Design for six sigma DFSS training is applicable to the design of any industry, any product or process. It can be used to create new products and services, optimize software design and system integration, or improve the performance of existing products. Companies can use Six Sigma-oriented design to ensure that the design, production and market of products and processes are more reliable and cost-effective, thus avoiding the situation of redesigning projects at great cost.

The concept, core and advantages of (1) and design for six sigma (DFSS).

Six Sigma is considered as an effective tool to achieve high quality and excellent operation. Design for six sigma (DFSS) is basically an information-driven six sigma management system method, which is usually used in the early product development process. By emphasizing shortening the design and research cycle, reducing the cost of new product development, achieving high-performance product development process and accurately reflecting customer needs.

Design for six sigma (DFSS) is implemented in four stages: project-based identification, design, optimization and verification. Design for six sigma (DFSS) is a forward-looking method, considering how to achieve six sigma quality in the design stage of products or services.

The core of 1 and the method of designing Six Sigma (DFSS) system are:

At the initial stage of product development, the feasibility and superiority of predictive design are proved by using perfect statistical tools and a large number of data. Predicting the performance of products or services at customers in the early stage of product development is the key to achieve higher profits, higher customer satisfaction and greater market share.

2. Advantages of design for six sigma (DFSS):

Is to do it right the first time! So as to reduce the time from conceptual design to production delivery, reduce development and manufacturing costs, minimize the risk of failure, reduce the number of design changes after the product is put into production, and determine the quality and cost level of products and services according to the actual requirements of customers.

(2) The design mode of six-horse management.

DMAIC process still has limitations in product quality optimization. As we all know, quality comes first in design. Practice shows that at least 80% of product quality is determined in the early design stage, so there is no design for Six Sigma, and the effect of improving product quality only by using DMAIC process is limited. If we really want to reach the quality level of Six Sigma, we must consider another way to implement the Six Sigma management strategy-design for six sigma (DFSS). Design for six sigma is a method to realize defect-free product and process design. Based on the idea of concurrent engineering and DFx (designfor X), it adopts a systematic problem-solving method to integrate key customer requirements into the product design process, thus ensuring the development speed and quality of products, reducing the cost of product production cycle and providing effective methods for enterprises to solve product and process design problems.

With the further development of Six Sigma research, experience shows that once the process capability reaches 4σ to 4.5σ, it is difficult to make a breakthrough in the further improvement of the process, and only by redesigning the process or product can we achieve higher capability. Therefore, a set of six sigma methodology of DFSS applied to new product design and process design came into being, which corresponds to the IDDOV process proposed by American quality management expert Surbir Chowdhury, namely, identification, definition, development, optimization and verification.

1, identifying

The main task of DFSS in the determination stage is to collect and determine the customer demand of the products to be developed, and demonstrate the feasibility of the upcoming DFSS project. One of the characteristics of DFSS is to fully consider the customer's needs at the beginning of product design, listen to the customer's voice, and use some evaluation tools to identify and prioritize the customer's needs, so as to ensure that the designed products meet the customer's needs. On this basis, the external environment, market and resources needed by enterprises to meet the development of this project are systematically considered, such as the product status of competitors in the market, the technical level of enterprises, the personnel situation and the development cost, so as to determine the feasibility of the project. This stage is very important for the whole DFSS project. As the saying goes, "Many a mickle makes a mickle", if we can't fully collect and analyze customers' needs and objectively evaluate the feasibility of the project at this stage, it will bring a fatal blow to the project. The results of this stage generally include: customer demand analysis report and project cost.

2. Define

The definition stage is the core process of DFSS implementation, and the task of this stage is to clearly explain the requirements for products. In the previous stage, we have determined who our customers are, and then we know the needs of our customers. When collecting customer requirements, we can take Carnot model as a guide and pay attention to distinguish different levels of requirements. The next step is to further refine and expand customer requirements, that is, expand VOC into design requirements, process requirements and production requirements layer by layer through QFD (Quality Function Deployment), extract key customer requirements, and accurately identify and quantify customer requirements.

3, development (development)

The goal of DFSS R&D stage is to determine feasible product concepts through creative methods and evaluate alternatives through logical and objective methods. At this stage, tools and methods such as brainstorming, creative problem solving theory (TRIZ), Platts method, failure mode and effect analysis (FMEA) can be used. First of all, TRIZ is used to solve the failed conflicts, point out the clear innovation direction and focus for the team, and produce innovative solutions. The next step is to choose the best solution. Secondly, the design should try to eliminate the potential failure of products or services, analyze the potential failure mode and functional variability through FMEA, and minimize the possibility of product and process failure in the design stage.

Step 4 optimize

This stage is the optimization of product and process design parameters, and its goal is to maximize the interests of enterprises on the basis of quality, cost and delivery time. The main method is experimental design. First of all, robust design is used to minimize the differences between products or processes, optimize design performance, and thus obtain the best concept. Then adjust the output according to the target value to determine whether all requirements are met.

5, verification (Vefify)

The task of DFSS verification stage is to confirm whether the product design meets the customer's requirements and reaches the expected quality level. The three steps of verification are: verifying the capability of the production process to ensure the delivery of defect-free products at the lowest cost, establishing, testing and fixing the prototype, and testing the capability, robustness and reliability of the design. Carry out trial production to prove that the manufactured products and processes meet the requirements previously formulated.

From 65438 to 2006, Zhang Chi Consulting focused on providing six sessions of open training and project counseling for all walks of life. Six fit horses, six fit horses and six fit horses.

Assist customers to use lean six sigma consulting methodology to improve the efficiency and effect of enterprise operation, improve the quality of products and services, reduce the cost waste in the whole operation process, and consolidate the organizational culture of continuous improvement and pursuit of perfection, so as to achieve excellent operational performance, ensure the best business profitability of the organization and bring more lucrative profits to the enterprise.

1.6 horse training is divided into: green belt, black belt, green belt and black belt.
