This document summarizes the TDT39 Empirical Research Methodology course. It is intended for students interested in research in real-world settings and will teach methods for exploring how and why information systems are designed, implemented, and used. The main deliverable is a research plan for the student's master's thesis. The plan will include the research purpose, contributions, method, participants, and paradigm. Students will meet with the instructor to discuss their plan and present it for feedback. The instructor is available for questions but students should consult their thesis supervisor for project-specific questions.
