Design for Six Sigma Deployment 121

Stage 0: Impetus/ideation
• New technology, new ideas, competition lead to new product/service possibilities
• Several product/service options are developed for those possibilities

Stage 1: Customer and business requirements study
• Identification of customer needs and wants
• Translation of voice of customer into functional and measurable product/service
requirements
• Business feasibility study

Stage 2: Concept development
• High level concept: general purpose, market position, value proposition
• Product definition: base level functional requirement
• Design concept generation, evaluation, and selection
• System/architect/organization design
• Modeling, simulation, initial design on computer or paper T T

Stage 3: Product/service design/prototyping
• Generate exact detailed functional requirements 1 2
• Develop actual implementation to satisfy functional requirements, i.e., design
parameters D D
• Build prototypes F F
