Definition

  • Design sciences related to disciplines that build things.

Key elements of design-oriented approaches

(according to Pertti J�rvinen, 2004)

  1. Technological rules
    • tell you how to do things and are dependant on other theories (and beliefs)
    • Bunge (quoted by J�rvinen:99): "A technological rule: an instruction is defined as a chunk of general knowledge, linking an intervention or artifact with a desired outcome or performance in a certain field of application".
  1. Types of outcomes (artifacts, interventions):
    • Constructs (or concept) form the " language " of a domain
    • Models are sets of propositions expressing relationships among constructs
    • Methods are a set of steps to perform a task (guidelines, algorithms)
    • Instantiations are realizations of an artifact in its environment
  1. Types of research:
    • Build: Demonstrate feasibility of an artifact or intervention
    • Evaluate: Development of criteria, and assessment of both artifact building and artifact usage

  • There are 4*2 ways to lead interesting design research.
  • Usually, it's the not the program you build that is interesting, but something behind (constructs, models, methods) or around (usage).
