What is group modeling

What is Group Modeling?

  • A form of group decision support, involving a group of stakeholders with a complex problem

    • Group facilitation

    • Model building and refinement in public

    • Simulation of scenarios and options

    • Extensive facilitated discussion and analysis

    • Facilitated policy design and decisions

What is group modeling1

What is Group Modeling?

  • Management team (10-20) with a Modeling/Facilitation team (2-4)

  • Four full days over 3-to-4 months

  • Extensive between meeting work

  • Rapid prototyping of model with finished simulation product

  • Facilitation of implementation plans

Introduction to simulation

Introduction to Simulation

  • Concept models

    • Introduce the stock, flow, and causal link icons used throughout the workshop

    • Demonstrate there are links between feedback structure and dynamic behavior

    • Initiate discussion about the structure and behavior of the real system

  • Less than 30 minutes

Concept model progression models are ours to change and improve

Concept Model Progression:“Models are ours to change and improve.”

Concept model progression behavior is a consequence of structure

Concept Model Progression:“Behavior is a Consequence of Structure”

Client flows in the resulting tanf model

Client Flows in the Resulting TANF Model

Client flows in the safety net

Client Flows in the “Safety Net”

Confidence building processes

Confidence building processes

  • Structure of the model emerging from group process

  • Parameters based on administrative data everywhere possible

  • Parameter and table function group elicitations

  • Group contributions to tests of model behavior

Simulated vs actual caseload

Three policy mixes

Three Policy Mixes

  • Base run (for comparison)

    • Flat unemployment rate

    • Historical client behaviors

  • Investments in the “Middle”

    • Additional services to TANF families

    • Increased TANF assessment & monitoring

    • Safety net assessment & job services

  • Investments on the “Edges”

    • Prevention

    • Child support enforcement

    • Self-sufficiency promotion

Emerging lessons

Emerging Lessons

  • Unemployment dominates system performance

  • Loss of eligibility will shift the next economic cycle’s costs and caseloads

  • Endogenous management makes a smaller difference

  • Employment programs at the middle of the system are low leverage points

  • Policies at the edges of the system have high leverage

  • Community-wide partnerships are needed to implement “Edge” policies

  • Performance measures continue to be problematic

Resource allocation unpacking the policy resources for implementation

Resource allocation: Unpacking the Policy Resources for Implementation

  • 43 participants about 30 agencies and organizations in the county

  • Three stage process

    • 9 groups

    • 6 larger groups

    • 3 final groups

  • Ending with five initiatives, costing about $675,000

Final proposals implemented in cortland

Final proposals implemented in Cortland

  • Job center ($150K)

    • Centralized location for all referrals

  • Resource center ($150K)

    • Coordination of community effort toward diversion

  • Program to support employed self-sufficiency ($200K)

    • Job counselors, case managers, private sector

  • Computer-based comprehensive assistance ($150K)

    • Link all providers and case managers, shared database

  • Expansion of child-care services ($75K)

What are we really doing

What are we really doing?

  • Microworlds?

    • Data-based representations of a policy reality

    • Tools for finding what options really work best to solve a complex dynamic problem

  • Boundary objects?

    • Socially constructed representations of a negotiated world that may not exist

    • Tools for facilitating discussion and agreement in contentious environments
