Our Windows Mobile team has just created an on-line tool to provide you help in building a business case around deploying Windows Mobile for all types of applications.
It's called the Windows Mobile Business Value Calculator.
It gives you immediate visibility into the impact of deploying mobile business solutions on the Windows Mobile platform. Using a company's unique information, such as number of mobile workers or types of applications to be mobilized, and summary data from IDC, the Business Value Calculator allows you to quantify the benefits and the direct and indirect costs of deploying mobile line-of-business applications, including measurable impact on revenue and income, operating expense savings, productivity enhancements, and other strategic business improvements.
So if you are in the early phases of a mobile project this could be quite a helpful online tool.
