Yeah, but that is a small part of contact tracing (with law changes needed in some countries). The next step is to have personnel to notify suspected contacts, tell them to isolate themselves and then test them.

You need to have enough people for that, you need to have the testing capacity and you need to have people following that order.

It will work well if you have very low community spread and can start tracing on cluster level. If you are not there it can still be a good tool but you would probably still need a lot of other restrictions as well.
