Tell Us Once, also called ‘Once Only’, is an approach pioneered in Europe by the likes of Estonia, a policy where having provided your data to one government agency, you’ll never be asked for it again from another, defined explicitly through legislation.
The concept is very simple – Tell one government agency an information update, eg. your change of postal address, and have all agencies receive and action that update.
It would mandate by law the outcome citizens wants from their Digital Government, a simplified user experience that eliminates all unnecessary bureaucracy, without over-prescribing the technical means to achieve it.
“They do so through the “once only” policy, which dictates that no single piece of information should be entered twice. Instead of having to “prepare” a loan application, applicants have their data—income, debt, savings—pulled from elsewhere in the system. There’s nothing to fill out in doctors’ waiting rooms, because physicians can access their patients’ medical histories.”
Estonia achieve this capability by marrying the legislation with the their ‘X-Road‘ system, a national middleware backbone that connects every user to every government application.
