Usability goals are the minimum measure of a tool's learnability, memorability, efficiency, error frequency, and satisfaction that must be achieved before a product or feature is released. By defining and continuously measuring usability metrics over time, teams can measure the change in usability as the product grows. Usability goals can also be an important design metric or KPI used to align the design, product and business teams on the overall success of a product. For a website, the only usability goal is "easy to use".
However, the goal of user experience refers to the overall feeling the user has before, during and after using the website. Therefore, usability relates to the ease with which the user completes the task while using the site; user experience focuses on the user's perception of how the site interacts with them. An improved user experience aims to improve the overall feeling users have when using a web system. User experience goals focus on helping users gain a positive perception of how a website or web application interacts with them.
From the definition, we can understand that usability is only a limited aspect of user experience. Usability focuses more on the functional aspects of a product. However, user experience usually refers to almost all aspects that can make users enjoy a product. However, the concept of user experience is about the overall feeling a user has before, during and after using a website.
Usability relates to how easy it is for the user to complete a task while using the site; user experience focuses on the user's perception of how the site interacts with them. Usability is the measure of ease of use and learning. It is the ability and ease with which users make their way through the application. The goal of designing and testing usability is to create a user interface that is easy to learn and that allows users to get the value they expect from your application, website or wearable in the most efficient and effective way possible.
Usability focuses on the aspects of the user interface that affect users' ability to achieve the goal they want to achieve by interacting with the website, application or device. In short, better usability helps improve the overall user experience, which is what user-centred design is all about. For example, if registration is difficult to learn, users are likely to take longer to complete the task, exceeding efficiency goals, and be less accurate, failing in effectiveness. User experience (UX) focuses on getting to know users thoroughly, what they need, what they value, their capabilities and also their limitations.
Users may need to access new functionality, expand their scope of work, explore new options or change their own workflow or process. Users often attach little importance to features that they simply expect to be well represented in the interface. The use of user personas and user value stories can be very valuable in designing and testing the user experience. The key to designing and testing the user experience is to develop a deep understanding of the users of the user interface.
Allow users to build not only on their prior knowledge of computer systems, but also on any interaction patterns they have learned through use in a predictable way. This refers to the degree to which products are effective, easy to use, easy to learn, efficient, error-free and satisfying to users. Understanding the five characteristics of usability - effective, efficient, attractive, error tolerant and easy to learn - helps guide user-centred design tasks towards the goal of usable products. However, the more the technical terms come out, the less they can understand the difference, especially usability and user experience are confused by many designers.
If it arouses a good emotional experience and makes the user feel happy and pleasant, then the user experience design of the product is good. Customer happiness is a key success factor for virtually every organisation; and therefore, it is critical to understand the role of each discipline in creating a seamless customer experience. Whether users are novices or experts, a well-designed and usable interface can also drive sales and increase the number of customers. User interface design and user experience copywriting have many things in common, and both pursue one goal: to attract users to a product.
