The DMADV methodology of six sigma
The five steps of the DMADV process are spelled out in the following acronym:
The DMADV process relies on the company's ability to understand the customers' needs and determine which are unmet. Many times this is a challenge for companies as they do not know how to determine what their customer's needs are and have no idea which needs are unmet. The DMADV Method The Steps Defined During the Measure process you learn to understand the voice of the customer. This includes customer research, benchmarking, and technical research to arrive at CTQs (Critical To Quality Characteristics). Data collection, planning, and translating customer requests into designs are essential. When you reach the Analyze step, you will look back on the CTQs from step 2 and use them as your cornerstone for new ideas and design. Each idea or concept is evaluated and the best concept or design will be chosen. During the evaluation it is important to have customer feedback and input. During this phase there will be a lot of creativity, prototyping and support from the design team. The actual Design phase includes several people and teams. Development, testing, building, budgeting and many others will be included. During this time you will be involved in reviewing simulations, process modeling, risk analysis, and process charts. Finally, you have reached the Verify stage. This last step helps all teams involved transition the product, process, or service to the customer. Six Sigma is a management philosophy that "emphasizes setting extremely high objectives, collecting data, and analyzing results to a fine degree as a way to reduce defects in products and services." The structure of Six Sigma is to get as close to perfection as possible. Therefore, companies measure how many defects are in a process and then narrow them down to achieve perfection. In order for a company to achieve Six Sigma, it cannot produce more than 3.4 defects per million opportunities, where an opportunity is defined as a chance for nonconformance. DMADV is a methodology from Six Sigma. DMADV is a data-driven quality process for designing products and processes. If followed as outlined, the DMADV method will ensure success. Understanding the customers' needs and deciding how to fix problems that occur from those needs is the key tool in becoming successful with the DMADV process.
