We hear about disruptive technologies and live in a VUCA world (Volatile, Uncertain, Complex, and Ambiguous). New technologies will change business models as they have always done. However the four VUCA factors have varying impacts on business “which defies confident diagnosis and befuddles executives” (Bennett & Lemoine, 2014).They identify four potent weapons to fight digitalisation dragons: agility, information, restructuring, and experimentation.This blog compares earlier waves of technology with the digitalisation wave. Currently, 40–60 percent of customer value is not created within the focal company but in the supply chain (KPMG, 2016). The same holds for the purchasing-turnover ratio: 20 to 85 cents of every euro sold was purchased from suppliers (Van Weele et al., 2017, p. 35). In current business models B2B sales and procurement play dominant roles.The blog (Part I & II) discusses the impact of disruptive technology on business models with a focus on procurement (purchasing).
