There are numerous published comparisons of the approaches used by different countries such as this recent one www.nature.com/articles/d41586-020-03518-4
and an older one here www.theguardian.com/world/2020/sep/18/covid-test-and-trace-uk-compare-other-countries-south-korea-germany
It is vital to spot outbreaks while they are relatively contained and rapidly apply effective local isolation to prevent them growing. From memory this has often been mentioned for China and S Korea. Once outbreaks become large no track and trace system will work because it is overwhelmed. That is when a wider and severe lockdown is needed to bring numbers down to a level where the system can cope again.
We had that window for several months this summer but did little to make use of the opportunity. Our national system seems to lack the capability of successful locally-based schemes to rigorously enforce isolation after identifying cases and their contacts. To put it crudely, somebody knocking on your door and laying down the law. Also of course providing adequate support for those told to isolate.
