Summary
The document explores the purpose and use of prototypes in designing interactive computer systems. It argues that the effectiveness of a prototype depends less on its physical attributes and more on its ability to answer specific design questions. Houde and Hill propose a model that categorizes prototypes based on three dimensions: role, look and feel, and implementation. They provide various real-world examples to illustrate how prototypes can be used to focus on different aspects of a design project.
Takeaway
A key professional insight is the importance of aligning the type of prototype with the specific design questions it intends to answer. This approach ensures efficient use of resources and fosters clarity in the design process. The emphasis on purpose over physical characteristics of prototypes is crucial for effective design in interactive systems.
Real-world Connection
The concept of focusing prototypes on specific design dimensions can be applied in various fields beyond computer systems, such as product design or architecture. For instance, in architecture, models (prototypes) are often used to explore spatial relationships (role), aesthetic appeal (look and feel), and structural integrity (implementation).
Burning Question
A question that arises is how to balance the need for comprehensive prototyping (covering all three dimensions) with the constraints of time and resources, especially in fast-paced design environments. How do designers decide when a prototype is ‘good enough’ to proceed with further development stages?
