Article Draft
User experience design (UX design, UXD, UED, or XD) defines the experience a user would go through when interacting with a company, its services, and its products. User experience design is a User Centered Design approach because it considers the user's experience when using a product or platform. Research, data analysis, and test results drive design decisions in UX design rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance. UX design is also an element of the customer experience (CX), encompassing all aspects and stages of a customer's experience and interaction with a company.

History
User experience design is a conceptual design discipline rooted in human factors and ergonomics. This field has focused on the interaction between human users, machines, and contextual environments to design systems that address the user's experience. User experience became a positive insight for designers in the early 1990s with the proliferation of workplace computers. The term "user experience" was coined and brought to a broader audience by Donald Norman, a professor and researcher in design, usability, and cognitive science.

"I invented the term because I thought human interface and usability were too narrow. I wanted to cover all aspects of the person's experience with the system including industrial design graphics, the interface, the physical interaction and the manual. Since then the term has spread widely, so much so that it is starting to lose its meaning."

UX design testing
Usability testing is the most common method designers use to test their designs. The basic idea behind conducting a usability test is to check whether the design of a product or brand works well with the target users. The purpose of usability testing is to test whether the product’s design is successful and, if not, how it can be improved. When designers conduct tests, they are not testing for not the user but the design. Further, every design is evolving, with both UX design and design thinking moving toward Agile software development. The designers ensure they test every aspect of the final product by conducting usability testing as early and often as possible.

Usability tests play an important role in delivering a cohesive final product; however, various factors influence the testing process. Evaluating qualitative and quantitative methods provides an adequate picture of UX designs, and one of these quantitative methods is A/B testing (see Usability testing). Another key concept in the efficacy of UX design testing is the idea of a persona or the representation of the most common user of a certain website or program, and how these personas would interact with the design in question. At the core of UX design usability testing is the user; however, steps in automating design testing have been made, with Micron developing the Advanced Test Environment (ATE), which automates UX tests on Android-powered smartphones. While quantitative software tools that collect actionable data, such as loggers and mobile agents, provide insight into a user's experience, the qualitative responses that arise from live, user based UX design testing are lost. The ATE simulates a device's movement that affects design orientation and sensor operation to estimate the user's actual experience based on previously collected user testing data.
