Actually, I have worked and run my own businesses (now sold to pursue other things in life). And, some of those were computer manufacturing businesses. And, I did impose a 0 defect rule. And, guess how many repairs I had to perform (0).
Nothing left our company until it was perfect. And, feedback from our customers was 100% positive. Instead of hearing complaints, I got calls all the time from customers wanting to talk about how great their computers were.
It is possible to make money selling perfection. And, it is more profitable than selling imperfection. Because any component with the slightest imperfection was refused and sent back to the manufacturer, I never sold anything that broke down.
Well, I take it back, I did have a few computers that came in for their first and only service repair (they needed a new clock battery after about 5 years). Those, I'd just give them even though they were beyond warranty (after-all, what's a $3 battery).
I've since sold my businesses off. But, you can bet I had quite a track record. Every machine was assembled, tested, and quality checked by a real person. No machine would leave our company until it had been through a 40-hour minimum stress test as a fully assembled machine with a person to constantly monitor and inspect the status of every machine currently being stressed.
If any machine demonstrated the slightest hiccup, it was broken down and every component was individually analyzed to find the faulty part.
Nothing ever left with the slightest issue. No defects. No imperfections. No cosmetic issues.
They all represented the highest quality machines available. And, because I knew they wouldn't fail, I backed them with 100% free support. And, that included on-site in-home or in-office service (though it was never needed).
Our phones only rang for new orders and from customers who wanted to tell us happy stories.
Quality in production is possible. You just have to set those standards and stick to them.
I launched the businesses with a goal and a standard. And, I never lost sight of that. And, it showed in the products my companies sold.
I mean to think realistically, this forum is full of complaining. Every MBP is warped a little, and if it was a lot it would not even change the ability of the MBP. I never thought before i came to this forum that a macbook pro can have so many defects!!! You won't live comfortable being picky.
You can live quite well demanding the best. Settling for inferior quality doesn't improve your quality of life.
There's accepting imperfections in life. And, there's selling yourself short by wasting money on poor quality.
