The U.K. was in the grip of the unprecedented global COVID-19 crisis. NHS Digital needed to create a robust COVID-19 national testing programme that could scale rapidly and with no room for error.

Deloitte Digital built and ran a suite of 10 apps deployed on 12,000 centrally managed iPhones that allowed staff to check people in for appointments, process test samples, track samples en route to labs and then allowed lab staff to prioritise their workflow. This removed paper-based workflows, minimising errors, and making it possible to launch as many as 45 new test sites a week with minimal training. Test numbers immediately rose from c.5,000 a day to over 45,000 (now over 500,000) and the number of people receiving their result the next day rose from 14% to 74% in a month.
