Process improvement is moving fast, and the economics are showing up clearly. For example, the U.S. cost of poor quality is estimated at about $2.7 trillion each year, roughly 12% of GDP, which makes the case for fixing process waste more urgent than ever. At the same time, automation coverage across core back office processes is at 45% for 2024, leaving a wide gap between what teams are measuring and what they are actually automating.
