Abstract
Enterprise modeling approaches have been the subject of discussion and development in industry and academia during at least 30 years. Many approaches with different characteristics have been proposed and published; the 4EM method introduced in Chaps. 7–9 of this book is just one of them. This chapter briefly introduces some of these existing EM methods and compares them with 4EM. The purpose of this chapter neither is to provide an exhaustive list of approaches or methods nor to include all possible details and aspects in the comparison of 4EM with other methods. The intention is rather to show that 4EM in many aspects is a typical or exemplary modeling method, i.e., it is easy to switch from 4EM to another method, since many concepts and perspectives used in 4EM also are available in other methods.
