I have been appointed Project Manager for a Chatbot project. Which is the best book/web resource for me to read, to get up to speed?

I won’t be coding or anything like that, but will be managing the project on behalf of the international institution that wants the chatbot.

It is a chatbot and not IVR and it will use canned responses rather than AI-generated responses, so it is pretty limited in scope. It will use AI to understand the questions, though.

Thanks for any suggestions!
