WHy did NHS Test and Trace fail to contact no more than 50% of the persons who tested positive. Why was it not able to followup with the people who needed to be visited in their homes to ensure isolation. Why was NHS associated in the name when the NHS had not been consulted and involved in the design of this service. In fact it ignored lessons from Germany where the contact tracing was entirely from local, started very quickly with the key being local or state employees who were diverted to this task and were skilled and motivated to do it. Why was this critical task simply handed out to outsource it to private companies. 

Germany's example was there very early in March-April and it was working. Why reinvent the wheel. Setup quickly and entirely local it required only a desk, a desktop PC, and a national database to which PC was connected, the skilled caller being the key to getting people to talk to and cooperate. About 80% of those testing positive needed to be contacted. NHS Test and Trace was reaching about 50% and many that needed to be visited at home could not be followed up quickly. The shift is only now being made to go local. It worked in Leicester and other places but the learning came the hard way, as with many things during this pandemic.
