This definition can be expanded, and made more comprehensive, by including five characteristics which must be met for the users of a product: Effective Efficient Engaging Error Tolerant Easy to Learn Effective. Effectiveness is the completeness and accuracy with which users achieve specified goals. It can sometimes be difficult to separate effectiveness from efficiency, but they are not the same. Efficiency is concerned primarily with how quickly a task can be completed, while effectiveness considers how well the work is done.
Not all tasks require efficiency to be the first principle. This assumes, of course, that the designer has not created an annoying or over-controlling interface in the name of effectiveness. The quality of the user assistance built into the interface can have a strong impact on effectiveness. The effectiveness of an interface often relies on the presentation of choices in a way that is clearly understandable to the user. The more informative an interface can be, the better users are able to work in it without problems. Another design strategy to increase effectiveness is to offer redundant navigation, especially for ambiguous situations.
Although this may create inefficient paths, it allows the user to work effectively by making more than one choice lead to the correct outcome. This can be especially valuable in interfaces which support infrequent users or those often unfamiliar with the content domain.
Efficiency can be described as the speed with accuracy in which users can complete the tasks for which they use the product. ISO defines efficiency as the total resources expended in a task. Navigation design elements such as keyboard shortcuts, menus, links and other buttons all have an impact on efficiency. When they are well-designed, with clearly expressed actions, less time and effort are needed for the user to make navigation and action choices.. Making the right choices for efficient use of the software depends on an understanding of the users and how they prefer to work.
For example, are they likely to use the interface infrequently or to be habitual users who might learn hidden controls and shortcuts?

Do they use the keyboard, mouse or other input devices? For example, keyboard shortcuts can be extremely efficient for proficient users who work with the interface intensively. If they are the primary interaction tool, they can slow down users who are unfamiliar with them, or with the software. Similarly, an interface structured around a set of hierarchical choices which may be the best solution for one-time or infrequent users, might be frustratingly slow as the only way of interacting with a frequently-used program.
An interface is engaging if it is pleasant and satisfying to use. The visual design is the most obvious element of this characteristic. But more subtle aspects of the interface also affect how engaging it is. Equally important is the style of the interaction which might range from a game-like simulation to a simple menu-command system.
Introduction to User-Centered Design
Like all usability characteristics, these qualities must be appropriate to the tasks, users and context. The style of engagement that is satisfying for a repetitive work tool is different than an e-commerce site. Even within the same class of interfaces, different users may have widely divergent needs. What is important is that the design meet the expectations and needs of the people who must use the interface. The ultimate goal is a system which has no errors.
But, product developers are human, and computer systems far from perfect, so errors may occur. Note that a highly usable interface might treat error messages as part of the interface, including not only a clear description of the problem, but also direct links to choices for a path to correct the problem. Errors might also occur because the designer did not predict the full range of ways that a user might interact with the program. For example, if a required element is missing simply presenting a way to fill in that data can make an error message look more like a wizard.
If a choice is not made, it can be presented without any punitive language. However, it is important to note that it is possible for an interface to become intrusive, or too actively predictive. Some guidelines for preventing errors are: Make it difficult to take incorrect actions.

Design links and buttons to be distinctive, use clear language, avoiding technical jargon, and be sure that dependent fields or choices appear together. Make it difficult to take invalid actions. Limit choices when possible to those which are correct, provide clear examples for data entry, present only appropriate navigation options.
Make it difficult to take irreversible actions. Provide the ability to back track, provide means to undo or reverse actions, avoid dead-end screens. Plan for the unexpected. Its scientifically-validated collection of tools, aimed to help make informed hiring selection decisions and avoid costly regrets, needed enhanced cohesion and focus. While effective, the existing system had grown over time without the incorporation of a comprehensive UX strategy that could keep it grounded.
Applying the User-Centered Design Process
This was resulting in experiences that sometimes were overly complicated or challenging for customers to utilize. In addition, some members of our team took it upon themselves to publish a case study , which elucidates the palate and functionalities added to the new design of WonScore. To understand Wonderlic as a company and the unique challenges it faced, the team implemented a standard, proven user-centered design process over the course of eight months.
In any user-centered design UCD design program, participants learn that the fundamentals of UX design always revolve around research, empathy, usability and actionability. Indeed, the general phases of the user-centered design process consists of 4 phases:. The user-centered design process started with a fixed duration discovery phase followed by a series of repeatable, overlapping interface design sprints. So what does this entail? We assessed the trust and credibility , considered their existing site structure and navigation , how their application allowed users to flow through processes, and the extent to which their site experience rich interactions.
Finally, we took a look at page focuses, any online forms they had, and how they were preventing errors for their users. If you thought that is where our evaluation ended, think again. After all of this was complete, we wrapped-up all our findings, framing the package as an initial set of areas for design opportunities in the next phase: concepting. We synthesized our findings into a series of goal-directed personas and journey maps , and we identified key themes such as the need for better group and personal decision making features, rapid understanding of information data, and contextual guidance within the interface for exploration during concepting.
As always, we had a fun time discovering and playing around with various potential user personas during this phase of the process.

For Wonderlic, this was a palpable experience; they were, for the first time, able to observe how their new tool would function and appear to users. Following concepting, we created a UX strategy roadmap that mapped the people, process, and feature-set of the future-state platform. This would allow us to organize the workstream for four overlapping design sprints that each led to Agile development sprints. Each design sprint was a repeatable set of services, which included the following:.
intranet.playzone.cz/profiles/recorder's/o-que-e-aliana-de-namoro.php The iterative nature of our design process allowed us to be flexible in our approach and make adjustments between sprints. Throughout this process, we worked closely with the Wonderlic team, meshing our design expertise with their existing product, market and customer knowledge. These explorations laid a foundation for the product we had been designing, and ensured that the end result would be a useful tool for the people whom it was intended, as well as an excellent addition to the already-impressive suite of Wonderlic products and services. As with most projects, we faced a number of unique challenges for shifting the user mindset and improving the overall user experience.
At the most basic level, our takeaway from primary user research was this: users i. Because most people who hire others are not experts at evaluating personality and cognitive skills assessment results. In other words, the functionality was somewhat complex, and users needed a certain amount of existing knowledge to comprehend and make use of what was offered.
The anticipation of possible errors has financial aspects, because the later errors are found in the software, the more expensive it becomes to eliminate them. Essentially, everything that helps to increase the usability of a website is beneficial for search engine optimization. Google also places great importance on the usability of websites. The concept of User Centered Design therefore meets the requirements of modern SEO, which is primarily focused on the needs of the user, and secondly on the requirements of search engines.
Mobile Optimization is a good example of how user centered design and search engine optimization go hand in hand. Mobile device friendliness is now a ranking factor. This also shows how far user friendliness influences trends - the majority of users worldwide use smart phones for web searches in many areas today. User Centered Design as a concept can promote search engine optimization in many areas. For example, the higher usability and better user experience can improve important KPIs such as bounce rate or dwell time. In fact, the method of user-centered design goes far beyond the benefits for search engine optimization and affects other online marketing areas such as e-mail marketing or newsletter marketing, for example by making e-mails even more user-centered.
In an even smaller area such as Conversion Optimization , user-oriented design can also play an important role, such as shopping basket optimization or Customer Journey optimization.
