11 Conclusions BPM - #61 - PG 06 BPM - #62 - PG 06 Business process ing Many approaches to process ing Practice often based on (rmal) petri net variants but quite some confusion Integration required of organization, rmation, and process Multi-level and/or multi-aspect ing required for complex applications Advanced aspects required for complex applications (but adopted by practice?) Business process enactment Workflow management integrates aspects of classical control cycle Workflow management not yet as generally accepted as base management Standardization lags behind Choice between structured (MS), semistructured (CHS) and unstructured (GW) Heavily influenced by emerging Web standards (e.g. BPEL) BPM - #63 - PG 06 BPM - #64 - PG 06 11
