The practice of Six Sigma is a customer-centric process which reduces variations and optimizes development. It is a continuous process of improvement, with the clear intent of improving customer needs and quality. Within that practice, the process of DMADV and DMAIC are critical tools for success. Understanding the difference between the two acronyms is crucial to ensure the proper process is applied.
We are going to take a look at DMADV as it applies to the practice of Six Sigma.
DMADV is an acronym that describes a 5-step process tool used in Six Sigma. It is applied when a client or customer requires product improvement, adjustment or more commonly, when an entirely new product or service is required. The process is aimed at creating a high quality product, while keeping customer demands at the forefront of thought. It is crucial to understand that the DMADV process is used strictly for a product or process that is not in existence with the organization, but the need for it has been identified. The five steps of the process are as follows:
Define Phase
Project leaders identify wants and needs believed to be most important to customers. Wants and needs are identified through historical data, customer feedback and other sources of information.
Measure Phase
The second part of the process is to use the defined metric to collect data and record specifications in a way that can be utilized to help drive the rest of the process.
Analyze Phase
The result of the manufacturing process that is tested by teams to create a baseline for improvement.
Design Phase
The results of internal tests are compared with customer wants and needs. Any required adjustments are made at this time.
Verify Phase
The last stage of the process is ongoing. While the product or service is being introduced and customer reviews are coming in, adjustments in process may be made.
The application of DMADV methodologies are rolled out over the course of months or years, depending on a variety of factors. The end result is a product or service that is completely aligned with customer expectations, wants and needs.
