Learning MEDDIC from the actual source: This is the first book ever written on MEDDIC, by Darius Lahoutifard, one of the early sales leaders at PTC where MEDDIC was invented and sponsored by Steve Walske, the former CEO of PTC, the one who took PTC from zero to $B1 in 10 years. This is a must-read.
