This slide deck was presented at the annual Project management Day (Autumn) hosted in Lviv, Ukraine (November 2018) in the flow dedicated to Product management. It covers specifics of developing and delivering products to enterprise clients, challenges in sales negotiations and pre-sales activities at the early stage interactions with an enterprise prospect, and potential communication traps that product manager might find himself caught in after successful deal closure and delivery start. The deck content is a 'presenting' type, definitely not a 'read-only'. But I hope one may find some interesting insights in it nevertheless.
