Comments on: Is testing always essential? http://www.embeddedinsights.com/channels/2011/08/24/is-testing-always-essential/ Shedding Light on the Hidden World of Embedded Systems Mon, 28 Jul 2014 16:18:37 -0400 hourly 1 http://wordpress.org/?v=3.0 By: R.A. @ LI http://www.embeddedinsights.com/channels/2011/08/24/is-testing-always-essential/#comment-7760 R.A. @ LI Thu, 25 Aug 2011 19:42:28 +0000 http://www.embeddedinsights.com/channels/?p=620#comment-7760 "...sometimes a product that has not undergone complete testing can still meet all of the performance requirements." Sometimes? I would think that the vast majority of products that have had been previously validated (both the product against user requirements and the production method against the design specification), but haven't been tested would meet performance requirements. Quality cannot be tested into a product, it can only be designed and built into a product. Testing is only a verification that the validated build process has not be inadvertently compromised. “…sometimes a product that has not undergone complete testing can still meet all of the performance requirements.”

CEO's and Presidents don't understand the value of QA and Test. Because it 'doesn't produce anything'. Unless of course the CEO and President could end up in jail for a bad product! That's why Military and Medical fields value QA and Test, while the idiot MBA's don't. What is the price of poor testing and QA? Every release after 1.0 But these bird brains don't get it. Sadly, no.

In a new home, you don't "test" the frame. By constructing the frame according to building codes you ensure the home will withstand the elements. That said, though, you would always test the drain system for leaks! And of course, you would have the house construction inspected at several points. The same is true for electronic systems. You will test a final system, but might not test every component or subassembly before putting the system together. No, testing is not always a necessity. In a new home, you don’t “test” the frame.
