What you're asking is a bottom-up approach and I'm not sure if it can help you in this context. What you may get in return is a bunch of theoretical concepts that may or may be relevant to your case.

Try to find answer using top-down questioning. Perhaps ask questions to the party that gave you this feedback (Ask yourself first), Was I too slow? Did I miss out on an important context? What other specific thing was noticed?
