I'm trying to describe a process that, though intended to be fully automated, instead required human intervention in a particular instance, owing to unspecified difficulties with the process. I'm looking for a single word to replace X in this sentence:
This meeting is to discuss X processes.
where the sense of the sentence is
This meeting is to discuss processes that required intervention.
I also want to avoid anything that has significant negative connotations. For example, bungled might be accurate, but wouldn't work in this case.
What is a single-word alternative to the phrase "that required intervention"?
