Gartner defines digital experience monitoring (DEM) as the measurement of the availability, performance and quality of the user experience of applications. This can include internal users (employees), external users (customers and partners) or a digital agent connecting to an API. In addition to performance, DEM enables observability of user behavior and journeys based on their interaction with applications. DEM tools allow I&O leaders to understand the availability, performance and reliability of business applications, networks and infrastructure by focusing on understanding the user experience. This is in contrast to other performance monitoring approaches, such as observability platforms, that understand the inner workings of applications.
Tag management system (TMS) simplifies the deployment and management of tags. Tags are snippets of code or tracking pixels embedded in a website or app to collect data and facilitate third-party services. These tags are used for various purposes, including analytics, advertising, marketing, and personalization. TMS allows users to add, edit, and manage tags without directly altering the website's code, often through a user-friendly interface. This helps streamline the process, reduces the need for constant IT involvement, and improves website performance by loading tags asynchronously.
