When deciding which type of prototype to use for your product or service, there is no one-size-fits-all approach. You must consider the stage of development, the goal of prototyping, and the resources and constraints you have. For instance, if you are in the early stages of development, you may want to use low-fidelity prototypes that are easy and fast to create and change. This will allow you to test your basic assumptions and hypotheses. Alternatively, if you are in the later stages of development, you may want to use high-fidelity prototypes that are more realistic and detailed. This will allow you to test your functionality and usability. Additionally, depending on what you want to learn or achieve with your prototyping, different types of prototypes may be used. For example, if you want to test your value proposition, a storyboard or a landing page might be appropriate. If you want to test usability, a wireframe or a prototype simulating the user interface and interactions could be suitable. Finally, depending on your budget, time, skills, and tools, you may need to use different materials or tools for prototyping. Low-cost and simple materials such as paper or cardboard may be used if resources are limited. If more resources are available, more sophisticated and expensive materials or tools such as 3D printing or software can be utilized.
