- - - - -If its objectively pleasing it is more effective to the user
        -classic design often has cultural influence
- - - - is when only one for a few specialist items are required
    - - a set quantity of a product are produced to order
    - - aims to deliver products that best meet customer needs with near mass production efficiency.
- - - - A natural resource that can replenish with the passage of time or does not abate at all
    - - A resource that doesn't renew itself at a sufficient rate for sustainable economic extraction
    - - A natural resource which has been identified in terms of quantity and quality
    - - A resource which can be replenished over time, for example wood
  - - - Can reduce or eliminate materials directed to landfill.
    - - The reduction of total material and energy throughput of any product and service, and thus the limitation of it's environmental impacts
  - - - The processes of separating the component parts of a product to recover the parts and materials
    - - An economy in which resources remain in use for as long as possible.
  - - - Embodied energy is the total energy required to produce a product
    - - An electrical supply distribution network that can be national or international
    - - The ability of an individual to use devices to create small amounts of energy to run low-energy products
  - - - Products, services or processes that reduce waste and require minimum amount of non-renewable resources
    - - Technology that is used to reduce pollutants and waste at the end of a process
  - - - Designing in a way that takes account of the environmental impact of the product throughout its life
    - - Laws and regulations that are based and sustainability principles, followed by designers and manufacturers when creating green products
    - - The avoidance or minimisation of producing waste in relation to the production, use and disposal of a product
- - - - Communication with client and users
      - Communication with team members
    - - Lacks detail
      - Can be misinterpreted
  - - - 2-D modelling is mostly diagramatic, and it conveys what may happen in reality.
    - - A 3-D physical model is a tactile representation of an object. These may includes prototypes or clay models
    - - The plans are drawn at a specific ratio relative to the actual size of the place or object
    - - A sketch is a spontaneous representation of ideas on paper without the use of technical aids
      - Formal drawing techniques tends to be used in the development phase of a design process
    - - An assembly drawings shows how parts of a products fit together
  - - - Physical models allow the user to better understand the problem
    - - Aesthetic models are made only for show and they are not made to be used. They are only for visual.

    - - Is the first idea
  - - - Involves the use of surface and solid modelling to develop photo-realistic interactive models
    - - Requires the designer to draw parts individually and then assemble them together
  - - - Is also known as an optical fabrication, the quality of a product it depends on the quality of the SLA machine
    - - take the sliced CAD data from a 3D model
- - - - Refers to measurements taken while the subject is in a fixed or standard position, for example; height, arm length
    - - Refers to measurements taken during physical activities, for example: range of upper body movements
    - - A selection of sizes a product is made in that caters for the majority of the market
    - - The ability of a product to be changed in size, commonly used to increase the range of percentiles that a product is appropriate for
  - - - Human factor data related to physical characteristics used to optimise the user's safety, health, comfort and performance
