Think about where your current websites or mobile apps fit into Maslow’s hierarchy of needs. Do they support the base of the pyramid, a higher but less critical level of needs, or a range of needs? Knowing this should help you set expectations for use and satisfaction.
Similarly, if you’re assessing a new product opportunity for a client or trying to discern what kind of site or app to design on your own, determine what type of needs it could meet. Could it satisfy fundamental needs or higher-level needs? Could it be used by a broad range of users or just a niche?
