What UX Design Principles Make a Good User Experience?
Good design is easy to spot but often hard to pin down. What exactly makes a product effective to its users? Is it a matter of simplicity, structure, or functionality? The answer depends on the product in question.
In fact, what constitutes a good experience is often subjective and likely varies across people and contexts.

"Is it a good design? Well, Yeah."
User experience is how a person, the user, feels about interacting with, or experiencing, a product, system, or service. It includes a person's perceptions of utility, ease of use, and efficiency.

A User Experience Designer is responsible for all components of product development, including design, usability, function, branding, and marketing. Their job covers the end-to-end journey of a user's interaction with a product, as well as identifying new products and business prospects.

Every digital product that you’ve ever used started as a design challenge at one point. Before there was Facebook, Mark Zuckerberg had to sit down and think about what the best way was to display the comings and goings of his Harvard classmates. So, how does a design problem become an actual user-centered product?
UX designers typically use an existing framework/method to approach their work, from the initial concept through the final product launch. Some examples of these frameworks are: the user-centered design process, the UX design's five elements, the design thinking process, et al. “Design Sprints” are another very common method. Design Sprints are used to tackle a specific design problem by creating, prototyping, and testing ideas with users.
For a user to have a good experience, the product needs to be some combination of the following characteristics: Usable, Equitable, Enjoyable, and Useful.
If you want to evaluate a good UX design, it could be helpful to consider those same characteristics:

If a product is usable, its design, structure, and purpose are clear and easy to use.
You may ask questions like these when evaluating a product's usability: Is everything in the design easy to find? Is the design's functioning simple to understand? Is it possible for users to do certain activities inside the design? These questions might help you assess whether the design provides a usable experience when you analyze it.

If a product is equitable, it means a design is helpful to people with diverse abilities and backgrounds.
In other words, the product's design adapts to a broad audience and guarantees that all consumers, regardless of background, gender, color, or ability, have a high-quality experience. Giving individuals the tools they need to achieve their objectives and improve their quality of life is what equity means. Because people frequently require different tools and assistance depending on their requirements, equity extends beyond the notion of equality, in which everyone is provided equal resources. This is particularly crucial to remember for people who belong to often marginalized groups. You might pose questions like: Are the requirements of a diverse set of consumers considered when evaluating the equity of a product's UX? Is the design of the product inclusive to traditionally underrepresented and excluded groups? These questions might help you figure out if the design provides a fair experience.

If a product is enjoyable, it means the design delights the user.
The design reflects the user's thoughts or feelings and establishes a positive connection with them. It is not necessary for a product's design to be enjoyable for it to perform effectively. However, an enjoyable design complements a useful product and can improve the user's perception of the experience. You can ask questions like: Are there parts of the design that consider the user's sentiments when evaluating how enjoyable a product's UX is? Is the user's joy sparked by the design? Is the user engaged throughout the experience because of the design? These inquiries might help you determine whether the design provides an enjoyable experience.

A product is useful when it solves user problems.
The design solves a problem that the designer has identified in the user. It's worth noting that, while similar, the terms useful and usable have different meanings. Even if a product is useful, it isn't necessarily usable. The same may be said for the inverse. The difference between the two is that usability relates to the product's ability to operate well and be simple to use, whereas usefulness refers to the product's capacity to address user issues directly. You may pose questions such as: Does the design enhance the user's experience? while evaluating how helpful a product's UX is. Is there an issue that the design solves for the user? Does the design assist the user in achieving a specific objective? These questions might help you figure out if the design provides a good user experience.

As I mentioned earlier in the article, for every product you’ve ever used, SOMEONE had to have sat down and designed that product. Good products don’t just fall from the sky; they are designed by someone who probably used the same frameworks and processes discussed in this article.
Is it a good design? Well, it depends on whom you ask. What's good? And good for whom?

User interface is what a person sees and touches: layout, controls, typography, color. User experience is the whole of how the product works for them, including whether it solves their problem, how they got to it, and how it fits into their day. A beautiful interface on a product that does not do what users need is poor UX. The interface is one part of the experience, usually the most visible.
Watch real users attempt real tasks and note where they hesitate, backtrack or fail. Check analytics for drop-off points and repeated actions. Review support tickets for recurring confusion. Then score the product against the four qualities on this page: is it usable, equitable, enjoyable and useful. The combination of observation and data finds most of the serious problems; opinions from inside the team find the fewest.
A form that remembers what a user entered last time. A search that handles misspellings. An error message that says what to do next. A dashboard that opens on the number the user checks first. Default values that match the common case. None of these is visually striking. Good experience in business tools mostly means removing steps and decisions from tasks people do many times a day.
Because users differ in ability, device, connection and context, and a product that works only for the ideal user loses everyone else. Accessibility requirements such as keyboard navigation, contrast and screen reader support are also legal obligations in many markets. Designing for a wider range of users tends to improve the product for all of them: captions help in noisy rooms, and clear labels help in a hurry.
Typically a meaningful share of the design and development budget, with the exact figure depending on how much research and testing a project needs. The cost is front-loaded: understanding users and testing designs before code is written is cheaper than rebuilding features after launch. Projects that skip design work do not save the money; they spend it later on support, rework and features nobody uses.
