2. Standardize. Many global companies have SAP installations that were not necessarily implemented in a coordinated fashion. Take advantage of the upgrade to fix that and standardize as much as possible, Shepherd said.
"Try to find areas where you can get to common business processes, eliminate local customizations and drive back to a standard footprint," he said. "That can dramatically lower the cost of managing the system."
3. Respect cross-cultural differences. When planning an upgrade, get feedback from users on improvements they'd like to see – and do it in a manner familiar to them, noted Jon Reed, an independent SAP analyst and SAP Mentor. Holding a group meeting and asking for feedback may work just fine in North America, but offering suggestions for change may be construed as complaining, which is taboo in some cultures, Reed said. In such instances, organizations need to set up one-on-one time to find out what users really want and need.
4. Conduct a gap analysis. Companies migrating from SAP R/3 to ECC 6.0 may well encounter significant technical differences, such as use of the NetWeaver platform, Java, Unicode and Solution Manager. Conduct a technical gap analysis to determine which technologies to implement off the bat and whether the skills are available in-house to handle them, Reed said.
5. Partner with experts. Reed and Shepherd both advise users to augment internal staff with outside professionals. Shepherd's report noted that -- owing to the maturity and size of the ERP market -- a parallel market has developed of companies dedicated to help implement, manage and upgrade ERP systems.
"There are hundreds of methodologies, sizing analyzers, testing tools, data management utilities, and consulting services proven to deliver excellent ROI investment," Shepherd wrote.
6. Get users on board early. In any SAP update, there will be changes in the functions users employ every day. Rather than spring those changes on users upon rollout, get their input into the process and educate them about changes coming down the pike, Reed said.
"Then when the lights go on and things are slightly different, they'll know why," he said.
