A proof of concept (PoC) is a focused test used to determine whether a proposed idea or technical approach is feasible. It helps a startup reduce uncertainty before committing to a larger product build or commercial rollout.
Start by identifying the riskiest assumption. This may concern technical feasibility, performance, integration, user workflow or another critical requirement. Define the minimum evidence needed to evaluate that assumption.
Choose a test method and set boundaries for time, cost, data and resources. Document the test conditions and results so that another person can understand what was demonstrated and what remains unproven.
A successful PoC does not automatically establish customer demand, commercial viability, security or scalability. Those may require separate tests. Use the findings to decide whether to proceed, redesign or stop.
