Six years into the smartphone transition, customers are making a mobile mind shift. The shifted customer expects that any desired information or service is available on any appropriate device, in context, at their moment of need. To analyze how far people have shifted, we created the Mobile Mind Shift Index (MMSI), which segments people into six categories: Disconnecteds, Dabblers, Roamers, Adapters, Immersers, and Perpetuals. Companies whose customers have above-average MMSIs and who have more than 35% Adapters, Immersers, and Perpetuals must move urgently to deliver on their customers' mobile expectations. You can use the tools in this report to analyze your own customer base and determine how much to invest, how quickly, in meeting mobile expectations.
