Identifying Acquisition Targets

Hi all, I'm trying to learn more about M&A from a strategic/management consultancy lens (as opposed to a banking/financial one.) Specifically, understanding different strategies and criteria that are implemented in order to identify acquisition targets. Could anyone recommend any resources: books, vids, etc that could be useful for this? Asking for a case competition I'm taking part in with a pretty tight timeline: they just announced the case, which is entirely focused around pursuing a strategic acquisition. 

Thanks in advance!
