The User Experience (UX) Glossary

UX is an abbreviation for User Experience. A UX Architect creates enjoyable user experiences by applying reusable design patterns that have successfully validated with users. One of the concepts that I leverage as a UX Architect is that there is a design language that can be used to describe everything. In order to level set, it is important to have a shared vocabulary so you can easily share ideas and concepts, for this purpose I have put together a UX Glossary that can be referenced when reading posts on this site.

A

Affordance – When a user interface control/component behaves as its appearance suggests. Assumption A supposition or belief in something without any proof. To believe in something before it happens, even if uncertain. Auto-complete A software feature that helps finish what a user is typing by predicting what the user wants to input based on previous or popular entries.

B

BDUF (Big Design Upfront) – The expectation that UI Design of a release to be completed, perfected and documented in detail before writing source code. It is often associated with the waterfall model of software development. Backlog In software development, a backlog is an accumulation of uncompleted requirements (user stories).

Branding– branding is a promise that is made to the user, and effective branding is fulfilling the promise. It contains  the message that is being delivered to the user about the product they are using.

C

Card Sorting –  A method that is used to check the intuitiveness and usability of user interface information architecture (labels, nomenclature, navigation, data structure). Used when there is an immature or unestablished navigation structure. Case Study Analysis of a group, person or event to explore causation or determine underlying principles.

Clickability Cues – A visual indication that a given word or item in the user interface is clickable or selectable.

Clustering – Patterns which emerge from the analysis and synthesis of large sets of data which help the design team select appropriate design solutions.

Cognitive Design Principles – Design principles related to comprehension of object behaviors, interpreting complexity, distinguishing functions, and switching modes or changing focus within the user interface.

Competitor Analysis – An assessment of the relative strengths or weaknesses of competitor products or organizations.

Context Scenario – Used to explore, at a high-level, how the user interface can best serve the needs of the persona. Also known as “day-in-the-life” scenarios. Created before any design is performed and are written from the perspective of the persona and focus on human activities, perceptions, and desires. Content and context for the scenario is derived from data collected during user research.

Contextual Inquiry – The best way to understand the users’ work practices. During Contextual Inquiry the person doing the discovery work observers the user in their natural environment, making note of their surroundings, and their work processes. This is the most unadulterated way to collect user data.

Convergent Thinking – The ability to narrow the number of possible solutions to a problem by applying logic and knowledge.

Customer visits –  These are sessions where one goes on site to gather as much user data as possible, this can be done through contextual inquiry, and discovery interviews.

D

Debrief – A meeting taking place between design team and occasionally with stakeholders at the end of a research session. In it, significant findings, conclusions are presented by the research facilitator(s) and discussed collectively with the team.

Design Brief – A comprehensive written document for a design project distributed to designers which represents the business need for the design. The document is focused on the desired results of design – not aesthetics.

Design Hypothesis – Also known as a “presumptive design”. A prediction that a specific design will result in a specific outcome. A design hypothesis must 1.Identify the design’s theory, 2.provide a concise description of the design preferably in the form of a low-fidelity model, 3.state what the design must achieve in a verifiable fashion, and 4.clearly identify critical assumptions that support the hypothesis. (See “Hypothesis”)

Design Iteration – Refinement of small yet significant changes made to a design in order to enhance the idea and increase the effectiveness of its ability to solve users problem(s).

Design Pattern – User interface design pattern is a recurring and general reusable solution to solve a common design problem within a given context in software design.

Design Principles – Broadly applicable guidelines that reduce work for the user.

Design Thinking – Ways of thinking, conceptualizing, imagining, and envisioning solutions to problems that (i) redefine the fundamental challenge or task at hand, (ii) develop multiple possible options and solutions in parallel, and (iii) prioritize and select those which are likely to achieve the greatest benefits in terms of, for example, impact, viability, cost.

Disruptive Innovation – An innovation that helps create a new market and value network, and eventually disrupts an existing market and value network (over a few years or decades), displacing an earlier technology.

Direct User Data – Feedback that comes from the face-to-face research method such as a one on one interview or focus group.

Divergent Thinking – The ability to develop original and unique ideas and to envision multiple solutions to a problem.

Drivers – Drivers are the knowledge and conditions that are the catalyst for the tasks/activities for which the design was created. Knowledge and conditions can include such market forces, business cost reduction, etc.

E

The goal is to create a shared understanding of the customer.
