What is the purpose of a proof of concept model?

The purpose of a proof of concept (PoC) model is to validate the design of a solution. A PoC is typically created to demonstrate that a certain concept or theory has the potential for real-world applicability. It allows stakeholders to test and evaluate key aspects of a design before moving into full-scale development. By validating the design, the PoC reduces the risks involved with the project by providing evidence that the planned solution can meet the intended objectives and requirements. This phase is crucial for making informed decisions about the feasibility and direction of the project.

In the context of the other options, testing user interface layouts might be part of the PoC process, but it is not the primary goal. Determining hardware requirements and budgeting for project costs are also important aspects of project development, but they are more related to planning and resource allocation rather than the core purpose of validating a specific design concept through a PoC.
