Q

Iterative design process

A

Using a cyclic sequence of stages required to refine a design

Research -> ideate -> prototype -> test _^

Q

User-centred design

A
  • Aims to improve users’ experience of using products
  • There is an international usability standard, ISO 13407:
    • Take full account of users, the task performed and the relevant
    environment
    • Involves users during design and development
    • Refined by user-centred evaluation
    • Considers the whole user experience

Q

Methods used to achieve UCD standards

A
  • Apply ergonomic principles for ease of use and comfort
  • Use anthropometric data to ensure a good fit
  • Observe people using products
  • Organise focus groups to solve problems with existing products
  • Gain an understanding of how users interact with products
  • Improve the user experience

Q

Designing to meet needs, wants or values

A

Consider the:
Physical needs - needs of children are very different to the elderly
Emotional needs - understanding what people like, matching their aspirations
Intellectual needs - for example, small children are attracted to bright colours

Q

Primary investigate techniques

A
  • Market research questionnaires and surveys
  • Interviewing potential users to investigate their wants or needs
  • Focus groups
  • Human factors:
    • Empathic research
    • the designer experiences users’ limitations, e.g. Lack of mobility
  • Anthropometric data is obtained
  • Ergonomics can be improved by getting customers to use the product
  • Product analysis:
    • disassembly of existing products
    • practical testing of components

Q

Secondary investigative techniques

A

Using external resources such as research journals, online and books

Could consider:
• Style influences of designers and movements
• Identifications of suitable materials, components, and manufacturing
methods
• Relevant anthropometric data

Q

Planning, manufacture and evaluation of a prototype

A
  • Creating a step-by-step, detailed plan of prototype manufacture considering:
    • Tools
    • QA
    • QC
  • Carry out hand, machine or rapid prototyping methods as required
  • Test and evaluate prototype with involvement of consumers
  • Carry out iterative improvements to optimise the design
