Following the release of SAP's fourth enhancement pack for ERP 6.0, which includes enhancement in core ERP functionality as well as industry specific functionality for the automotive, defense, banking, retail and utilities sectors; SAP emphasized that it will offer more UI enhancements to create more familiarity between the various applications. The UI has been one of the weak points for particular SAP applications in the past (such as CRM and HCM), and at one point became the post-retirement focus of Hasso Plattner.
I had the chance to listen to Bill McDermott recently on the subject, and it seems that the enhancement packs will be increasingly targeted during the down economy to offer more rapid efficiency gains... or as Bill put it several times; to "rifleshoot solutions into your organization..." Despite the odd use of words for directing value to ones customers (please don't shoot me!!!), UI enhancements do seem like good fit for these times, especially for organizations with a broad footprint of SAP solutions and a large/diverse amount of SAP users.
This also helps to add to the list of "pro's" for upgrading to ECC 6.0 during a slow economy for those companies who are not necessarily looking for a large strategic upgrade projects in the short-term, but rather incremental efficiency gains.
