POC vs MVP is a comparison between a concept and an application that is ready to be published in the stores. While the intent between both the concept is the same – to validate an app idea, the stages in which they make an appearance are very different.
A proof of concept methodology is the first stage of idea validation – a stage where a small project is implemented for verifying if a concept can be implemented on the technical capability and business model grounds.
Minimum Viable Product approach, on the other hand, is a functional app that comes loaded with the prime features that best represent the application. This is the major difference between POC and MVP.
