13. Research Methods
Inductive Approaches:
•Personal Retrospection: Individual contributions
•Sociological: Interviewing others
•Mining workshops: Community contributions
•Artifactual: Observe and analyze
Kerth und Cunningham, 1997; DeLano, 1998
Deductive Approaches:
•By pure argument: Derive new patterns
•Experimental: Testing existing patterns
Alexander, 1979

15. Confidence
0: Just a theory. A proposed solution structure.
1: Just a design. An actual solution structure.
2: A re-tested design. Maybe just coincidence?
3: A recurrent design. A Pattern.
