Field work

We visited Gustav Hansen in Silkeborg November 2. We were shown around at the headquarter and at a constructionsite. At the constructionsite we interviewed some employees about how they handle the trash.

3. November we made interviews with Gustav Hansen’s partners online and afterwards we arranged notes and transcribed parts of the interviews.

Affinity diagram

Our process started with us grouping all the interesting data into categories of which interviewee it came from. As shown in the picture below, it was made with sticky notes in the program Miro.

We then split up the data, and put it into different categories with relevant headings to get a new grouping structure of our data.

Lastly we took the new categories and grouped our data even further and shaped it down into fever but more explanatory headlines.

Core Design

Here we focus on the core of the possible future ideas, that might solve some of our case-partners problems. 

Below are the quality criteria of our five innovation tracks, which where presented to our case-partner. The case-partner wanted us to continue with the tracks “The Smaller & more localized trash sorting” and “internal communication strategy/channel”

After meeting with our casepartner, which asked for us to move forward with the two core designs, “The Smaller & more localized trash sorting” and “internal communication strategy/channel”, we chose to combine the two and make one core design. 

“How Might We?”

To create the ideation board we each started out making three “How might we” (HMW) questions. Next we each voted and discussed on the ones we thought we should go further with. 

We picked one of the HMW’s created by each group member, then we voted and discussed again which ones we should go further on with. 
After voting we came to an agreement to combine three of the HMW’s together to create one principal one that we would go further on with. 

Ideation board (The first step)

From here on we could start our Ideation board. We started out placing our principal HMW in the middle, and then write our ideas in the squared around the principal HMW. 

After this we once again voted and discussed which ones we should go further on with. 

Ideation board (The second step)

In this step we added eight features to each of the five general ideas that we had chosen from the first step of this process.

Then we had to go from five ideas to three. Here, once again, we voted and discussed, and chose to go further with the following ideas. 


We then each made a video sketch based off the concepts we found the most interesting.

Video 1 – Based on the idea of an AR trash scanning app with image recognizing software, and real time navigation to more easily decide on a proper sorting option, and locate it.

Video 2 – A system that shows the statistics of the trash sorting. 

Video 3 – A system that shows the statistics of the trash sorting.

We have chosen to work with the final design based on a critique session and our own poll in which we could choose between number 1 and 2 from our skecthing. The choise fell on number 2.
