Its a five step process for Six Sigma design for new products. Its useful when product or process is not in existence and one needs to be developed.

  1. Design : Define project goals and deliverables
  2. Measure : Measure customer needs and specifications
  3. Analyze : Analyze process options to meet customer needs.
  4. Design : Develop process details to meet customer needs
  5. Verify: Verify the design performance and ability to meet customer needs.

With DMAIC the six sigma analyst takes an existing process and follows a series of steps to improve its current state.

IDOV (Identify, Design, Optimize and Validate) quantifies the steps necessary to achieve six sigma quality in new products and processes.

Four step IDOV Model:

  • Identify: Overall product requirements are identified. Quantified customer information (customer feedback) becomes first set for CTQ. Technical requirements, performance targets and specifications (Use a team charter, QFD, FMEA and Benchmarking)
  • Design:Overall layout and geometry of product is developed.  Tools used typically are
    • DOE (Design of Experiments)
    • PQS (Product Quality Scorecards) are defined
    • Finite Element Analysis (FEA)
    • Computational Fluid Dynamics (CFD)
    • Statistical Inference (ANOVA)
  • Optimize:  Capability analysis for each component and sub-component.
  • Validate: Test and validate the design.
