Great article - it just takes getting management to buy in so that it becomes corporate culture in a world where speed to market is often an overriding factor. If you can prove this:
"Catching errors early will save 10 to 1,000 times the money to solve. Due diligence ahead of time is key."
I worked for a company were we did company-wide QIT training. It focused on doing things right the first time and this certainly falls within that paradigm. While initially we had more expenditure and time costs, it did prove that in the long run it saved money and increased the profit margin as a result.
Cabe, regarding your main point, getting the pre-design requirements and specification right BEFORE Design & Build efforts are launched, I only say 'Amen'. This seems like an obvious thing, but most times is still missed because of complexities stretching the hard-line schedule. How many times have we heard the Program Manger direct that "we're slipping – we can address that later",,,,
On the lesser point of testing due-diligence, of you have precisely defined the point of diminishing returns in micro-miniaturization. When discrete components continue to reduce in size, beyond the ability to probe with the point of a needle, design layouts naturally make the micro-leap to SoC's as you pointed out. But testing proper functionality of SoC's (to achieve the desired result is either a theoretical analysis, or an empirical effort requiring actual 'build & sample' efforts.
Cabe, great article as always. I focused on the beginning of your article. It mentioned soldering. I know i't wasn't the point of the piece, but it reminded me of something. Now this was told to me by a friend so don't quote me...lol... but...a lot of the xbox360's failed due to a red ring of death..which I was told was due to "bad" solder that wouldn't withstand the heat of the unit. I do not recall MS ever admitting to this, but they did come out with a new unit which did not suffer this fault. Finding problems is the first step, admitting them the second, actually fixing them the third and most important. I know the engineers know this, but I don't think the companies care so much. It's all about money to them. Just a thought.
Cabe, I had one more thought one this. Now I could understand if I bought a cheap thing from wherever and it failed. Ok, I bought a cheap piece of junk. I get that. It is when the best still fail that gets me. I mean you think you are buying (paying) for the best, and it still fails? They need to have better quality control. Isn't that expected from the best? Just my opinion.
Hey Cabe....nothing to do with the article, but wanted your opinion if you have time. Do line conditioners for audio work? Never tried one, but I think I need one. I have hiss that I want rid of...just wondering if a line conditioner will remove it. Thanks.
This is not an isolated incident. It plagues my house. Every room. It does not effect my laptop though. That could be because of the power source though. Just trying to figure this out, anyone with an idea.....let me know and thank you!
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
