Design for Six Sigma DfSS

You are probably aware of our Lean Six Sigma Masterclass – designed to get you a Lean Six Sigma Green Belt Certificate – but what about if you need to develop NEW processes, products, and services?

Well, luckily Projex Academy has a Masterclass that teaches you how to master Design For Six Sigma (DfSS) using the DMADV Method.

These video modules are a companion Masterclass to our Projex Academy Lean Six Sigma Masterclass:

  • Module 1 DMAIC AND DMADV
  • Module 2 DMADV DEFINE AND ANALYZE PHASES
  • Module 3 DMADV DESIGN AND VERIFY PHASES
  • Module 4 THE HOUSE OF QUALITY (QFD) Part ONE
  • Module 5 THE HOUSE OF QUALITY (QFD) Part TWO
  • Module 6 QFD AND THE PUGH MATRIX
Design For Six Sigma Dfss

Lean Six Sigma used the DMAIC Method, whereas DfSS uses the DMADV Method – Define, Measure, Analyse, Design, and Verify

DMAIC is used to improve existing processes, but sometimes the process does not exist and you need to create one, or perhaps for new services or products

It may be that your current process is so poor that scrapping it and starting again makes more sense!

DMADV will help introduce new products and services quickly and to a consistently high standard

When redesigning a process we focus on the customer, when designing a new service or product there may not be a customer yet, so we focus on the demands of the (potential) marketplace

Where the customer is involved, this means both end-user customers and internal business stakeholders and users
Customer requirements and the resulting Critical To Quality (CTQ) requirements are established early on and the DMADV framework ensures that these requirements are satisfied in the final product, service, or process

As with DMAIC, we managed by facts and not speculation to ensure that new designs reflect customer CTQs and provide real value to the customers.

DMADV projects are more resource-hungry than DMAIC projects in terms of people, IT involvement, and cost
Despite these higher costs and risks, DMADV projects bring higher rewards

In large organizations using Lean Six Sigma, 20 DMAIC projects will likely be carried out for every DMADV project

There are likely to be many lean projects, a moderate number of DMAIC projects, and a few DfSS projects as the organization gradually reduces rework and waste, improving process flow and reducing cycle times.

Boosting the core fundamentals of L6S 

  • DMAIC
  • Lean Principles
  • Six Sigma Process
  • Kanban
  • Just In Time (JIT)
  • Heijunka Leveling, Sequencing and Standardizing
  • Takt Time
  • … and much much more

Lean Six Sigma takes the features of Lean ( speed), and combines them with Six Sigma (stability and accuracy). This Lean Six Sigma Green Belt Masters Series will teach you how to streamline processes, improve business performance and supercharge your career
