This glossary aims at presenting specific words, terms and laws about user research and user experience design. The user research and UX design glossary is not exhaustif and constantly improved by Ferpection team. Don’t hesitate to write at [email protected] if you want to propose a suggestion.
A/B testing, also known as split testing, is a method of comparing two versions of online content against each other to determine which one drives more conversions and revenue.
Derived from the Scrum method, an agile sprint is a period of time during which a defined objective must be completed and ready to be reviewed. Commonly, a sprint lasts from a week to a month, but each sprint must always be the same length. The work to be developed during the sprint must be prepared beforehand and must not be changed once the sprint has started. At the end of the sprint, an evaluation of the work done allows you to continue in the same direction or change course.
A type of prototype that gives a visual representation of the user interface of a website or software application. Unlike static wireframes, in simulation clickable wireframes respond to user interaction.
The difference with a persona is that the archetype is more based on behaviours, whereas the persona is oriented to socio-demographic data.
A questionnaire elaborated by Hassenzahl and his colleagues in 2003, it is a reference in user research. It allows to evaluate hedonic and pragmatic characteristics of an interactive system.
Testing against a set of standard best practices or past performance metrics.
Process for generating creative ideas and solutions through intensive and freewheeling group discussion. Every participant is encouraged to think aloud and suggest as many ideas as possible, no matter seemingly how outlandish or bizarre.
A technique using either actual cards or software, whereby users generate an information hierarchy that can then form the basis of an information architecture or navigation menu.
The circular design is playing an essential role in this new nonlinear economy through building a design thinking process that intends to build new business models that consider the future of the product waste in multiple dimensions.
User research method to generate new feature ideas with 8 participants. Each participant draws in a screen or feature for one minute (so, 8 minutes in a total) and then share it with the rest of the participants to improve design. At the end of the session, there is a convergence phase with “Best of” to see what features are most liked by participants.
Or user experience : Refers to a person’s subjective feeling and attitudes about using a particular product or service, online or offline. It includes the functional scope, product and brand's perception, psychological expectations, and actual emotional feelings. These are indispensable parts of the user experience. It's important to think the user experience (or customer experience) in its entirety, considering every touchpoints between the user and the brand.
A design sprint is a time-constrained, five-phase process that uses design thinking with the aim of reducing the risk when bringing a new product, service or a feature to the market. The 5 phases, one for each day of the week, are: Understand / Sketch / Decide / Prototype / Test. This method originates within GV (formerly, Google Ventures) from a vision to grow UX culture.
Design thinking is a human-centered approach to innovation that draws from the designer's toolkit to integrate the needs of people, the possibilities of technology, and the requirements for business success.
Research methodology that involves providing participants with the materials and structure to record daily events, tasks and perceptions around a given subject in order to gain insight into their behaviour and needs over time.
First phase of the creation process, the discovery phase aims at knowing your potential users, understanding their habits and needs on a specific subject, in order to design a solution that will fit those.
An empathy map is a collaborative visualization used to articulate what we know about a particular type of user. It externalizes knowledge about users in order to 1) create a shared understanding of user needs, and 2) aid in decision making.
Or shadowing. A methodolgy where the researcher accompanies the user and observes how they use the product or service within their natural environment.
A user experience map shows the users’ needs, expectations, wants, and potential route to reach a particular goal.
Eye tracking is the process of measuring eye activity. It uses tools like special glasses to record what users look at and in what order.
Is a predictive model of human movement primarily used in human–computer interaction and ergonomics. This scientific law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target.
Is a traditional observational technique that allows a design researcher to collect data by seeing and listening. This method helps the researcher in secretly gaining an insight of the participant’s behavior in a certain scenario.
A focus group is a pointed discussion with a group of participants that a moderator leads through a set of questions on a particular topic to obtain feedback (about users, products, concepts, prototypes, tasks, strategies, and environments) and insights to create thanks to the dynamic group dynamic. (Part of qualitative research)
It is a usability inspection method for computer software that helps to identify usability problems in the user interface (UI) design. It specifically involves evaluators examining the interface and judging its compliance with recognized usability principles (the "heuristics").
Named after British and American psychologists William Edmund Hick and Ray Hyman, describes the time it takes for a person to make a decision as a result of the possible choices he or she has: increasing the number of choices will increase the decision time logarithmically.
A multidisciplinary field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design.
They are intended to give anyone involved in the design and development of websites and applications a broad approach to inclusive design.
Structural design of shared information environments; the art and science of organizing and labelling websites, intranets, online communities and software to support usability and findability; and an emerging community of practice focused on bringing principles of design and architecture to the digital landscape.
Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know. Jakob's Law was coined by Jakob Nielsen, a User Advocate and principal of the Nielsen Norman Group which he co-founded with Dr. Donald A. Norman (former VP of research at Apple Computer).
Inspired by Lean and Agile development theories, Lean UX speeds up the UX process by putting less emphasis on deliverables and greater focus on the actual experience being designed.
The average person can only keep 7 (plus or minus 2) items in their working memory. In 1956, George Miller asserted that the span of immediate memory and absolute judgment were both limited to around 7 pieces of information. The main unit of information is the bit, the amount of data necessary to make a choice between two equally likely alternatives. Likewise, 4 bits of information is a decision between 16 binary alternatives (4 successive binary decisions). The point where confusion creates an incorrect judgment is the channel capacity.
Application vendors consider their mobile users as the number one priority in their development roadmap.
A mockup is a detailed static representation of the design that clearly displays the information structure, renders the content and demonstrates the basic functionality. A mockup is a prototype if it provides at least part of the functionality of a system and enables testing of a design.
Minimal Viable Product, is a version of a product that has the minimum amount of features but can be used for user testing or demonstration. This approach allows for a more elaborate, in-depth testing phase before its potential is determined.
An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.
A panel refers to a permanent sample of individuals, representative of a population, periodically questioned about their attitudes, habits, opinions or behaviours.
The Pareto principle states that, for many events, roughly 80% of the effects come from 20% of the causes. Its origins stem back to Vilfredo Pareto, an economist who noticed 80% of Italy’s land was owned by 20% of the population. Though it might seem vague, the 80/20 way of thinking can provide insightful and endlessly applicable analysis of lopsided systems, including user experience strategy.
Any task will inflate until all of the available time is spent. Articulated by Cyril Northcote Parkinson as part of the first sentence of a humorous essay published in The Economist in 1955 and since republished online, it was reprinted with other essays in the book Parkinson's Law: The Pursuit of Progress (London, John Murray, 1958). He derived the dictum from his extensive experience in the British Civil Service.
Is the characterisation of a user who represents a segment of your target audience. On a project you might create any number of personas to be representative of a range of user needs and desires. Contrary to archetypes, personas are mainly based on socio-demographic characteristics, rather than behavioural ones.
A rough guide for the layout of a website or app, giving an indication of the direction that the product is heading.
Research methodology based on understanding of behaviours, needs and perception of individuals. That's allowed through observation of individuals, or listening and interpretation of their answers and explanations. This methodology mainly replies to the questions "why" and "how". That includes for example indiviual interview, focus groups, ethnographic researches, or remote user tests.
A reserach methodology based on statistical data. We look at the individuals as a group, and not as an isolated person. That means an adequate number of individuals is required, and that the sample needs to be representative of the target. Individuals answer a survey, giving precise figures as results. These results mainly answer to what and who (vs why and how with qualitative research).
The proportion applied to some identified criteria in order to build a sample of indiviudals. Quotas can make a sample representative if they match to the proportions of the aimed population.
Reserach methodology set up by Ferpection through its platform. Users have access to missions to test services or products, online or offline. For each mission, they have several steps to follow and describe their experience pointing out positive and negative feedback. Each feedback is illustrated with a picture, a screenshot or a quick video.
A design approach that responds to the user’s behavior and environment based on screen size, platform and orientation. The practice consists of a mix of flexible grids and layouts, images and an intelligent use of CSS media queries.
A sample is a smaller, and more manageable group of people, coming from a larger population. It has to include the same main characteristics as the larger group. It can also be representative of this population, strictly speaking, by the quotas method.
The service blueprint is a technique originally used for service design and innovation, but has also found applications in diagnosing problems with operational efficiency. The service blueprint is an applied process chart which shows the service delivery process from the customer's perspective.
Closed and open-questions. Each question must be carefully written, and can be presented for example as semantic or numerical scales, items checklist, or fields to complete. Surveys are mainly used for quantitative research.
The System Usability Scale (SUS) provides a “quick and dirty”, reliable tool for measuring the usability. It consists of a 10 item questionnaire with five response options for respondents; from Strongly agree to Strongly disagree.
The target is the population you want to reach with a product, service or brand.
Tesler's Law, also known as The Law of Conservation of Complexity, states that for any system there is a certain amount of complexity which cannot be reduced. While working for Xerox PARC in the mid-1980s, Larry Tesler realized that the way users interact with applications was just as important as the application itself. The book Designing for Interaction by Dan Saffer, includes an interview with Larry Tesler that describes the law of conservation of complexity.
A file mapping the different tests to come to help the product development.
A usability technique for evaluating the findability of topics in a website. It is also known as reverse card sorting or card-based classification. A large website is typically organized into a hierarchy (a "tree") of topics and subtopics. Tree testing provides a way to measure how well users can find items in this hierarchy.
User Interface, in the industrial design field of human–computer interaction, is the space where interactions between humans and machines occur.
Is an important quality indicator for interactive IT products/systems. It refers to the degree to which products are effective, easy to use, easy to learn, efficient, fewer errors and satisfying to users. Usability is mainly about the functional part of the product. In a word, “Don’t make me think”.
User centered design (UCD) is an approach to designing a product or service (e.g. user interface design), in which the end user is placed in the center of the process. The primary concern of user-centered design are the targeted end users of the website or the application and which requirements these users will have. User-centered design ensures that the target users easily understand the user interface and find what they are looking for.
A UX evaluation method, through a 2-3 minutes survey developed by 3 German experts. The methode is introduced as a "fast and reliable questionnaire to measure the User Experience of interactive products on 6 scales: attractiveness, perspicuity, efficiency, dependability, stimulation, novelty."
Or customer experience : Refers to a person’s subjective feeling and attitudes about using a particular product or service, online or offline. It includes the functional scope, product and brand's perception, psychological expectations, and actual emotional feelings. These are indispensable parts of the user experience. It's important to think the user experience (or customer experience) in its entirety, considering every touchpoints between the user and the brand.
User flow is the path taken by a prototypical user on a website or app to complete a task. The user flow takes them from their entry point through a set of steps towards a successful outcome and final action, such as purchasing a product.
It's a qualitative research methodology, for which a moderator will talk with a single user. The objective is to have insights about its behaviour, expectations, perception about a defined topic. This can be purely exploratory or include a test of a product or sevice. Interviews can be done by phone, video call or in person.
A user journey is a sequence of steps a user takes to reach their goal when navigating a website. It is simply an experience a user has while interacting with software.
In agile modeling, user stories are one of the primary development artifacts for Scrum and Extreme Programming (XP) project teams. A user story is a very high-level definition of a requirement, containing just enough information so that the developers can produce a reasonable estimate of the effort to implement it.
The systematic investigation of users and their requirements, in order to add context and insight into the process of designing the user experience. In others words, it's asking your users to place them at the centre of your decision process. UX research is not a technical assessment, even though you may encounter some bugs to fix. UX research is not theoretical research either, as it focuses on finding detailed facts on pragmatic real-life experiences and not abstract principles or theories. It is “applied” research.
A rough guide for the layout of a website or app, either done with pen and paper or with wireframing software.
