Design Strategies

• Iterative design


  A cyclic or repeated process of designing, prototyping, testing, evaluating, and redesigning
• Iterative design


  • Allows issues to be realized and resolved earlier in the process
  • Creating and testing prototypes can be time-consuming and expensive
• User-centered design


  The needs and wants of the end user are considered at each stage of the design process
• User-centered design


  • Gives the end user a greater sense of ownership through their contributions
  • Design can become too biased or focused on the requirements of one particular end user
• Systems thinking


  The design process is split into subsections of input, process, and output
• Systems thinking


  • Allows errors or faults to be identified more quickly by breaking the system down
  • Can lead to the use of unnecessary components, resulting in extra costs and bulkier systems
