Design Principles: The Philosophy of UX

The visual principles of harmony, unity, contrast, emphasis, variety, balance, proportion, repetition, texture and movement (and others) are widely recognized and practiced, even when they aren’t formally articulated. But creating a good design doesn’t automatically mean creating a good experience.
In order for us to cultivate positive experiences for our users, we need to establish a set of guiding principles for experience design. Guiding principles are the broad philosophy or fundamental beliefs that steer an organization, team or individual’s decision making, irrespective of the project goals, constraints, or resources.
