SAP implementation is the whole of processes that defines a complete method to implement the SAP ERP enterprise resource planning software in an organization. The SAP implementation method described in this entry is a generic method and not a specific implementation method as such. It is based on best practices and case studies from various literature sources and presents a collection of processes and products that make up a complete implementation method to allow any organization to plan and execute the implementation of SAP software.
The implementation of SAP software, such as SAP R/3 is almost always a massive operation that brings a lot of changes in the organization. The whole process can take up to several years. Virtually every person in the organization is involved, whether they are part of the SAP technical support organization (TSO) or the actual end-users of the SAP software. The resulting changes that the implementation of SAP generates are intended to reach high level goals, such as improved communication and increased return on information (as people will work with the same information).
It is therefore very important that the implementation process is planned and executed with the usage of a solid method. There are various SAP implementation methods. An example of how one company, Robert Bosch GmbH, implemented SAP R/3 over 10 years is available. This study shows that designing IT architecture is very critical in SAP implementation practices
