Some key principles include abstraction, reusability, maintainability, and simplicity. Think through major problems methodically—by making a list of pros and cons, for instance, or consulting with people you trust. Make extra time to think through tasks where snap decisions could cause significant problems, such as catching an important flight. As humans move throughout the world, they must process large amounts of information and make many choices with limited amounts of time.
Top 7 Tips on Becoming a Software Engineer
This heuristic doesn't mean you have to use a flat design — it's about making sure you're keeping the content and visual design focused on the essentials. Ensure that the visual elements of the interface support the user's primary goals. In general, the more evaluators you have, the more usability issues you will unearth, especially when the evaluators have different skill sets. However, Jakob Nielsen suggests that between three and five evaluators is sufficient. With five evaluators, you should be able to identify up to 75% of all issues. While increasing the number of evaluators will help you find more issues, it may not be worth the time and effort.

This is why providing help earlier and along the way can be helpful, through intuitive and responsive onboarding and tooltips. While you don’t want to go overboard and make your helpfulness a nuisance to your users, you do want to make their going to a help page something of a last resort. If, however, you type something in that the system doesn’t recognize or that doesn’t match the title or tags, you’ll find yourself on a page similar to a Google search containing a list of articles that might, hopefully, meet your needs. So as great as the help is, it relies to some degree on the user adapting to the system.
References and Where To Learn More
Principle three is that the system is Simple and Intuitive to use, regardless of the user’s level of knowledge, experience, language, or concentration. The design should support user expectations and take into account different languages and reading comprehension. It should not be unnecessarily complicated and should be organized in a way that facilitates access to the most important areas. We share user ID with Bugsnag and NewRelic to help us track errors and fix issues. As an undergraduate researcher, I analyzed how student design teams used the Design Heuristics tool in their class projects.
If you’ve ever tried to use your bank’s mobile app to transfer money, you’ve probably experienced a really great or really terrible example of this heuristic. The banking app N26, for example, makes it easy to see who you’ve sent money to in the past, or to set up a new recipient. If you had to set it up each time, you’d have to dig up bank details and input the information again every time. If you’ve ever filled out a poorly designed form and been met with an error message for an incorrect address or phone number, you’ve got first-hand experience in the importance of this heuristic.
Perhaps the most ubiquitous method is called ‘brainstorming’, a group process that involves suspending evaluation and generating as many different ideas as possible (Osborn Reference Osborn1957). Variants of this method, including ‘brainwriting’ (Paulus & Yang Reference Paulus and Yang2000), focus on developing a large quantity of ideas. UI/UX designers are always looking for strategies to improve the design process that can have a direct impact on the quality of their end products.
Additionally, in organizations with big design teams, it is always important to keep this moving, as multiple projects are going on at the same time. In such cases, having access to a resource like usability heuristics can come in handy. UI/UX designers can refer to specific usability guidelines, irrespective of the nature of the project, and assess a design quickly and easily. The engineering designers focused more on technical feasibility during ideation. For example, 10 of the engineers used insulation as a heating method, while the 12 industrial designers mostly used closure to maintain the heat without insulation. The engineers used a diverse range of cooking methods, such as the greenhouse effect, liquid, and pressure, while the industrial designers were more likely to use direct sunlight and a heated surface.
Heuristic evaluation is the activity of using a set of guidelines (heuristics) to evaluate if an interface is user-friendly. Let’s look at what heuristics are and how you can conduct a heuristic evaluation to improve the usability of your designs. Jakob’s Law states that people spend most of their time using digital products other than yours. Failing to maintain consistency may increase the users’ cognitive load by forcing them to learn something new. As technology continues to evolve, design heuristics in software engineering will also adapt to the changing landscape. Another interesting difference was that industrial designers more often used environmental contexts, such as bringing outdoor or indoor features into the concept.
How to Conduct a Heuristic Evaluation
In 1990, web usability pioneers Jakob Nielsen and Rolf Molich published the landmark article “Improving a Human-Computer Dialogue”. It contained a set of principles—or heuristics—which industry specialists soon began to adopt to assess interfaces in human-computer interaction. A heuristic is a fast and practical way to solve problems or make decisions. Heuristic evaluations are not intended to replace usability testing or research but can be a cost-effective and time-efficient method of identifying ways to improve the experience.
Read through the list of aspects used to evaluate the ease with which users can scan for the necessary information. Inspect the interactive elements and wait-time reactions in the product, and additionally, judge whether these aspects meet user expectations and further educates them to hint at the potential response.

And the best way to discover these commonalities is by conducting a competitive UX analysis. This process will help you to find what competing products are doing and what you might be able to improve on. Look for points along the user journey where mistakes are more likely to be made or when users are most likely to want to edit information, and find ways to make that task as easy and simple as possible. Minimize the user's memory load by making elements, actions, and options visible. The user should not have to remember information from one part of the interface to another. Information required to use the design (e.g. field labels or menu items) should be visible or easily retrievable when needed.
Understanding commonly unhelpful heuristics, and identifying situations where they could affect behavior, may help individuals avoid such mental pitfalls. The anchoring heuristic, or anchoring bias, occurs when someone relies more heavily on the first piece of information learned when making a choice, even if it's not the most relevant. The study of heuristics was developed by renowned psychologists Daniel Kahneman and Amos Tversky. Starting in the 1970s, Kahneman and Tversky identified several different kinds of heuristics, most notably the availability heuristic and the anchoring heuristic. Heuristics are not unique to humans; animals use heuristics that, though less complex, also serve to simplify decision-making and reduce cognitive load.
However, as discussed in the video, it may not be as effective as testing with real users when it comes to understanding the user experience fully. Heuristic evaluations, performed by experts, assess whether solutions conform to established usability guidelines, providing critical insights, especially in the early stages of design. Nonetheless, optimal outcomes usually result from combining this method with user testing, allowing designers to address expert opinions and real user experiences effectively. However, the diversity of concepts within a set showed a negative relationship, where more heuristic use was correlated with a less diverse set of concepts. This finding may be due to the sequence of concepts generated using design heuristics, where ideas based on new heuristics are added onto earlier concepts to produce new ones.
In this tutorial, we’ve taken a deep dive into what a heuristic evaluation is and how you and your team can successfully perform this simple assessment to enhance your product and reduce usability issues. We’ve also seen what direct benefits teams and companies can experience when adopting this approach; from the speed with which it can deliver results to its cost effectiveness. The individual performing the evaluation can simply act as the end-user themselves.
Here’s a take on the original heuristics but with a twist by adding a few more to account for aesthetics and joy. Service design can help our organizations innovate customer experience and build brand loyalty — and it’s great for small businesses. Because the purpose of the evaluation is more problem finding than problem solving, solutions should not necessarily be expected at this stage.
