Present a design solution by communicating how it meets the stakeholders’ needs and the design specifications, using appropriate visual, physical, and verbal evidence. The presentation should enable stakeholders to understand, evaluate, and give useful feedback on the proposed solution.
The Process
In B2.1 The design process, a designer must explain how and why the solution addresses the identified problem.
First, identify the audience. Stakeholders, including users, clients, manufacturers, retailers, and regulators, have different priorities and technical knowledge. Adapt the format and terminology accordingly.
Use annotated sketches, technical drawings, CAD models, renderings, simulations, or physical prototypes. Label important features rather than leaving them for the audience to interpret.
| Presentation element | Purpose |
|---|---|
| Design context and user need | Reminds stakeholders what problem is being solved |
| Final design proposal | Shows form, function, dimensions, materials, and operation |
| Specification evidence | Demonstrates how measurable requirements have been met |
| Prototype or model | Allows stakeholders to inspect, test, or experience the solution |
| Justification | Explains design decisions using research and testing evidence |
| Constraints and trade-offs | Acknowledges limitations involving cost, manufacture, sustainability, or performance |
| Feedback method | Collects structured responses through interviews, surveys, observation, or user testing |
Compare feedback with the specifications. It may reveal usability problems, unmet requirements, or improvements, leading to iteration and refinement.
A common misconception is that an attractive rendering is sufficient. Visual quality supports communication, but a strong presentation must also provide evidence that the solution is feasible and meets stakeholder needs.
Exam Technique
For an IB question asking you to explain or justify presentation choices, link each communication method to a stakeholder and purpose. Avoid listing methods only; explain why, for example, a prototype provides more useful user feedback than a technical drawing, while a manufacturer may require precise CAD dimensions and material information.
