Wicked Problems. Design Challenge: City Mobility

What is a wicked problem?

The Design Thinking

The modern design process is divided into two distinct phases: problem definition and problem-solving.

The Challenge: City Mobility

My team and I choose City mobility as our lead topic, to learn and put into practice the Design Thinking. We received the following brief:

Five Stages of Design Thinking


1.Empathise | Develop a deep understanding of the problem
1.1 User research
1.1.1 User Research. Quantitative Method: Survey
User Research. Qualitative Method: Interview


3.Ideate | Brainstorm all possible solution (good and bad)
3.1 Ideation / Brainstorm


Day 1

Lean Canvas - City Mobility
  • 44% of participants said that they use public transportation because it is Environmentally Friendly
  • 34.1% of participants said that their dream public transportation is a Light-Speed Train

3.Ideate | Brainstorm all possible solution (good and bad)

Crazy 8’s Ideation method
  • They should be self explanatory and simple enough for the user.
  • Lastly, we avoided to use design visuals details like colours, images or typography to focus the attention of the quality of the user experience and its functionality.
  1. The app displays a list of options and the user selects one
  2. The user can Track the route . This implemented feature follows the status of this specific route on real time. If any of the transportations of this route is affected by any inconvenient (like a delay) it will be immediately communicated to the user.
  3. As said, if the user gets a notification describing the eventual problem, the app would show another list of alternative routes the user can rapidly chose, select and track again.
Mid-fi Wireframes — City mobility
  • Visuals work better than words
    — Most of the users got to the next task faster when visuals were presented
    rather explanation in words.
  • Track it feature
    — Users loved the real-time update on their chosen route
    — “It makes me feel more in control
    — “Wow! Super cool! :)


Beside the user test, we got the opportunity to present the whole project to our IronHack mates and instructors. This was a good moment to get insightful and constructive inputs from our colleagues that had the same challenge with a different topic and faced the same Design Thinking process but from their different points of views.
We also practiced our presentation skills and this is something that personally I have to improve.

  • Some Grows:
    - “Review and connect the research to the converging part.”
    - “Synthesis better the research and decision points during the process.
    - “A little less info on the slides might make it easier to follow the your story.
    - “Maybe some simple visuals to let the important information stand out.

Learnings and Conclusions

This was the first time I applied the whole process of a Design Thinking including different methodologies and I have to say that it was a big and very inspirational challenge . I learnt a lot and I specially understood that the Design Thinking is a process you could apply, not just on Digital products, but on every decision that involves any User experience.
