Where can I find a good and detailed information about Design for DMADV?

Hi Christian, The two methods are matching, the difference is what they target- the DMAIC targets the business process/es in order to improve it/them, while DMADV’s goal is to improve customer needs and meet customer requirements. That is why if you apply the Lean 5 Lenses or 4 Pillars you always start with Voice of the Customer ( the customer can be internal/external).No matter the cycle after you have covered the customer needs you follow with Define, Measure, Analyse phase. Then, Improve (DMAIC) - is designing the new process, while Design( DMADV) is designing the process that matches the customer needs/requirements. In the Control phase (DMAIC) you continuously improve the process , while Verify (DMADV) is the sense check with the customer is that product/service what he/she expects. No matter which cycle methodology you will use- what you need to identify are the Critical to Quality for the customer factors and that is when your journey starts.

Hi Christian, 

The main rule is if the SIPOC (Supplier-Input-Process-Outcome-Customer) is changing, then you need DMADV. 

Have you ever actually considered do you need DMADV or you can use the DMAIC?

If your answer is still yes - then you need to start analysing the external data on the drivers. That is a forward-focus thinking.

I have tried to summarise below the differences. A rule of thumb is DMADV focuses on drivers, while DMAIC focuses on causes.

D- Organisation                             D- Organisation

M- Symptoms                                M- Requirements

A- Causes                                         A- Drivers

I - Improve                                       D- Design

C- Implement/Sustain               V- Test/Scale-up/Implement/Sustain

The questions below can help you with your actions:

• Do I need to create a brand new process?
• Is the current process too broken?
• Did the current process reach its best performance?
• Is there a risk of high-cost failure?

Answer to yourself do you need to do it from scratch or you can copy and paste a process and make iterations. 

If after all of the above , still the answer is - you need DMADV, then focus on hypothesis rather than assumptions, because you can test the hypothesis.

Thanks,

Kate
