Mobile Enterprise Application Platform (MEAP)Rule of Three (Gartner)

MEAP offers significant advantages:

•

When there are 3 or more mobile applications

• When there are 3 or more targeted operating systems or platforms

•

When they involve the integration of 3 or more back-end systems

Example

• SAP Productivity Apps, e.g.:

• SAP Timesheet

• SAP ERP Quality Issue
