There are several classic definition models about user experience in the industry, which are briefly summarized as follows:
Peter Morville
The value of product design is divided into six modules: Useful, Usable, Desirable, Findable and Accessible. Credible (trust) and Valuable (value)
Honeycomb model can help people quickly understand requirements and define the priority of requirements, and comprehensively consider the balance between environment, content and users, which is conducive to improving design for specific purposes and examining value.
5E principle
starting from usability, this paper studies five attributes of products: Effective effectiveness, Efficient efficiency, Engaging attraction, Error tolerant and Easy to learn. These five attributes are not necessarily equally important. For different products and different users, some attributes should be placed in a secondary position. The value brought by thinking through 5E goes further than simply understanding the interests of users. It can balance when necessary, give design methods and identify directions.
Cycle model of user experience
User experience is not a simple Action, it is a cycle of trying to satisfy hopes, dreams, needs and desires, which consists of these actions: Triggering trigger, expecting Expectation, approaching Proximity, knowing Awareness, contacting Connection, taking action, responding to Response and Evaluation.
By comparing their expectations with the response of the system, users can be satisfied, or adjust their expectations, or give up using the system, and so on.
emotional interaction design model
this model puts forward six maturity levels that most technical products and services will experience, from "hey, this thing can work" to "it makes my life full of meaning", namely: practical (useful, as planned), reliable (effective and accurate), Available (easy to use), easy to use (quick and convenient, without special memory), exciting (unforgettable experience worthy of publicity), far-reaching (significant to individuals, brand first choice).
This model fully reflects the attention levels of the current user experience, with high conceptual awareness.
Therefore, I recommend using it as the basic model for the test team to understand the user experience, and we can find vivid measurable examples from each level, which is convenient for members to understand, such as:
Practical: measure how many users are using this function and how active they are.
reliability: measure stability index, service stability, interface availability, etc.
Available: measure the completion rate/accuracy rate of key tasks of novice users.
ease of use: measure the average completion time of key tasks, the number of steps, etc.
Pleasant: Look at the customer satisfaction survey of product use, etc.
it has far-reaching significance: look at the proportion of users' preferred brands, brand NPS ranking, etc.
