Market Assessment

  • is a systematic activity:
  • Identification of the market need → sale of product to meet that need.
  • Product, Process, People, Organization, etc.
  • Design Core
    • Market Analysis
    • Specification
    • Concept Design
    • Detailed Design
    • Manufacturing
    • Sales
  • Product Design Specification (PDS)
    • Envelopes all stages of the design core

Market Assessment

  • SPECIFICATION
  • Product Design Specification (PDS)
  • Develop Specification (8 stages)
  • Construct customer needs matrix
  • Develop performance measures
  • Cross correlate (needs-measures matrix)
  • Construct competitive benchmark chart to assess market position (based on customer needs and performance measures)
  • Define an initial set of target specifications
  • Carry out engineering design analysis to assess technical feasibility
  • Develop a bill of materials for initial cost assessment
  • Redefine the set of specifications
