iterative design process

• What is the purpose of iterative design?

  To improve the design of a product
• How does iterative design work?

  It is cyclic until final design is agreed
• What are the aims of the design strategy in iterative design?

  • Produce an engineering design specification
  • Generate design ideas through sketching and modelling
• What is a design brief?

  A document outlining product requirements
• Why is the design brief important?

  It details problems to solve for success
• What does a designer analyze in a design brief?

  • What needs to be designed
  • Product usage
  • Target audience
  • Sales location
  • Usage location
  • Prototype deadlines
• Why do engineers disassemble products?

  To understand how a product works
• What do engineers check during product disassembly?

  • Assembly methods
  • Materials used
  • Production methods
  • Component functions
  • Maintenance issues
• What is anthropometric data?

  The study of human body measurements
• What percentiles do designers focus on in anthropometric data?

  5th to 95th percentile of measurements
• Why do designers use anthropometric data?

  To cater to 90% of the population
• What are some methods of research in design?

  • Focus groups
  • Interviews
  • Observations
  • Product analysis
  • Surveys
  • Industrial visits
  • Internet
  • TV programmes
  • Databases
  • Textbooks
  • Newspapers
• What is the difference between primary and secondary research?

  • Primary research: Carried out by you
  • Secondary research: Carried out by someone else
