CA Customer Experience Manager (CA CEM) is a product within the Application Performance Management solution that measures web application performance for each individual customer. CA CEM measures the performance and quality of customer transactions, identifies defects and variance, and quantifies the impact on customers and the business. CA CEM lets you monitor real user activities -- including login, account update, or purchase transactions -- at the business service level. By proactively detecting trends in degraded customer transaction response times and providing various actionable reports, CA CEM lets you act before problems occur or SLAs are out of compliance. These capabilities enable both your business managers and IT staff to understand and resolve performance problems before end users call for support.
