User Testing: The Importance of Iterative Design in UX

User testing is an essential practice in the sphere of User Experience (UX) design and conducts research to integrate desirable, feasible and valuable product services. Today we will discuss why it is important to conduct a user test and understand why designers use such a methodology as the iterative design process to create great user experience.

Understanding Iterative Design

Design and development occurring in cycles known as iterations- and is characterized by progressively developing the design based on feedback from the users. This form of design ensures gradual enhancement of the designs leading to the realization of enhanced results over the others.

Importance in UX Design

Iterative design is a core part of UX design because every idea, hypothesis, and conjecture must be tested and refined based on users’ firsthand experience. When linking with user testing, one can easily discover parts of the interface that are completely problematic in terms of usability; fixing these problems, which can be done quite quickly if the designers involve user testing with each iteration of the product, can produce a more user-friendly product.

This part looks at the Process of User Testing:

Planning and Preparation

User testing as with any other exercise is initiated with a lot of planning and preparation. The process includes defining of goals and objectives, defining of target user groups, and creating test scripts and cases that are responsive for project goals. Moreover, designers have to choose the right and proper testing methods and tools to ensure the acquisition of the relevant data needed.

Conducting the Tests

Therefore, once designers are through with the planning phase, they can go ahead and conduct the tests on real users. In the testing sessions, the participant is required to accomplish a set of tasks or work on prototypes where their activities and comments are monitored and documented. This first-hand information proves rather useful when it comes to understanding the users’ behaviors in regard to the product and the areas requiring enhancement.

Analyzing Results and Feedback

In the end, after the testing sessions are over, will all designers help look at the test scenarios, which people have provided feedback on and discuss them. This includes the analysis of repetitions, frequencies and issues with the interaction and use of the system and website which occurred during tests. Overall, using this data, designers will be able to understand certain tendencies of users, and use this knowledge for future designing.

Iterative design and user testing are beneficial in the following ways:

Improved User Experience

This incremental design together with frequent usability testing will produce a more exceptional user experience. Describing the process of using a product being carried out in a precise sequence, designers are able to fine-tune all proposed designs with the help of feedback received to make a product more intuitive, more efficient and more enjoyable to use.

Reduced Development Costs

This is another advantage of carrying out iterative designs in that it has an ultimate possibility to bring about the reduced expenses in the development aspects. In this way, usability issues are caught before they compromise the project’s design, which may increase the costs of redesigning and redevelopment further down the line. Also, it eliminates instances whereby a product is developed, only to reach the market, and users are dissatisfied due to various usability problems that the design could have prevented.

Increased User Satisfaction

Finally, the results based on the ID and testing show the improvement of user satisfaction. Through Design with the User or User-Centered Design processes, where designers involve users and actively seek feedback, they prove a willingness to accommodate users’ requirements and wants. Consumers’ trust and devotion to a product can be built with the help of this kind of collaboration, thus providing for longevity of the product.

They also explain how to deal with common challenges in relation to collective decision-making, processes and procedures.

Recruiting Suitable Participants

The major drawback that can be frequently observed in user testing is the difficulty of finding participants who will represent the actual target user group. In order to address this issue, designers can use social networking websites for recruiting participants for interaction with actual designers; use online panels that consist of users who have agreed to take part in some research; going through the clients’ lists of customers and finding several people from each community who can be invited to the research.

Interpreting Feedback

It is always quite hard to deal with the feedback which users provide during the testing sessions, for example, if the feedback is rather contradictory or unclear. To overcome this challenge, designers should make use of information that is collected from different sources which include observation data, task completion percentage, and interviews also.

Keeping Feedback Over the Creative Vision

Designers may also experience conflict of interest particularly between users and themselves in regard to the specific design decisions. However, user needs and wants should be given attention but alongside with it are considerations for technical aspects, business goals, and constraints of the design. Achieving the best fit regarding the vision of designers on the one side and the users and their feedback on the other side is the main success factor when it comes to the development of new products.

User testing is defined as a method where a small set of users is engaged in the execution of a set of tasks in a prototype in order to assess the efficiency of the latter.

When applying this strategy, the health campaigner should start early and keep on testing.

Start user testing even before starting the design phase and proceed with the testing phase in intervals of the development. Usability testing can be done and implemented frequently and this way designers are always able to detect and rectify any problem that is related to usability hence they are able to make very large improvements in the future.

Set Clear Objectives

This means that before conducting the user tests for each round, goals and objectives for success should be laid down. When the goals are clear, it becomes easy to target the areas to be tested, as designers work towards providing useful information that the project aims at achieving.

Create Realistic Test Scenarios

Define practical assessment activities and cases that model the customers’ usage patterns of the given product. Designers should take the opportunity to generate realistic tests, thus helping them get statistically sound data about consumers.

Conclusion

Thus, user testing and iterative design remain as the key assets of any UX designer out there in the market. Thus, following the approaches that involve users in the design process, we can achieve not only the beautiful objects but also the efficient and satisfying ones. User experience design therefore presents an effective tool of implementing business strategy since it offers a competitive edge in the marketplace besides creating popular products in the market.

FAQs

How is user testing helpful in design considerations for UX?
User testing enables designers to test their hypotheses, assess the problem areas, and make proper design decisions grounded on the users’ feedback. The flow of design process showing users the possible alternatives will also help designers to develop better products which customers desire.

How many participants can be involved in the usage testing procedure?
The total of the participants involved in the user testing can be a number of people ranging from a few to tens. But usability practitioners prefer the minimum number of participants for a test to be five in order to identify most of the usability problems.

What are the types of prototypes used in user testing?
There are many prototypes that can be used during user testing, paper based prototypes to highly interactive ones. It is necessary to consider such parameters as the project’s time constraint, cost, and precision necessary to examine some layout features.

To what extend is it acceptable to engage users in testing while designing?:
User testing should be done at least in the beginning of the project but it’s better to do it in the beginning of the design process and then periodically make more tests during the next design/development phases. The rate of testing may also differ with the number of projects implemented especially with respect to the project schedule.

Schwarz & Silver (2000) identify some possible pitfalls that one can experience in user testing including the following:
Missteps with respect to user testing are the wrong participants chosen for the test, wrong questions being asked or leading/ambiguous questions, and wrong interpretation of feedback. Therefore, the following recommendations are suggested to prevent the aforementioned difficulties: Designers should; Provide appropriate user testing sessions with good planning, follow research guidelines and protocols, and integrate feedback from different sources.
