Innovation guru Doug Hall says that every business, every product, every service is on a continuum somewhere between Monopoly and Commodity. At one end, you own the market (for the moment) and at the other, you compete with the rest of the commodities. I think it is the difference between Distinction and Extinction. At the Distinction end of the spectrum, sales, margins, profits, market share and brand recognition are all high. At the other end, the opposite is true and when you compete on price, you never win long term. For the record, WalMart does NOT compete on price.* But that's another post for another day.
Innovation is the difference.
Companies that offer true innovation offer unique solutions to customer problems, provide real value, and raise the bar for their industry. Innovation comes in all shapes and sizes. Some are stepping stones to larger innovations. Some (like the mouse, the mp3 player, and the touch screen) go unrealized until someone like Steve Jobs comes along. It's not the size of the innovation that matters, it's the relentless pursuit of innovation and the marketing of that innovation that yields results.
