Five Stages of Design Thinking




Lean Canvas - City Mobility

Crazy 8’s Ideation method
  • This wireframe displays the basic elements of our app using simple shapes.
  • 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 user writes a Start / End destinations
  2. The app displays a list of options and the user selects one
  3. 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.
  4. 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
  • Fewer and specific buttons/options
    — Too many words, vague phrases, or too much freedom confuse users
    — Fewer and specific options lead to faster decision making with less confusion
  • 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! :)


  • Some Glows:
    - “Research methods applied well and the definition process to understand the user needs.”
    - “The ideation phase was really nice to see, and the end result (solution) was really good
  • 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.
