If your organization has invested substantially in smartphones running on the BlackBerry or ActiveSync mobile platforms, you're likely under pressure to achieve economies of scale while maintaining a high quality of service. But before you can wring costs out of your mobile platform, you must understand its actual Return on Investment (ROI) and Total Cost of Ownership (TCO). This handbook is designed to help senior IT management calculate their organization's mobile ROI and TCO -- using an enterprise environment of 2,000 mobile users to demonstrate the approach -- and includes a 5-step analytical approach for reducing that TCO by as much as 15-20 percent.
