A proof of concept (POC) is a critical project that can determine the viability of your actual project later on1. It is used to verify whether the methods and technology to be used in the project are likely to work before investing financial resources into it1. If a POC determines that the current technology cannot support the proposed solution, the project manager should add this item to the issue log and explore possible resolution options with the team1. This is because the main goal of a POC is to use research and testing to verify the feasibility of the project1. Therefore, if the current technology is found to be unsupportive, it is crucial to explore other options to ensure the success of the project1. References:
