Human Factors
On approach we were advised by ATC of a low level alert. At the time we were on a visual approach and trying to maintain a safe distance behind traffic ahead. We allowed ourselves to get one dot low on the glide slope at approximately 1500 ft MSL. We immediately leveled off and captured the glideslope for remainder of approach. Being more situationally aware and better use of the automation on board the aircraft to [mitigate] increased work load. Late change to arrival and runway due to our request because of winds other than originally planned.
Widebody air carrier Captain reported ATC issued a low altitude alert during an ILS approach when they inadvertently descended below the glide slope.
