Design Thinking Vocabulary in English

Prototyping is the process of creating simple, tangible representations of a design concept so it can be visualised, tested, and refined. Prototypes range from paper sketches to interactive digital mockups. The key principle is to build fast and cheap, making it acceptable to throw early versions away. Prototyping externalises thinking, enables concrete feedback from users, and reveals flaws that would be far more costly to fix in a finished product. Teams typically create multiple prototypes and iterate based on what they learn.

Ideation is the creative process of generating a wide range of ideas in response to a defined problem. In design thinking it typically follows the Empathise and Define stages. Common ideation techniques include brainstorming, brainwriting, mind mapping, and SCAMPER. The goal is to produce quantity and variety, suspending judgment until later stages when ideas are evaluated and selected. The most important rule of ideation is to defer judgment so that wild ideas are not dismissed before their potential is understood.

An empathy map is a visual tool used in design thinking to build a deeper understanding of a user's experience. It typically captures what the user says, thinks, does, and feels in relation to a given situation or problem. Empathy maps are created from research data — observations, interviews, and user testing — and help design teams develop genuine insights about user needs, motivations, and frustrations. They are useful for building consensus within teams about who the user is and what really matters to them.

User-centred design (UCD) is an approach to designing products, services, and systems in which the needs, goals, and limitations of the end user receive extensive attention at each stage. It contrasts with technology-centred or business-centred approaches that prioritise technical capabilities or commercial goals. UCD involves extensive research, iterative testing with real users, and ongoing refinement based on feedback. The principle is that understanding users deeply leads to solutions that are more effective, efficient, satisfying, and accessible.

A persona is a fictional but research-based representation of a target user, created to help designers understand and empathise with the people they are designing for. Personas include name, age, occupation, goals, frustrations, and preferences. They are based on patterns identified from user research rather than stereotypes. Personas are used throughout the design process to keep the team focused on user needs and to evaluate design decisions from the user's perspective. A design team might create two to five personas to represent different user types.

Iteration in design refers to the cycle of building, testing, learning, and refining that is repeated multiple times to progressively improve a design. Each iteration produces a version that is tested with users, and insights feed directly into the next version. Design thinking embraces iteration because early ideas are rarely optimal — real improvement comes from learning through experimentation. Iteration reduces the risk of investing heavily in a solution that does not meet user needs by catching problems early and cheaply.

A point of view (POV) statement is a precise problem statement defining who the user is, what they need, and why they need it, synthesised from research insights. It frames the design challenge in a human-centred way. A typical POV statement follows: ‘[User] needs to [need] because [insight].’ A good POV statement is specific enough to guide ideation without being so narrow that it limits creative thinking, and serves as a reference point to ensure solutions remain grounded in real user needs throughout the process.

Divergent thinking involves generating as many ideas as possible, exploring multiple directions without judgment — it is the mode associated with brainstorming and ideation. Convergent thinking involves evaluating, selecting, and refining ideas to move toward a single solution. Design thinking deliberately alternates between these two modes at each stage: diverging to explore possibilities and converging to make decisions. Effective design teams manage the transition between modes, knowing when to open up and when to narrow down.

Start with the five core stages: Empathise, Define, Ideate, Prototype, and Test. Then build vocabulary around tools and methods: empathy maps, personas, journey maps, POV statements, wireframes, and A/B testing. Reading IDEO's online resources and the Stanford d.school website provides excellent exposure to design thinking language in authentic contexts. Watching TED Talks by designers such as Tim Brown also builds listening vocabulary. Practising design sprints — structured five-day design processes — is the most effective way to internalise design thinking vocabulary through active use.
