Almost any mainstream business metric. Here is a brief and incomplete sample: Revenue, net income, employee head count, customer satisfaction, customer retention, customer lifetime value, return on invested capital, end price reduction for customers, stock price and market capitalization, SKUs available for sale, new products/services launched, etc etc.
By those metrics, IKEA fits the bill as well. But at what point do we qualify productivity with some measure of quality? You'd be hard pressed to argue IKEA produces quality . For all the laurels and new features and gadgets and gizmos have produced, very few AWS offerings or new Amazon products are considered best in class.
IKEA makes cheap, good enough furniture. Similar to Amazon's approach. You can't argue that either is not hitting a certain high quality bar when neither are striving for it.
