Do you want to understand the needs of your users? Personas won’t cut it when it comes to products with more than a few facets, meaning that another, less one-dimensional approach is needed. We present Core Needs as a flexible framework to describe what users want, even if their needs change over time. We share our experience of implementing Core Needs throughout the company for product development and as a joint language for UX, marketing and product. We show how you can identify your users’ Core Needs, analyze them qualitatively, quantify their frequency and find approaches to implement them in your product.
