Boris van Thiel discusses how small incremental improvements, or marginal gains, can provide significant benefits. He outlines how thyssenkrupp achieves marginal gains through innovative technologies like their STAR process for propylene production and urea fertilizer production with elemental sulfur. Process improvements and asset management also provide marginal gains through initiatives like mechanical design changes that reduce energy use by 7%. These many small improvements, though only 1% individually, have large cumulative impacts when implemented across an organization.
