What demonstrates that a solution works technically?

The concept of "Proof of Concept" (POC) is crucial in demonstrating that a solution works technically. A POC is a prototype or early sample designed to test and validate specific aspects of a solution to ensure that it can achieve the desired functionality and prove that it is technically feasible. This is typically done on a smaller scale to confirm that the core idea can be translated into a working solution before investing in full-scale development.

In a POC, the focus is on showcasing the potential of the technology or the proposed solution in real-world scenarios, which helps stakeholders and decision-makers understand its practical application and effectiveness. It addresses key technical questions and allows for adjustments based on findings from the validation process.

Other approaches, like technical validation, feasibility studies, and operational assessments, focus on different aspects of evaluation and do not strictly demonstrate that a solution works technically. Thus, a POC is the most targeted and effective method for establishing technical viability in the context of developing a startup solution.
