There is a growing interest and focus on Process and Service modeling. There is also an uncertainty on using the correct modeling conventions.
Now you have a newly released Modeling Convention in the form of the SAP Modeling Handbook Wiki. http://wiki.sdn.sap.com/wiki/x/3wh8C
This Modeling Handbook is meant as a general guideline for anyone who does work on either Process Modeling or Service Modeling.
The guidelines, rules and model structures are based on experiences gained within SAP Field Service and Support and were developed by consultants. The Handbook is not tied to a special methodology (implementation or other) although the structure applies to the rules of ASAP Methodology.
We specifically chose to present the Handbook in the format of a wiki because we value your contribution and feedback.
We are confident that this SAP Modeling Handbook will remove some of the current uncertainty which exists around process and service modeling.
