Iterative Modelling, Testing, and Refinement
Note
- Iterative Modelling is a cyclical process where designers create, test, and refine a model repeatedly.
- This approach contrasts with linear methods, where each stage is completed before moving to the next.
Note
Iterative modelling is not limited to physical prototypes. It includes digital models, sketches, and even conceptual frameworks.
The Model, Test, Refine Cycle
- Model
- Create a prototype (sketch, physical model, CAD)
- Focus on form, function, or usability depending on the stage
- Test
- Evaluate performance, user interaction, or durability
- Use feedback and testing data to assess alignment with design criteria
- Refine
- Make improvements to address issues or enhance performance
- Update the model and test again
Tip
When testing a model, focus on specific criteria such as functionality, usability, and aesthetics. This targeted approach ensures that refinements address the most critical aspects of the design.
Example
In the development of the Tesla Model S, engineers used iterative modelling to refine the car's aerodynamics, battery performance, and user interface, resulting in a highly efficient and user-friendly vehicle.
Techniques for Effective Iteration
- Rapid Prototyping: Quickly create models using tools like 3D printing or digital simulations.
- User Testing: Involve end-users in the testing process to gather authentic feedback.
- Data-Driven Refinement: Use quantitative and qualitative data to guide improvements.
Note
Iteration is not about achieving perfection in one cycle. It's about making incremental improvements that collectively lead to a successful design.
Note
Document Your Iteration
- Photograph each prototype
- Note key changes and the reason behind them
- Keep a development log to show clear evidence of your design evolution
