Preparation
- Establish the purpose of the prototypes: they can be solutions to a problem, product designs, service proposals, etc.
- Clarify the criteria or aspects that will be evaluated during the feedback process (e.g., usability, innovation, impact).
- Materials for physical prototypes: cardboard, paper, modeling clay, adhesive tape, markers, etc.
- Digital tools for virtual prototypes: design software, presentation tools, modeling applications.
- Exhibition elements: tables, panels, whiteboards, labels.
- Set up a spacious area where teams can display their prototypes and participants can move around comfortably.
- If online, prepare a platform that allows sharing and commenting on digital prototypes (e.g., Miro, MURAL, Padlet).
Step-by-step instructions
Introduction to the purpose
- Explain the objective of the activity and the importance of feedback in the design process.
- Emphasize that prototypes are initial models, not final products; they are meant to be iterated and improved.
Team formation and prototype creation
- Divide participants into small teams (3-5 people).
- Each team works on developing a prototype of their idea using the available materials.
- Set a time limit for creation (e.g., 60-90 minutes) to keep the activity dynamic.
Exhibition preparation
- Once the prototypes are completed, teams set up their display space in the gallery.
- They can include brief descriptions, images, diagrams, or any elements that help explain their prototype.
Gallery walk
- Participants walk through the gallery, visiting other teams’ prototypes.
- They can move in groups or freely, ensuring everyone has the opportunity to see each prototype.
Constructive feedback
- Encourage visitors to provide constructive feedback.
- You can provide sticky notes or feedback cards for participants to write their observations and leave them at each prototype station.
- Suggest that feedback be specific, focusing on strengths and areas for improvement.
Team discussion
- After the gallery walk, each team reviews the feedback they received.
- They discuss how they can incorporate suggestions to improve their prototype.
- Teams can plan future iterations or immediate adjustments.
Closure and reflection
- Gather all participants to share insights and key learnings.
- Reflect on the value of collaboration and feedback in the creative process.
- Encourage teams to continue developing their ideas beyond the activity.
Materials
- Paper, cardboard, modeling clay, wooden sticks, fabric, etc.
- Scissors, glue, adhesive tape.
- Markers, colored pencils.
- Computers or tablets.
- Design software.
- Internet access and collaborative tools.
- Tables or panels to display prototypes.
- Labels or posters with the project name and team.
- Sticky notes or feedback cards.
Platforms
For virtual sessions or collaborative documentation.
Practical recommendations
Encourage a respectful and open environment
Ensure that feedback is constructive and that everyone feels comfortable sharing and receiving comments.
Variety of materials
Provide a range of materials so teams can be creative in representing their ideas.
Time management
Set clear time limits for each stage of the activity and communicate them to participants.
Documentation
Encourage teams to document their prototypes and the feedback received for future reference.
Adaptability
The activity can be adjusted to include multiple rounds of prototyping and feedback, promoting deeper iterations.
