Last week I gave a Forrester webinar on open data in government. The premise was that while big data is changing business, open data is changing the business of government. Open data provides not only greater transparency through access to information. It also improves government decision-making and operations, enables new forms of constituent engagement, facilitates new services delivery, opens new avenues for economic development, and gives rise to new government processes. The presentation explored the evolution of the open data movement, providing examples of the government transformation it has enabled and best practices for launching an open data initiative gleaned from the early adopters.
