In the private sectory, productivity has increased by more than 50 percent over the past 25 years, while the public sector hasn't kept pace -- its productivity has actually decreased over the same period of time.

The single most significant contribution to the increase in productivity in the private sector, according to a new report, has been its ability to "harness the disruptive power of technology and to use it [to] invent better and more efficient processes."

The public sector has, in some case, also adopted similar technologies, according to Deloitte's report Gov on the Go: Boosting Public Sector Productivity by Going Mobile, but a productivity gap has emerged between the two — "one widened by government’s inability to dynamically absorb and capitalize on new technologies like we’ve seen in the private sector," the report states.

Mobile technology is a powerful productivity booster —  not only can it improve internal communications and access to information within public agencies, according to the report, but it also enables government to "fully redesign service delivery by leveraging the power of citizens as co-creators."

According to Deloitte's analysis, if mobile adoption rates in the public sector doubled to 70 percent, additional value generated in terms of productivity could exceed $50 billion annually.

Going mobile also enables employees to telework, which is another source of savings for the public sector, as shown by the infographic below. Though this infographic is focused on federal government, similar savings is likely at all levels of government.
