Is there a business phrase for whack-a-mole?

In my company, I've been asked to generate reports about accounts (for example) that have abnormal traits (less than 1%, for example). They want to know where these abnormal cases are so they can go fix them, but it's too time consuming to manually check until they find them. So they asked me to find these cases and report on them.

Some people try to call it exception handling; but exception handling is already a well-define phrase in computing, so it can't be used.

I'm trying to come up with a phrase to describe this type of hunt. Is there a better phrase than "whack-a-mole" or "exception handling"?

Also, I'm new here, so I don't really understand which tags go where. Thank you!

Previously-mentioned anomaly detection is a good suggestion. From en.wiktionary, anomaly means “A deviation from a rule or from what is regarded as normal”, which ought to encompass “accounts that have abnormal traits”.

You might also refer to finding, seeking, looking for, patching, or fixing extreme cases or outliers. From en.wiktionary, outlier means “A person or thing away from others or outside its proper place” in one sense, and “A value in a statistical sample which does not fit a pattern that describes most other data points”, in another. An extreme is something that's most remote, or outermost; or something that's “Excessive, or far beyond the norm”.

Less formally, one can refer to plugging leaks or plugging holes in the dike, and to putting out fires or playing fireman, and to preventive or anticipatory amelioration.

How about using the word spurious? It implies that something is not "normal" and should be investigated further.
