what is UX design?

User experience (UX) is a set of experiences of all interactions that the user has with product or service. UX design refers to: each individual element that shapes that experience; how these elements affect the user’s feelings; how easily and efficiently the users of the product or service achieve the desired goal. Unlike the classic design process, which is mainly the result of personal visions of designers based on product owner requirements, UX design is a process of creating new products or improving existing ones that is primarily focused on the needs, expectations, desires and requirements of users. UX designers allow companies to better understand user needs and meet their expectations. By creating products and services that provide users with relevant, meaningful, useful and desired experiences, UX designers represent the bridge between the company and the users. UX design involves the design of the entire process of acquiring and integrating the product or service, including aspects of branding, design, usability and function.

UX design takes place through five iterative stages:

1. Empathize: research users' needs;
2. Define: articulate the problem or challenge that need to be solved; 
3. Ideate: challenge assumptions and create ideas;
4. Prototype: create solutions;
5. Test: try out solutions;

These five stages are iterating so that in the first cycle low-fidelity prototypes are made, in the second iteration high-fidelity prototypes, in the third iteration the product itself and in the eventual fourth or subsequent iterations the product is further improved.

Products and services created or improved by the UX design process meet seven key UX design requirements: 

1. Usefulness - product or service should have a purpose for the target users. In addition to the practical use, that purpose can also be entertainment, aesthetic appeal etc.

2. Usability - product or service should enable users to achieve their end objective with a product or service effectively and efficiently. The safety and comfort of using a product or service, as a significant competitive advantage, come as a result of the high degree of usability of the product or service.

3. Findability - ensures that the product or service and its contents can be easily found.

4. Credibility - refers to the properties of the product or service that allow users to believe in the product or service. It also includes the brand reputation.

5. Desirability - is conveyed through emotional design, application of aesthetic principles, branding, image and reputation of the product or service.

6. Accessibility – the product or service should be designed to be accessible to persons with disabilities, users who are temporarily disabled in some way as well as in adverse environmental conditions such as noise, rain/humidity, too low or strong light, etc.

7. Value - product or service should bring value both to the user who uses them and to the profit of the company that developed them. For users, the value of a product or service is usually the sum of all factors of the user experience, while different users evaluate each factor differently, so for some the most important factor will be desirability, for others usability, for others usefulness, etc.

The success and competitiveness of a product or service in the market largely depends on the degree to which these seven requirements are met.

why UX design?

UX is one of the deciding factors, if not the deciding factor, whether a product will disappear without a trace or achieve mass sales. The UX design process, above all, ensures that the product being developed is something that users want and will have market demand thereby reducing the risk of developing the wrong and uncompetitive product. Furthermore, thanks to UX design, costs and time required for product development are reduced, the need for product changes and product maintenance costs are reduced, the number of customer errors and customer support needs are reduced, productivity and revenue are increased, opportunity cost is reduced, users are more satisfied, they accept the product to a greater extent and have a better opinion of the brand. Therefore, it is not surprising at all that UX design is one of the fundamental pillars of the business policy of successful companies such as Apple, Google, Amazon, AirBnb, etc.

UX design is fully compatible with AGILE / SCRUM digital product development methodology.

The development of digital products using the UX design method, which has accessibility as one of the key requirements, eliminates the need for SEO because the requirements of e-accessibility cover and widely exceed all aspects of best SEO practice. The advantage of e-accessibility design over SEO is not only reflected in better results when it comes to ease of finding, but e-accessibility results in a far wider base of potential clients (99 million people with disabilities in the EU, 61 million people with disabilities in the USA, more than1/5 of the global population) and the product itself is more usable not only for people with disabilities but also for all other users. Also, e-accessibility is a legal obligation in the EU, US and almost all countries of the world including Montenegro. National Federation of the Blind received $6 million settlement after lawsuit against the company "Target", which didn’t fulfill the legal obligation of e-accessibility. Aside $6 million settlement and additional $3.7 million in attorney's fees and costs to the plaintiffs, Target also faced significant financial losses due to the boycott by customers, as well as the overall negative impact on the brand.
