The way that I think about this issue is that having a wider range of specification is good for many reasons. First of all, it gives a lot of leeway in terms of manufacturing the product and using the product. If there is not a strict limitation into the device, then the errors producing during manufacturing wouldn’t be as frequent as producing a product that must be produced at a set point (e.g. length, width, radius). I think that it’s better to ave a one-sided bound than a two-sided bound because you have more freedom and less stress after the device is introduced to market. If the range is long, then that implies that the consumer will not have a difficult time in using the product because since the specification range is not narrow, then the device should be able to work under more circumstances, such as when it has broken. The specifications should be stretched until the point where the device will no long work if it goes beyond it. The only leeway that you should provide is when you can preserve the functionality of the device.
