Business to IT Transformations Revisited Sebastian Stein 1 Stefan Kühne 2 Konstantin Ivanov 1 1 IDS Scheer AG, Saarbrücken, Germany 2 Business Information Systems, University of Leipzig, Germany 1st International Workshop on Model-Driven Engineering for Business Process Management (MDE4BPM 2008) Stefan Kühne (UniLeipzig) Business to IT Transformations Revisited MDE4BPM 2008 1 / 20

  2. The semantic gap Semantic gap between business requirements expressed in a business process modelling language (BPML) . . . . . . and technical implementation expressed in an executable process language Stefan Kühne (UniLeipzig) Business to IT Transformations Revisited MDE4BPM 2008 2 / 20

  3. The semantic gap Manual mapping vs. automatic transformation error-prone, time-consuming, cost-intensive . . . Stefan Kühne (UniLeipzig) Business to IT Transformations Revisited MDE4BPM 2008 2 / 20

  4. The semantic gap Manual mapping vs. automatic transformation error-prone, time-consuming, cost-intensive . . . . . . synchronism, unified implementation strategy, platform independence, separation of jobs, Stefan Kühne (UniLeipzig) Business to IT Transformations Revisited MDE4BPM 2008 2 / 20
