A flaw in any design process can be detrimental. It could hold up work to be done for months or even worse, produce wrong results. To prevent this from happening, companies must test their devices repeatedly using different parameters to test every possible scenario. This can be achieved through computer simulations that model the device and incorporate different aspects in each run to ensure that when the device goes out on market, it will not cause any harm. The FDA has strict regulations put in place that forces companies to do so but some companies don’t treat these regulations with seriousness.
