The type of prototype that can simply be created using paper and pencil is the throw-away prototype. This approach involves quickly sketching out designs to visualize concepts without investing significant time or resources into technology or detailed development. The fundamental idea behind throw-away prototyping is that the prototype is not meant to be part of the final product but serves as a means to explore ideas, gather feedback, and clarify requirements early in the development process.

This method is particularly useful in the initial stages of a project when stakeholders need to understand design concepts or when there are multiple ideas to evaluate. Since the prototype is made from simple materials like paper and pencil, it allows for rapid iterations and changes based on user or stakeholder feedback. The simplicity of this method also encourages participation from various stakeholders who may not have technical skills, ensuring their perspectives are included in the design process.

Evolutionary prototypes, on the other hand, are refined through iterative cycles of development, which typically requires more sophisticated tools and technologies. Heterogeneous prototypes usually incorporate different formats or technologies, focusing on integrating various systems, and functional prototypes are intended to demonstrate specific functionalities, necessitating a greater level of detail and technical implementation. Thus, throw-away prototyping stands out as the approach that facilitates quick, low-fidelity
