For this challenge I interviewed a dear friend that uses her backpack almost everyday. 

Interview transcription:

How many backpacks do you own and why? One cause I used to have only bags instead of backpacks but since I carry heavy books they didn't last long.

Because I the straps seemed strong and I just liked it.

Mainly heavy books, sometimes my laptop or iPad.

They look uncomfortable besides no one uses them.

Yes, inside there is one where I put my laptop or iPad. Outside it has two on the sides and one in the front.

On the two side pockets I try to fit in my water bottle but it is really difficult. In the front pocket I carry my glasses, phone and wallet.

I like the front pocket because I can access everything quickly. I hate the side pockets because my bottles never fit in.

I haven't tested.. Ive been very careful with this backpack. I usually left my bags on the floor and the bottom ripped but I carry this one all the time and try to take the best care.

I liked it.. There was a black version but I liked this one the most. I thought it was going to get dirty quickly because it has white stripes but it hasnt..so.. I guess I chose right. 

After the interview I created a persona to represent my friends needs and desires.

Then I wrote some of the characteristics that the backpack should have and asked for feedback. 

I wrote on 4 post-its the main characteristics the proposal should include after asking the user and discussing which were the most important.

I made some sketches to represent some of the ideas that could be implemented on Anne's backpack.

Material proposal for straps: Ripstop or ballistic nylon.

I will meet my friend next week to receive feedback on the sketches and continue developing the proposal... :)
