- 36. 36 Model Creation Recommendations 3) Climax 1. Relation with reality ü Use the zone of proximal development between the modeler and the readers’ conceptualizations to show concreteness using photos, icons and terminology that characterize actors 2. Rationale ü Show the main question, the options, the criteria and the assessments of criteria ü Use “satisficing” to model options that do not fully satisfy criteria ü Use “accommodation” to model conflicting interests and consensus 3. Story ü Create model instances for each story phase, e.g., context, conflict, climax and closure ü For each model instance explore the actors’ states to show change

- 45. 45 ü We created improved SEAM models based on interviewing 200 readers ü This research is inter-disciplinary: systems thinking, graphical argumentation, interpretation of reality, learning, and story-telling ü The originality of the research lies in understanding the readers’ conceptualizations in order to create improved models ü Instead of multiple different models of the same situation, we propose one model that illustrates a story 4) Closure Conclusions
- 46. 46 v Modelers can apply our recommendations to v Model other contexts (e.g., organizational strategy, service design, enterprise architecture) v Model other hierarchical levels and refinements with SEAM (e.g., service specification and implementation with business / IT services and processes) v Improve models created with other notations 4) Closure Future Work UML BPMN ArchiMate
