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 patternsAlexander, 1979

Agreement on findings

Incompletee.g. describing an onlinetraining but leaving out some essential elements

Too abstracte.g. describing an online training only in terms that apply to all web events

Pattern in the world:recurrent structuree.g. the essence ofonline trainings

Agreement on form

Agreement on function

Agreement on aestheticssubjective

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.

Usefulness

General Patterns

Interesting Design Patterns

All recurrent structure

Generative solutions toproblems appropriatefor fitting contexts

Non-trivial, not obviousUsefull and applicable

Thank you!
