The quest was defined by people like Shewhart and Taylor in the early 20th century, and hasn’t stopped as theories and methods for improvement are posited, reviewed, tested, and implemented. One of the most influential methods expounded in the last 35 years is Six Sigma. Originally formulated in manufacturing, the methodology is now practiced in fields such as healthcare and finance, in Fortune 500 companies all over the world. The design phase involves developing concepts, creating prototypes, and refining the design based on the customer requirements and data analysis. Robust design methodologies are used to ensure that the design is reliable, manufacturable, and meets all specifications.
IDDOV: (Identity, Define, Develop, Optimize, And Verify).
The intention of Design for Six Sigma is to bring such new products and/or services to market with a process performance of around 4.5 sigmas or better, for every customer requirement. This implies an ability to understand the customer needs and to design and implement the new offering with a reliability of delivery before launch rather than after. This popular methodology, which gained a foothold in American business in the 1980s, is now a worldwide practice. Proponents of Six Sigma tout its advantages, including reduced waste, improved understanding of customer requirements, reduced production time, and a cost savings of up to 50 percent. In the measurement phase, data is collected to establish baseline performance and evaluate the existing process capabilities.
How to Implement Design for Six Sigma (DFSS)
The Design for Six Sigma (DFSS) black belt table process seems to be implemented differently by each business or organization. All the methods seem to focus on understanding customer needs and applying that information to product and process designs. To ensure that the entire product is considered, the DFSS team needs to be cross-functional.

Finally, it may be helpful to use a DFSS scorecard to measure the product’s success from start to finish. This way, project teams can determine if the results meet the quality target. Failure Modes and Effect Analysis (FMEA) – Identify potential failures in the product design and manufacturing process and develop controls to minimize or correct them. In that case, they need to use DFSS because no matter the gains made in DMAIC, a 6 Sigma performance capability requires near perfection. Remember that not all businesses need to perform at a 6 Sigma Level due to certain diminishing returns. For example, we can all agree that we want commercial airplanes (that cost millions of dollars to build) built to the highest quality possible.

They will implement DFSS according to their business needs, structure, industry, and culture. In the current global marketplace, competition for products and services has never been higher. Therefore, many manufacturing companies are continually striving to introduce completely new products or break into new markets. Sometimes the products meet the consumer’s needs and expectations and sometimes they don’t. The company will usually redesign the product, sometimes developing and testing multiple iterations prior to re-introducing the product to market. It would be much more beneficial if the product met the actual needs and expectations of the customer, with a higher level of product quality the first time.
Similarities with other methods
Oftentimes this leads to companies spending LOTS of money designing something in trial and error to build the best characteristics for this new good. But with DFSS, customer needs are built into the product’s design up front. This idea would set the stage for the Six Sigma method, completely changing the future of quality control.
The Design for Six Sigma (DFSS) degree training program for black belts, focuses on doing additional work upfront to ensure that you fully understand your customer’s expectations and needs before the design is completed. You can improve the quality of new table products and processes by using a Design for Six Sigma method. When your company designs a new product or process from the ground up it requires a sizable amount of time and resources. Many products today are highly complex, providing multiple opportunities for things to go wrong. If your design does not meet the customer’s actual wants and expectations or your product does not provide the value the customer is willing to pay for, the product sales will suffer.
This model gave Motorola a working, statistical method to analyze their processes, identify faults, and make ongoing enhancements. Similar to Shewhart, Smith devised a threshold of tolerance for defects, but Smith’s was much more specific. His threshold was measured in defects per 1 million opportunities for a defect to occur (DPMO).
This is typically achieved by conducting data analysis to pre-designed template match tests via a techno-functional approach using multilevel quality function deployment on the data-set. It is often seen that[weasel words] the tools used for DFSS techniques vary widely from those used for DMAIC Six Sigma. While it can be claimed that[weasel words] two processes are similar, in practice the working medium differs enough so that DFSS requires different tool sets in order to perform its design tasks. But, while Walter Shewhart provided the statistical framework that enabled the creation of Six Sigma, he didn’t formally create the management methodology itself.
A Kano Model is a great tool to measure and rank customer needs (must-haves) and wants (exciter) features.
However, a company producing low pencils, a low-cost good, can be successful at a 4 Sigma Level with a DPMO of 6,210. Therefore, the MEASURE phase is best defined in terms of customer needs and wants, then translating them into measurable design requirements. Like DMAIC, here you want to determine the needs and specifications for your new process. However, in DMAIC, MEASURE involves gathering information from an existing process. Since DFSS involves creating a new process or product, there is no process to pull existing data; things differ.

These requirements should be translated into system, sub-system, and component-level design requirements. The QFD and the Characteristic Matrix can be used to drive the customer’s needs from the machine level down to component level requirements. The team can then use this information to create multiple design concepts. Different assessment tools, such as benchmarking or brainstorming, can be used in order to assess how well the different design concepts match customer and business needs and their likelihood of success. The team will then evaluate all the options, and choose a final design by using tools like a Pugh Matrix. If you’re hiring a consulting company to help with your deployment, use their methodology as their training materials will be tailored around it.
The Six Sigma methodology – Define, Measure, Analyze, Improve, Control, or DMAIC – is known for its ability to eliminate problems resulting from variability in manufacturing, engineering and transactional processes. There will be those times, though, when no improvement will enable an existing process to meet customer expectations. The 11 known Design for Six Sigma (DFSS) Methodologies aids businesses and organizations create new processes, products, and services in a manner that guarantees customer satisfaction. The various methodologies listed and explained above find usefulness in multiple fields, and your choice of methodology is dependent on the field and product. CDOV is another popular methodology used in products and services design that meet six sigma standards. CDOV consist of a four-phase process similar to the five phases of traditional Six Sigma improvement methodology.

The group adds controls to the process to ensure it does not regress and become ineffective once again. When teams have clarity into the work getting done, there’s no telling how much more they can accomplish in the same amount of time. Total Quality Management (TQM) - One of the original management systems, TQM teaches that every employee, management to janitor, is responsible for quality deliverables and a quality work experience.
