DFSS is basically an information-driven six sigma system method, which is usually used in the early development process of products. By emphasizing shortening the design and development cycle and reducing the cost of new product development, high-performance product development process can be realized and customer requirements can be accurately reflected.
The core of DFSS system method is to apply perfect statistical tools in the early development stage of products, thus proving the feasibility and superiority of predictive design with 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 customer satisfaction, higher profits and greater market share.
Based on the project, DFSS is implemented in four stages: identification, design, optimization and verification.
The effective implementation in design for six sigma is as follows:
1, management commitment
The implementation of design for six sigma is just like the implementation of Six Sigma Improvement, and the key lies in the approval from top to middle managers. No matter how good a plan is, it will be extremely difficult to implement without the full support of middle and senior managers. Therefore, it is necessary to ensure that the management fully realizes the significance and value of implementing design for six sigma, and believes that the design of Six Sigma project will never pose a threat to their position and position in the company. The strong support of management will make everyone in the enterprise feel the determination of senior leaders to implement Six Sigma design. If senior leaders not only support and encourage policies, but also middle leaders will follow suit, then the design for Six Sigma can be promoted from top to bottom.
2. Company leaders and project teams
Once organizations at all levels agree on the design of Six Sigma implementation method, six project leaders (advocate, senior black belt and black belt) must be selected. Advocates initiate and support black belt projects at the company level, and senior black belts are responsible for training black belts and providing guidance, consultation, management, supervision and coordination. Under the guidance of advocates and senior black belts, the black belt defines the work items in design for six sigma and leads the team to complete the projects. The project leader must be an efficient manager who can inspire himself and others. He can make others feel dependent, responsible for the project objectives, dare to authorize, pay attention to details and strictly supervise. In short, a leader must be found to lead the project. The organization should make sure that the right person has been selected for the project. At this time, an open meeting with senior, middle and project leaders should be held. Project leaders should be familiar with various factors involved in Six Sigma project design, fully understand the work of various departments, be able to exercise power and master project management skills, and be respected. Another important factor affecting the success of the project is to establish a fully authorized, multidisciplinary and cross-departmental project team. The design of Six Sigma project should be composed of marketing, R&D, technology, production, quality management and after-sales service personnel, and team members should receive green belt training and work together. In order to ensure the success of implementation, the organization should formulate and implement an incentive mechanism.
Step 3 communicate effectively
It is the responsibility of the inter-departmental project team to establish accurate and effective communication methods. Every member of the whole organization should have the same understanding of the same information, and the company should provide a glossary about design for six sigma, preferably in a language that everyone can understand. All members of the team should understand these concepts and definitions, such as what is the significance of design for Six Sigma? How to explain customers' needs through QFD? What is the TRIZ method? What is the meaning of robust design? And so on. Let each member communicate through efficient communication channels. Once receiving the information, they can make a quick response and accurately understand the content and meaning of the information. Design for six sigma needs clear, concise and timely information exchange, which is very important for the team. Misunderstanding or misinterpretation of information will greatly reduce work performance.
4. Education and training
Like Six Sigma's improved training, design for six sigma should also be integrated with the project. Training and practice are carried out in stages. After a long period of time, such as half a year or a year, the training is over and the Six Sigma project design is completed. Training is the core of six sigma education and training. If you only practice in class under the guidance of your tutor, you won't master much. Even in design for six sigma, we still have to spend a lot of time for students to communicate, attend seminars and train their display (demonstration) ability. Design for six sigma also put forward higher requirements for training lecturers. The instructor's role will become a coach. They should not only understand the design of project management, statistical technology and Six Sigma method, but also have rich engineering practice experience and the ability to lead the team to achieve the goal. Practice has proved that this learning method of integrating theory with practice is very effective.
5. Integration strategy
The practice of foreign enterprises proves that the integration of design for six sigma with other work and the implementation of ISO 9000 system will significantly improve the performance of enterprises, otherwise it may bring unnecessary contradictions and conflicts, and enterprises must attach great importance to it. Design for six sigma is a brand-new concept, which should be solidified into the daily business of enterprises and into the quality system documents. All effective practices should be recorded, which can not only consolidate design for six sigma's achievements, but also promote enterprise reform.
6. Improve profitability
The combination of project and profit will lead to the change of corporate culture. Imagine, when the business leader finds that the financial data of the new method is obviously better than before, what reason does he have not to make changes? Total quality management has also won remarkable benefits for enterprises, but enterprise leaders can't tell which are the contributions of total quality management and which are the contributions of other factors; The return on investment of TQM is difficult to calculate, and the implementation of TQM in enterprises is mainly based on the trust in this method rather than the financial benefits seen. However, Six Sigma Management emphasizes that the return on investment is a part of the process of project confirmation and project selection, and then it is tracked until the project is profitable. This way will change the decision-making psychology of leaders, who will not hesitate to invest, support and promote the design of Six Sigma projects.
