For those that have embarked down the open data road to see where it leads, one thing seems to be clear: Exposing data — whether it is internally within an organization or outside to partners, or even the whole world — is a way of thinking about the very nature of the business, more than it is about achieving a one-off end goal. This is because open data seems to create immediate, close, and powerful relationships between the publisher and the consumer of the data, and leads to a series of unexpected outcomes. These relationships can be created with extreme ease with today’s methods over networks like the Web and though often speculative, a good subset of them form rapidly into important ones that can draw in new customers, identify new innovations, head off competitors, or just generate revenue. Witness Twitter and its hundreds of partners accessing the platform (and its enormous audience) through its API or Netflix and its impressively successful prize contest that opened up data selectively to dozens of high-value self-selected contributors as a leading example.

In other words, in order to be competitive with the next generation of businesses, most organizations are going to have to look at open data for reasons involving efficiency, competitiveness, and long term health, particularly as open data enters their particular industry.
