Advances in Group Model Building Reflections on recent work with Colin Eden and Fran Ackermann of Strathclyde University
Outline of Remarks • Part I: Context of the study • The TSA Aviation Security Simulator • The Emerging TPI Approach • Part II: What Happened Last Week? • Logistics • Scripts • Part III: Discussion
Context: TSA Aviation Security Simulator • Contract Between Transportation Security Administration and Argonne National Labs • Argonne, Sandia, and Los Alamos as part of Tri-Labs collaboration • UAlbany as “special teams” subcontractor for Group Model Building • Eden and Ackermann invited to expand team • Some material in this study is SSI
Context: The Emerging TPI Approach • At UAlbany, our work grew out of DTG (with thanks to John Rohrbaugh) • Nearly a decade of cooperative discussions • Joint Seminar at Albany, Humphrey Institute, and Strathclyde University • Recent paper in JPART • Cooperative work with British Health Service in Peebles, Scotland: January 2007
Ancient History: Policy Resources in the Welfare Reform Sessions • Prevention • Child support enforcement • Case management & assessment • TANF services • Employment services, child care, drug treatment, $ • Diversion services • Self-sufficiency promotion • Safety net services • ...all aggregated up from detailed resources...
Education & training slots and referrals for jobs Substance abuse & mental health treatment VESID Workfare and emergency services Job readiness programs DOL & JTPA & private Transportation Federal dollars for training (JTPA) Moneys for grant diversion Transitional Medicaid Licensed day-care and other child care Establish paternity & child support An Example of a Resource Cluster:Employment Services to Families on TANF
Logistics: Plan for the First Half of Day One • Start at 8:00 AM • Initial Issue Identification • Stakeholder Issue Identification • Initial Policy Ranking • BREAK • Graphs Over Time • LUNCH
Logistics: Plan for the Second Half of Day One • Concept Model • Elicitation of Model Structure • Modeler Feedback • BREAK • Scenarios • END at 4:15 PM
Eliciting Model Structure—What we did • “Seed” for elicitation was backbone stock and flow structure from Concept Model as elaborated by group • Used “variable” pack available from “key variable” list made up in the morning • Ability to link model structure to Group Explorer explicitly through variable numbers
Eliciting Model Structure—What we should do next time • Use Stakeholder goals and sanctions exercise to generate feedback kernels and “seeds” • Use Decision Explorer to generate a list of key model variables for inclusion • Experiment with ways to more tightly link DE and Vensim Maps • Explore further “fusion” of methods
Modeler Feedback • A Standard part of our Group Model Building • Completed using ordinary overhead projector
Scenarios • Group Explorer used to begin elicitation of scenarios • Process returned to on second day
Scenario: TSA rapidly create processes to innovate (R=relative impact, G=relative probability across all scenario events)
Discussion • Stages in the Development of TPI • Curiosity (both sides work with facilitated group, computers, and word-and-arrow diagrams) • Cooperative Sharing • Limited Assimilation • Integration (where we are now) • “Fusion” of Approaches: a goal?
What Fusion Might Mean • Duality of Vensim and Decision Explorer Maps • Seamless approach to client groups • Ability to “zoom lenses” between micro and macro views • New support for model formulation and documentation • New products that enhance value to clients • Eventually perhaps integrated software suites
