In business, a client is a person or organisation that wants a product manufactured, eg a retailer.
Collaboration
When two or more people work together to achieve a goal.
Component
A part that when put together makes a product.
Computer Aided Design (CAD)
The process of creating a 2D or 3D design using computer software.
Computer Aided Manufacture (CAM)
The manufacture of a part or product from a computer aided design (CAD) using computer-controlled machinery, such as a 3D printer.
Construction
How an item is put together.
Construction lines
Lightly drawn lines that aid the accurate placement of permanent lines in a diagram.
Coordinates
X, Y and Z values that represent a known point in space.
Design brief
A set of instructions given to a designer by a client.
Design specification
Document containing details of a product's required characteristics, and all the processes, materials and other information needed to design the product.
Design strategy
A series of steps used to plan a design process.
Dimensions
Sizes and measurements.
Electrical components
Something you solder into a circuit, eg a resistor or a diode.
Elevation
A particular side.
Ergonomics
The science of designing the product to fit the user, or the job to fit the worker.
Evaluate
To judge the quality and performance of a product.
Exploded diagram
A 3D view of how each part of a design fits together.
First angle projection
Orthographic drawing for manufacturing.
Fixated
To become stuck on a single point or idea.
Flowchart
Also known as a flow diagram. A diagram that shows the step-by-step flow of an algorithm.
Formal drawing
A drawing using techniques such as third or first angle with dimensions.
Freehand sketching
Drawing without guides such as rulers.
Function
A group of instructions, also known as a procedure
Functioning
Working.
Garment
An item of clothing.
Horizontal
Parallel to the ground.
Hypothesis
An initial guess to a question which is then supported or rejected depending on the evidence collected.
Innovative
An innovative person creates new ideas or methods of doing something. An innovative product introduces new ideas or methods.
input, process and output
The series of events that makes a system.
interior designer
A professional who specialises in the design of room layout.
isometric drawing
A 3D representation of a design with no vanishing points.
Iteration
Repeating the steps in the design process to get closer to the desired result.
iterative design
A cyclic design process of modelling and testing to achieve gradual improvements to the design.
laser cutter
A machine that uses a laser beam to vaporise material and cut out shapes very accurately.

The market for goods that are produced in large numbers.
Modelling
Creating a model of a product.
Modification
A change made to improve something.

A number of parts working together to fulfil a complete function.
Systems approach
The use of block diagrams to clearly show different inputs, processes and outputs to and from a system.
Systems diagram
A block diagram that shows the inputs, processes and outputs of a system.
Target market

Third angle projection
Orthographic drawing for manufacturing.
Time lapse

To scale
Having a fixed relationship to the actual dimensions of an object. The relationship is usually stated as a ratio, eg. 25:1.
Toile
An early model of a textiles product.
