The experience of a service or product's use is consistent of three main forces: "familiarity", "functional dependency," and "emotional attachment". These three forces are responsible for shifting a users' experience across three phases: "orientation", "incorporation", and "identification", respectively. The incorporation factor is the most significant user experience phase of the three. Incorporation makes long-term usability become much more important than the initial learnability, and the product's usefulness becomes the main factor impacting the product's overall value in the eye of the user. As the user accepts the product into their lives, it participates in normal social interactions, and integrates with part of the users self-identity that connects to others and creates a sense of community, building identification. The actual experience with the product has been found to be more influential to users' satisfaction than their prior expectations, though the act of anticipation and creation of expectations is a crucial part of the primary user experience. Sometimes anticipating experiences with a product becomes even more important, emotional, and memorable than the experiences itself.
