At the 2025 Gartner Supply Chain Planning Summit in Denver, Scott Luton met with John Lash, who leads strategy and vision at e2open, a WiseTech Global Group company. E2open is a global platform powering the entire lifecycle of making, moving, and selling goods, with capabilities spanning planning, logistics, global trade, supply management, and procurement.

From supply planning disruptions to last-minute schedule changes, firefighting remains a daily reality. “Life happens,” Ozdag noted. Plans rarely match reality, and organizations must constantly adjust. But today, a new layer has been added: AI uncertainty.
