Most companies have a well-defined product development process that is carefully created while keeping all formal indicators in mind. It takes a significant amount of time and money for a firm to create a new product or process from the bottom up. Product sales suffer if the design does not satisfy the customer's genuine desires and expectations, or if the product does not deliver the value the consumer is prepared to pay for. The cost of redesigning goods and procedures is high, and it extends the time to market.
It may not surprise you that only a small percentage of product development failures are attributable to technical issues with the product's performance. The most common reasons for new product failure are marketing and market factors. The creation of items that the client did not desire and the development of me-too products are two of these factors.
Customers will be happy and a firm will profit financially if it can find a way to design Six Sigma quality into a product, increasing the likelihood that its new product will do well in the market. To achieve Six Sigma performance, Six Sigma tools need to be incorporated from the start of the product development cycle.
Design for Six Sigma approach is a method for product development that focuses on taking extra steps in advance to ensure that the customer's wants and expectations are understood well before starting the design stage. Every function of the DFSS necessitates the participation of all stakeholders. You may attain greater levels of quality for new goods or processes by simply implementing a DFSS methodology. Design for Six Sigma is not a replacement for a company's existing product development process; rather, it complements New Product Development by using a set of statistical techniques to objectively improve decision-making and outputs in an area that has traditionally been regarded as more art than science. DMADV and DCCDI are some examples of the same.
These methods should not be used to make incremental modifications to a process or a design. The DFSS is used to keep quality problems at bay, it is a preventive method. When you aim to optimize your design to match your customers' actual desires and expectations, reduce time to market, deliver a high degree of initial product quality, and succeed the first time, use the DFSS strategy and methodology.
The statistical tools used may be daunting to teams unfamiliar with Six Sigma management practices and DFSS might not provide instant advantages, just like Six Sigma, however, it helps a lot in the long term. The DFSS technique offers the supporting data needed to make statistically sound judgments in a shorter length of time, thereby lowering costs while improving product quality. DFSS analyses essential consumer demands then prioritizes and converts the top customer needs into project specifications.
Traditional design procedures are based on a set of assumptions about the qualities of a product that will sell. DFSS is unique in that it asks, "What will buyers buy?" and then summarizes the answers.
