This inspiration topic talks about the problem-solution-fit, mainly focusing aboput InVision. Products become meaningful when the provided solution fits the uncovered problem. This solution describes the way a problem will be solved. Thus, the problem-solution-fit defines the core user experience of a product. The concrete features are extending this experience and support the core experience, but they cannot replace it. Interaction design and visual design can make a product beautiful, easy-to-use, and delightful, but it can’t make the product meaningful. This is why a proper problem-solution-fit is so critical for the success of a product.
