Design Science Introduction

  1. 1. Design Science A Paradigm for Information Systems Research
  2. 2. A Dilemma <ul><li>Rigour </li></ul><ul><ul><li>Exactness </li></ul></ul><ul><ul><li>Precision </li></ul></ul><ul><ul><li>Following rules </li></ul></ul><ul><li>Relevance </li></ul><ul><ul><li>Useful </li></ul></ul><ul><ul><li>Practical </li></ul></ul><ul><ul><li>Timely </li></ul></ul>
  3. 3. Two Research Paradigms <ul><li>Behavioural Science </li></ul><ul><ul><li>develop and verify theories that explain or predict human or organizational behavior </li></ul></ul><ul><li>Design Science </li></ul><ul><ul><li>extend the boundaries of human and organizational capabilities by creating new and innovative artifacts </li></ul></ul>
  4. 4. IS Research Cycle From a presentation by A. Hevner, http://misrc.umn.edu/seminars/slides/2006/12152006_Seminar_Color.pdf
  5. 5. Design is an Artifact <ul><li>Constructs </li></ul><ul><ul><li>Provides the language in which to define problems and solutions </li></ul></ul><ul><li>Models </li></ul><ul><ul><li>Use constructs to represent a real world situation </li></ul></ul><ul><li>Methods </li></ul><ul><ul><li>Provide guidance on how to solve problems </li></ul></ul><ul><li>Instantiations </li></ul><ul><ul><li>Implement constructs, models and methods in a working system </li></ul></ul>
  6. 6. Design is a Process <ul><li>Build </li></ul><ul><ul><li>Construct the artifact </li></ul></ul><ul><li>Evaluate </li></ul><ul><ul><li>Assess the utility of the artifact </li></ul></ul>
  7. 7. Design is a Wicked Problem <ul><ul><li>Unstable Requirements and Constraints </li></ul></ul><ul><ul><li>Complex Interactions among Subcomponents of Problem and resulting Subcomponents of Solution </li></ul></ul><ul><ul><li>Inherent Flexibility to Change Artifacts and Processes </li></ul></ul><ul><ul><li>Dependence on Human Cognitive Abilities - Creativity </li></ul></ul><ul><ul><li>Dependence on Human Social Abilities - Teamwork </li></ul></ul>
  8. 8. Design Science Framework From Hevner et al. ”Design Science in IS Research”, MIS Quarterly, 2004
  9. 9. Design Science Guidelines <ul><li>Design as an Artifact </li></ul><ul><li>Design science research must produce a viable artifact in the form of a construct, a model, a method, or an instantiation </li></ul><ul><li>Problem Relevance </li></ul><ul><li>The objective of design science research is to develop technology based solutions to important and relevant business problems </li></ul>
  10. 10. Design Science Guidelines <ul><li>Design Evaluation </li></ul><ul><li>The utility and quality of a design artifact must be demonstrated via well executed evaluation methods </li></ul><ul><li>Communication of Research </li></ul><ul><li>Design science research must be well presented both to technology oriented and management oriented audiences </li></ul>
  11. 11. Design Science Evaluation From Hevner et al. ”Design Science in IS Research”, MIS Quarterly, 2004
  12. 12. Design Science = Design? From Hevner et al. ”Design Science in IS Research”, MIS Quarterly, 2004 Relevance Cycle Design Cycle Rigor Cycle
  13. 13. An Exercise <ul><li>Identify Challenges to Design Science! </li></ul>
