Using intentional and system dynamics modeling to address whys in enterprise (ICOSFT-EA 2013 Poster)

412 views

Published on

Taking and executing cost effective decisions in enterprises is becoming increasingly difficult due to multiple change drivers that affect varied aspects of enterprise. Enterprise architecture (EA) frameworks provide holistic treatment of whats and hows of enterprise but leave the important question of whys unaddressed. Intentional modeling and system dynamics modeling provide treatment of whys at a point in time and over time respectively. We propose an approach where both intentional and system dynamics models are used in conjunction with EA models for a more effective treatment of whys than provided by either. Our contributions are twofold- first, we provide means to relate EA models with intentional models through a metamodel mapping and second, we provide a set of guidelines to manually arrive at system dynamics models from intentional models. Initial results with a case study suggest that best of both worlds may be obtained with such combined treatment of whys in enterprise.

  1. 1. Using Intentional and System Dynamics Modeling to Address WHYs in Enterprise Architecture Sagar Sunkle, Suman Roychoudhury , and Vinay Kulkarni Tata Consultancy Services, India Analysis of Strategic Vulnerability  Vulnerability in Depender dependee relation  Assurance and Insurance scenarios played out with System Dynamics Models  Together Intentional and System Dynamics Models provide better treatment of whys in Enterprise Encoding and evaluating Whys of enterprise over time- Steps- 1. Derive an Intentional model from EA Model and i* metamodel mapping 2. Manually obtain system dynamics model using guidelines 3. Play out problem scenarios 4. Transfer results of dynamic analyses to intentional models 5. Changes in intentional model are transferred back to EA model From Intentional models to Systems Dynamics Models and back again  Goals and soft-goals -> stocks  Alternative tasks used to achieve goal -> variables  Satisfaction contribution links of soft goals -> inflow and outflow of a stock  Actor dependencies -> Module connectors System Dynamic Models AS-IS Enterprise TO-BE Enterprise Contact me at- sagar.sunkle@tcs.com
