Mobile isn't just a consumer phenomenon; infrastructure and operations (I&O) leaders and companies that fall short on meeting employee mobility needs miss out on a fundamental opportunity to better serve customers, support employee productivity, and ultimately, grow revenues. This report showcases Forrester's Employee Mobile Mind Shift Index (eMMSI), an analysis of worker mobile intensity, expectations, and behaviors. Insights from this index can determine how urgent it is to provide certain employees with mobile devices, applications, and content; what their expectations are; and which features to include. This is an update of a previously published report; Forrester reviews and revises it periodically for continued relevance and accuracy. We're updating it now with new data and insights from the Forrester Data Global Business Technographics® Telecommunications And Mobility Workforce Survey, 2016.
