Question to the Department of Health and Social Care:
To ask the Secretary of State for Health and Social Care, what recent steps he has taken to improve software quality in the NHS Test and Trace system; and if he will make a statement.
The NHS Test and Trace software quality is appropriate for its use as it is based on historically proven Public Health England and National Health Service software. The challenges have been around scaling as the volume of positive test results increased exponentially. The priority initiatives have therefore focused on improving data quality; making technology infrastructure improvements to allow faster test results and faster contact tracing; and moving away from legacy architecture that was not designed for this purpose.
