Design For Six Sigma Basics

What if your business doesn’t have a particular service or product that your customers have been asking for? Completely modifying an existing product probably still won’t meet your customer’s requirements. That’s when Design For Six Sigma (DFSS) comes in very handy.

When To Use DMADV for Design For Six Sigma

  • Creating a brand new product rather than fixing the existing product.
  • When improving an existing process won’t meet the customer’s requirements.
  • The timing to offer an entirely new product or service opens up to do so.

QFD (Quality Function Deployment): Developed in Japan, it helps transform VOC (voice of the customer) into characteristics for a product.
Risk Assessment: The determination of quantitative or qualitative amount of risk related to the product or situation.
Scorecards (Raws, Process, and Product): It is the scorecard that can be used to assess the product and process performance so customer requirements are met in all of the stages in the design process.
