"Cisco calculated the IoE Value at Stake for the public sector by taking a bottom-up approach considering the value created by 40 use cases — both agency-specific and cross-agency. Top-down analysis was also performed as a cross-check to validate the completeness and order of magnitude of the more thorough bottom-up approach. Finally, care was taken not to double-count value across use cases.
"IoE Value at Stake is based on net value: for each use case, we considered both the connections benefits
and costs. Our use cases reflect the projected result of the application of technology — in this case, public-sector transformation driven by the Internet of Everything. Cisco's Value at Stake calculation encompasses both agency-specific and cross-agency use cases."
