Quality or Quantity?

[PornoDoggy]

What examples can you think of that do either best? ie McDonalds is a classic 'quantity' business that lacks 'quality'. GM is quantity, BMW is quality etc.

QM has both quantity models (Chevy Cavilier) and quality models (Cadillac).

I think it's difficult for an entrepeneur or a start-up to offer both ... but as a business matures it usually evolves to a point where it can (in fact, needs to) offer both. There are exceptions (the Dollar General/Family Dollar stores, like McDonalds, come to mind immediately), but as a rule that's the path most seem to take.
