Solo project (OpenClassrooms Project)

A multinational brand reached out to me to conduct a study on how people drink coffee. I conducted Ethnography, Competitor Analysis, Created Personas & Journey Map, and Synthesized my Findings.
How do people in Japan drink coffee and what are the keys that are important to users and the pain points they face?
Based on the Double Diamond Design Thinking Process. First, Discover-Research phase: I conducted Secondary research (macro-environmental analysis and competitive analysis) to better understand the Japanese coffee market. Then I conducted Primary research (field observations and user interviews). After that, as the Define-Synthesis phase, I did Affinity Diagrams, Personas and Journey Maps to find insights.

The research followed the Double Diamond Design Thinking Process: Discover-Research phase (Secondary and Primary research) and Define-Synthesis phase (Affinity Diagrams, Personas, Journey Maps).
