I followed an EMC course last year and heard what good a reliable design can do for a company. A client from our teacher complained that he had to invest 100.000 UK pounds in order to comply to EU EMC directives. That it costed him way too much.
The next year he thanked our teacher for reducing the products returns and waranties by 2.2 million UK pounds. A good design with takes EMC, service and safety into account from the start will pay you back big-time.
You just have to convince your manager that he has to add the extra cost or design time, to prevent a lot of trouble. A big part of the EMC course went about managing your manager, how to design propelry and that you have to think about everything.
Adding remedies (EMC/safety) on a larger scale will multiply the cost of the remedy by a factor 10. Choosing an EMC low noise part costs less than adding a tin-can on your board. The tin can costs less than shielding your entire board. etc. Hardware costs less than production hours.
But you have to produce the first reliable Honda Civic. If your gonna build only 1 of them, the design still has to be reliable. Making a million of Civics only changes your logistics, purchasing, manufacturability and production aspects. You can still design a reliable car. Evne if you only make 1 of them, or even none of them. But then you don't have any prove it works reliably.
30 % more effort on the first stage of design will cut your development time in half. If you get first-time-right, you prevent a second design cycle. You can only aim for first time right when you know what you have to create. If the requirements change or aren't clear, you must create something that let's you find 100 % of those requirements ASAP.
On the other hand, I will fire you when you don't mention that second design cycle in your planning.
If you know what you have to create, design for getting it right 100 % the first time. Always plan (but try your best to prevent it) you will miss the last 5 % and have to go for another cycle. If you aim for 95 %, you will end up at 90 % or lower.
