For a quick catch-up on examples of how data standards can produce immediate and repeated savings in government, take a look at Gene Dodaro, Comptroller General of GAO, testifying to the House in April 2014.
Dodaro gets straight into how the Department of Defense has a separate system for each of its satellites and could save a fortune by standardizing. He also notes how joining up data across the federal government can increase revenues. For example, passport applications could be withheld for people who are delinquent in their taxes. Identifying overlap, fragmentation, and duplication is time-consuming but not too hard – an external perspective is usually enough. Quantifying the losses due to such inefficiencies can be harder. But pinpointing and applying the solution – standards – is relatively easy. With the scales of operation at play in government, the business case for standards is always going to be overwhelmingly positive.
I like Dodaro's rolling hit-list approach to fixing these deficiencies in government operations. He's like a project manager with an issues log and a very strong sense of purpose. US Government
