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
Research rationale Implementation gap Especially in strategic planning Constructive learning requires:
Consolidated aims Consolidated theory Consolidated methods
(Nijstad 2009 in: Te Brömmelstroet 2013)
Conceptual model
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

RESULTS ON PLANNING PROCESS QUALITY
RESULTS ON PLANNING OUTCOME QUALITY
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)
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
