Purpose of the paper


Starting an enterprise-wide SAP BW implementation requires strategic planning. This paper outlines the most important steps that should be followed when creating an SAP BW strategy. It describes conceptual considerations. It is targeted for project leaders for large SAP BW projects/ and decision makersthat are involved in creating strategies for the implementation of enterprise wide or global implementations involving SAP BW.

What is an Information Model?


1 Enterprise-wide Business Information Requirements and data structures


One important deliverable of the SAP BW strategy will be what we call an integrated information model. The information model is the foundation for a successfulrollout of enterprise wide integrated analytical applications.

Process engineering projects focused on efficiency of processes, sometimes forgetting what kind of people are involved and how the people can effectively measure the effectiveness of the processes in order to continuously improve them. Information modeling (The process of creating the Information modeling) puts people in focus. Itlooks at how people are using information to fulfill their roles within an enterprise.

One dimension of the Information model is the documentation of business strategies and objectives, the main processes (value chains) , and the main players (people and roles) controlling the process, the information needed for the players to monitor the processes. The results of the analysis are then documentedwith performance indicators (measures that measure either processes or strategies/goals or satisfy legal requirements) and the main objects (dimensions) of the performance indicators.

The business requirements then should be summarized in a data model and the definition of global (enterprise-wide) data requirements. The enterprise-wide requirements are a framework for the SAP BW roll-out andmust be considered when implementing SAP BW solutions for smaller units of the company. The other dimension is the Information Supply Chain.

Another area where Information modeling focuses is the information management process. The information model is a logical design model and explains, how to structure information, where and how to gather...
