using intentional and system dynamics modeling to address whys in enterprise (icosft-ea 2013 poster)
DESCRIPTION
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.TRANSCRIPT

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 ofenterprise over time- Steps-1. Derive an Intentional model from EA
Model and i* metamodel mapping2. Manually obtain system dynamics
model using guidelines3. Play out problem scenarios4. Transfer results of dynamic analyses
to intentional models5. Changes in intentional model are
transferred back to EA model
From Intentional models to Systems Dynamics Models and back again
