottom line. There's the potential of costs in returns and repair, but the biggest cost may be in goodwill. As you can see from Made by Monkeys postings as well as the discussion boards, a customer who gets a bad product will talk to a lot of customers and potential customers. That's gotta cost.
Certification and re-certification are issues for both safety products and military products. Getting things certified for use by the military is also a gigantic pain and re-certification even more so, and all of it, of course, costly. Yet suppliers to the military know this, and if that's what it takes, that's what they do. Why should consumers have it so much worse than soldiers, and be subjected to manufacturers who can't be bothered with a certification process?
I will gladly pay somewhat more for better quality. But I find it increasingly difficult to find those better quality products.
This article demonstrates the importance of getting it right the first time. TJ is absolutely right that the company's handling of this issue was inadequate. But if the company hadn't let a defective product out the door in the first place, they wouldn't even be in the awkward situation of having to respond to a problem like this. Nobody's perfect, but attention to detail upfront can prevent a lot of heartbreak down the road.
This story brings out a point that most folks are not aware of, which is the paperwork and testing that are needed for a product to be a "certified safety product". It was undoubtedly the paperwork and recertification required with any change that made them refuse to correct the problem.
Now we see ads describing how wonderful it will be when the safety system is a integral part of the control system. BUT, consider what happens if the system gets into the field and a problem anywhere is discovered. Fixes would be less likely because any change woulr require a re-certification, which costs money. Keeping the safety system separate may be less convenient, but it is the best way to avoid that sort of problems.
TJ, thanks for writing this article. As a consumer, I can't count the number of junky products I've bought unknowingly--way more in recent years it seems--with no recourse because their defects didn't cause safety or health problems. In many cases, thought, it was a similar situation. Your key phrase, I think, is "Why then, did the manufacturer continue to sell (and still sell) a product with a known defect?" And also, the fact that there was no warning. Of course, a warning would dissuade a lot of people from buying it. Your other key phrase is "But how many engineers have the time to search technical support Websites for potential defects of all the components in a design before you place the order?" Exactly. That's what quality practices were supposed to be about.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
