How does high-fidelity prototyping differ from evolutionary prototyping? What weaknesses are introduced to a product’s success as a result of integrating a set of high-fidelity prototypes to make a final product?

Generally computer-based and allows realistic interactions. This prototype is as close to the final product as the team can create and is much more effective at collecting true performance data from human or user input. This prototype is also generally used as the demonstration version to clients or internal stakeholders. (Assistant Secretary for Public Affairs, n.d.)
This approach initially breaks the system into independent modules with their functionality. In an iterative process, testers demonstrate each component to a test group until a final version is decided based on user feedback. Like the biological process of evolution, this prototyping approach moves through a series of refinements until the best version has evolved. (Evolutionary Prototype Definition., n.d.)
Weakness of the High-Fidelity Approach
The greatest challenge to the high-fidelity approach for most teams is the cost and time associated with the process. Due to the complete model approach for testing, the building process is long, and any changes require extensive retooling time. The second biggest weakness that this approach is associated with is the system as a whole is susceptible to a single issue. Since the system is delivered in an almost final form, making changes to one piece can have very adverse effects on another including complete system failure. Often, the designers and programmers of the system have difficulty accepting change suggestions as they have already created something that, in their mind, is very close to complete. Lastly, from a test point of view, the system’s aesthetics often supersede the functionality considerations, and functionality is lessened. (Khatri, 2021)
