DFSS

Design for Six Sigma

The Six Sigma process that gets all the press is primarily centred around manufacturing or transactional processes to ensure that a current design or process is made or performed in the best possible way.

Design for Six Sigma (DFSS) is a process to ensure that the design can actually be made to 6-Sigma standards. After all you can tweak the manufacturing process all you like, but if the design fundamentally is not up to it, then it will all be a waste of time.

The process that is most often used in traditional (manufacturing or transactional) Six Sigma is called DMAIC (Define, Measure, Analyse, Improve, Control). A different approach is called for in DFSS; Define, Measure, Analyse, Design, Verify, or DMADV for short.

Then there a number of tools that can be used to make sure that the design is going to be suitable

  • To meet the customer’s needs (QFD)
  • To be manufacturable, at the quality targets specified (DFMA, Tolerance Analysis, DoE)
  • To be robust and avoid failure (FMEA, FEA)
  • To meet other requirements, such as serviceability, environmental requirements etc. (DFX)

Perhaps you already have a Six Sigma process in your manufacturing plant, but you have reached the limit of what you can achieve with your current designs. Or maybe you just want to make your designs better. Whatever the reason contact us to discuss how we could help you to design more capable products.
