Transcript

  • 1. (HOW) DO PLANNING SUPPORT SYSTEMS IMPROVE PLANNING? A controlled experiment
  • 2. Urban environments – climate - mobility NWO: CESAR PROGRAM MARCO TE BRÖMMELSTROET UNIVERSITY OF AMSTERDAM PETER PELZER UTRECHT UNIVERSITY RALPH KLERKX TNO SANDER SCHAMINÉE TNO
  • 3. Research rationale  PSS field is maturing  ‘Knowledge technologies’  Many claims & hypotheses  Not much focus on testing  Overview of PSS books:  414 reported claims  59 reported tests
  • 4. Research rationale  Implementation gap  Especially in strategic planning  Constructive learning requires:  Consolidated aims  Consolidated theory  Consolidated methods (Nijstad 2009 in: Te Brömmelstroet 2013)
  • 5. Conceptual model
  • 6. PSS: Urban Strategy  Urban Strategy: developed by TNO since 2006  Started as an environmental modeling tool  Main features:  Calculate and display effects interactively  Centralized data storage  Scenarios  Communication between models

  • 11. RESULTS ON PLANNING PROCESS QUALITY
  • 12. RESULTS ON PLANNING OUTCOME QUALITY
  • 13. Methodological reflection Both observation and indicators show a positive effect on planning (process). But:  Low ecological validity  combine with real world observations  High measurement validity  ‘Quality of planning’ concept under development  External validity  Is Urban Strategy a typical PSS (for strategy making)
  • 14. Methodological reflection Both observation and indicators show a positive effect on planning (process). But:  Role playing is problematic  Students from different backgrounds  Holding treatment constant is problematic  More focus on fundamental mechanisms  Final lesson: Potential improvements on organizing the exchange of knowledge between participants and PSS
