This document discusses the importance of digital experience monitoring (DEM) with continuous performance testing for digital businesses. DEM involves real user monitoring and synthetic monitoring to ensure an optimal customer experience across all digital touchpoints. Continuous performance testing goes beyond traditional testing by occurring throughout the development lifecycle and after deployment to proactively identify and address performance issues. Conducting DEM with continuous performance testing in an ongoing, iterative process is mandatory for digital businesses to guarantee a quality customer experience and prevent business disruptions from poor performance.
