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)
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

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
