Robust Concepts
• Selecting the concept that
best satisfies the design intent
• Selection may be an iterative
process.
• Selection is a narrowing
process, not a competition
between solutions.
Key ConceptsKey Concepts Value/BenefitValue/Benefit
• Selection should be based on
VOC and business needs.
• MUST follow a structured
selection process to ensures
that:
• Customer needs drive
process
• All criteria are considered
• Choices are documented
• Choices can be defended
later in the design cycle
• Process immune from
influence of champion and
other stakeholders
