The research process
Types of contributions
• Constructs: Vocabulary for an IT-related domain.
• Models: Description of phenomena using the vocabulary.
• Instantiations: Working systems that are used as proof-of-concept to illustrate that produced constructs, models and methods are useful.
• Methods: Processes and steps to follow in order to solve problems in the domain.

Research, not Development
• If you make some IT-related artefact, how do you make sure you are doing research and not only development?
Big decision to make
• What is the role of the IT system in my research?– The main focus of the research
• E.g. a novel online Pizza order application.• Research domain: Computer science.
– A vehicle for something else• E.g. learning about pizza eating habits of a population.• Research domain: Information systems
– A tangible outcome of a process, where the process is my focus• E.g. learning about how good agile methods are for developing this kind
of applications.• Research domain: (Empirical) software engineering
• In any case: if you build a system, you need to document the process and what you learned from it.
Types of research activities
Types of research activities: Example
• ProperPizza.com– Build: Create a novel user
interface concept based on a theory from psychology.
– Evaluate: Observe users and interview them after they have used the system.
– Theorize: Describe how your system can be said to support the underlying theory.
– Justify: Explain how the results of your evaluation supports or refutes the underlying theory.
Methodology confusions!
• First confusion: Design and creation should be the only strategy I use in my research.
• Second confusion: Development methodology is the same as research methodology.
How to increase the quality of your work?
(aka "How to get an A")• Focus on improving rigor and
relevance• Rigor: E.g. am I showing
relation to state-of-the-art in models, theories, technology? Am I novel?
• Relevance: Do I manage to motivate? Have I chosen a specific user group and have I planned evaluations with this user group?
Next week
• Interview, observation.• Deliver assignment 2.• Group 4 presents paper 4.
