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. The platform is designed not just for enterprise visibility but for true end-to-end coordination across extended supply chain ecosystems.

At the Gartner Supply Chain Planning Summit in Denver, Scott Luton sat down with Nari Viswanathan, a veteran innovator in the planning and procurement technology space and a key leader at Coupa.

Direct spend, of course, is where supply chain operations come into focus, making planning, design, and cost optimization central to the value Coupa delivers. Viswanathan leads Coupa’s global supply chain strategy, shaping how the company positions and scales its solutions across the market. After years spent in supply chain planning technology, he now sits at the intersection of procurement, supply chain, and advanced analytics—an area he believes has never been more exciting or more critical.   Old Problems, New Pressures—and a Greater Willingness to Innovate When asked about the biggest challenges facing planners today, Viswanathan emphasized a…
