Just come across an article about SAP and Capgemini's partnership on developing a Direct Store Delivery mobile application in the next five years.

This is part of the plan of SAP to provides hundreds and thousands of mobile applications for users, most of which are planned to be developed by partners.

As we all know, SAP has release Retail Execution Mobile Application. This application provides basic and general functions of data collection and store visits for merchandiser or sales people in retail and consumer products industries. It is simple and easy to use, however, it is far from the expectations of this industries users as it cannot fully provide end-to-end solution for roles other than merchandisers in the supply chain, for example, inventory management, delivery, etc.

This future killer app of Mobile Sales Execution together with Retail Execution App will change the way which the current store delivery operations are doing. From order to invoice, from route to transportation, from warehouse to stock, from reload to unload, from visits to audits, from master data to reporting, from barcode scanning to GPS locations, the information are all in one killer app. The brand new app will connect with backend ERP and CRM via Sybase Unwired Platform which is the SAP heavily invested mobile infrastructure.

What I think is the SAP and Capgemini do need to leverage strengths of each other to build this app. Five years seems so long, but it deserves to wait.
