Design for Six Sigma

Design for Six Sigma (DFSS)

Difference Six Sigma and Design for Six Sigma (DFSS)
Design for Six Sigma (DFSS) is a product development methodology that helps developers develop competitive products or processes.
While classic Six Sigma is a reactive method for improving existing processes, Design for Six Sigma aims to make products and processes error-free right from the start. The procedure can be classified as a methodology of both product development and quality management.
Design for Six Sigma is thus a key success factor in the development of the right design of design and process. 


The DFSS-Logic: DMADV and IDOV
As with a traditional Six Sigma project, DFSS projects follow a systematic and logical sequence of steps. Design for Six Sigma projects follow the DMADV (Define - Measure - Analysis - Design - Verify) or IDOV (Identify - Design - Optimize - Verify) process.
 
Identify Phase
Scope and objectives of the development project are defined in the Define phase. Great emphasis is placed on raising the customer's requirements, understanding them and deriving clear requirements. The tools used here are Voice of the Customer (VOC), Requirements Development and Quality Function Deployment (QFD). 
Design Phase
In the design phase, different concepts are developed in the team (use of creativity techniques such as TRIZ) and systematically evaluated and selected (e.g. using Pugh Matrix).
Optimize Phase
In the Optimize phase, the selected concept is preventively optimized. Using statistical methods, data are analyzed, the relevant factors are identified by means of the Ishikawa diagram, and physical interactions are formulated. Subsequently, these are examined or confirmed by means of specific experiments (DOE) or simulations. Taking into account aspects of freedom from errors (FMEA), reliability (Design for Reliability) and robustness (Robust Design), the design parameters are finally determined. At the same time, the manufacturing process is defined at this stage. One tool used for this purpose is DFMA - Design for Manufacturing and Assembly. 
Verify Phase
In the Verfiy phase the efficiency of design and process is checked. Lifetime tests and process capability analyzes are used as tools here.
 
Design for Six Sigma (DFSS) Training
As absolute experts in this field, we train you to become a state-recognized Six Sigma Green Belt or Six Sigma Black Belt. In the case of Six Sigma courses, the focus is on the application in a specific project by each participant, which guarantees not only sound training but also proven benefits for your company at the same time. Practical exercises train Design for Six Sigma tools and ensure successful application in the company.
