I liked the business approach to this assignment. It was also creative to observe an outside environment (biking culture on campus). And you had good quant data from doing this. I liked your problem statements because instead of honing in on your interviewees’ personal needs, you considered systems/businesses on a whole.
I wonder, did you do some observation first and the interviews later? I wish you described a little more on how you decided on these three products/services. Although I like the way you divided up you interviews (who, why, what questions, results, etc.), I wish you had written the summary more in sentence form. I think it will help communicate key aspects of the conversations.
What if instead of uploading scans of your notebook (for the interview and for the market survey), you just highlighted relevant links and quotes? What if you recruited/found new users of the products too?
