Product Design and the Double Diamond Process

Comprehensive vocabulary flashcards covering the Double Diamond design process, command terms, design factors (FUN TEAM P), research methodologies, ergonomics, and inclusive design principles.

Double Diamond Design Process

A structured design methodology featuring four distinct phases across two diamonds: Discover (investigating), Define, Develop (generating and designing), and Deliver (producing and implementing), underpinned by ongoing evaluation, planning, and managing.

Investigating and Defining

The first phase of the Double Diamond process comprising Discover (divergent research to uncover needs or opportunities) and Define (convergent thinking to clarify parameters in a written design brief and evaluation criteria).

Generating and Designing

The second phase of the Double Diamond process (Develop) involving divergent thinking where concepts are suggested, explored, sketched, trialled, modelled, prototyped, and refined.

Producing and Implementing

The final phase of the Double Diamond process (Deliver) involving convergent thinking to prepare working drawings and scheduled production plans, manufacture the solution, perform quality checks, and carry out testing and evaluation.

Divergent Thinking

A creative thinking mode that explores possibilities, asks questions, takes risks, and broadens concepts through activities such as brainstorming, mind mapping, and open-ended research.

Convergent Thinking

A critical thinking mode focused on analysing information, narrowing down options, critiquing results, and making decisions to solve problems and plan production.

Primary Research

First-hand information, surveys, or practical investigations carried out personally by the researcher.

Secondary Research

Information gathered from existing sources conducted by others, such as books, catalogues, or the internet.

Quantitative Research

Research data that can be measured, quantified, and explained using numbers.

Qualitative Research

Research data that is highly detailed, descriptive, individualised, and focused on characteristics.

Design Brief

A written statement that identifies a need or opportunity, outlines an end-user profile, and specifies the scope of the project, including constraints and considerations.

Constraint

A mandatory, non-negotiable 'must have' condition or boundary in a design project, such as budget, timeframe, or specific dimensions.

Consideration

A flexible design aspect that is open to further discussion, exploration, and research rather than being a rigid requirement.

Evaluation Criteria

Clear, product-specific standards drawn directly from the design brief (often formulated as questions) against which a finished product or concept is tested and judged.

Prototype

A preliminary physical model or virtual 3D CAD representation of a product—often scaled or made from temporary materials—used to test visual and functional aspects and identify areas for refinement.

FUN TEAM P

An acronym representing the key factors that influence design: Function, User (end users), Need or opportunity, Technologies, Ethical considerations, Aesthetics, Market opportunities, and Product life cycle.

Universal Design

The design approach aimed at making products and environments accessible and usable to everyone in society, governed by seven key principles.

Accessibility

Designing products to suit users in relation to their abilities and capabilities, particularly in digital products and clothing, so that individuals with limitations can use them effectively.

Equity (in Design)

A design principle ensuring that a product is useful and appealing to people with diverse abilities, providing equal usability.

Ergonomics

The study of how products and environments suit the human body to optimize comfort, efficiency, and safety while reducing injury, strain, and fatigue.

Anthropometric Data

Standardized physical measurements of the human body collected from across populations and averaged to inform product dimensions.

Demographic

Specific identifiable groups or categories of people within a broader population, segmented by factors such as age, gender, or income.

Aesthetics

A product's visual form, appearance, and sensory feel, established through design elements (such as line, shape, colour, texture) and design principles (such as balance, proportion, rhythm, and contrast).

Product Life Cycle

The complete sequence of stages in a product's lifespan, encompassing raw material extraction, manufacturing, distribution, consumer use, and ultimate disposal or recycling.

Ethical Research Methods

Guidelines for conducting research responsibly, including safeguarding participant privacy, obtaining informed and voluntary consent, being transparent, presenting data honestly, and ensuring no harm.

Connection to Country (Design Influence)

An Indigenous design principle where products and tools (such as eel traps and coolamons) are informed by a deep relationship to the land, local natural materials, and sustainable contextual practices.

Discover Stage (Double Diamond)

The initial divergent stage of the first diamond where designers conduct open-ended research, observe user needs, and explore market opportunities.

Define Stage (Double Diamond)

The convergent stage of the first diamond where exploratory research findings are synthesised to establish clear project boundaries, the design brief, and evaluation criteria.

Develop Stage (Double Diamond)

The divergent stage of the second diamond where multiple concepts are sketched, trialled, 3D modelled, and prototyped to explore potential solutions.

Deliver Stage (Double Diamond)

The final convergent stage of the second diamond where working drawings are finalised, the product is manufactured, and testing against criteria is conducted.

Scheduled Production Plan

A detailed sequence and timeline prepared during the Deliver phase to organise materials, tools, and processes for safe, efficient, and cost-effective production.

Production Journal

An ongoing record maintained during the producing and implementing phase to document daily progress, record manufacturing modifications, and monitor quality control.

Planning and Managing (Double Diamond)

The foundational ongoing process running beneath both diamonds that coordinates time, budgets, materials, safety, and risk throughout the entire design cycle.
