DFSS - The Best Way To Design A High Quality Product

By Craig Calvin

Many businesses are already familiar with Six Sigma, and how it can help improve the quality of existing products and processes within your organization. When a business is looking to improve quality, and eliminate defects, they can use the Six Sigma DMAIC method to help improve their business. The DMAIC method stands for define, measure, analyze, improve, control. This method is great when you are looking to improve something that is already in place, but is not ideal when designing a new product or process. When you are looking to introduce a new product to your business you should use DFSS, Design for Six Sigma.

If your organization is considering adding a new product or service, the decision to use DFSS should be made at the start of the design process. DFSS can be an instrumental part of your new design, however trying to implement DFSS in the middle of your design, or at the end, is not a very efficient use of the method. The purpose of DFSS is to eliminate defects in your new product or service from the very beginning, and its use requires the expertise of individuals who have had advanced Six Sigma training. DFSS may extend your design process, and it may create more work, but in the end the product or service you are implementing will be greatly improved for it.

Design for Six Sigma is actually comprised of several different methodologies. While the goals of each methodology are the same, design the highest quality product or process possible, the steps in each methodology are a little different. This allows you to choose the best methodology for your business. Some of the different DFSS methodologies are:

-IDOV: Identify, Design, Optimize, and Validate. This process allows for optimization of the process or product through modeling, simulation, and statistics. These Six Sigma Tools are used to predict and optimize the performance and design of the product or process.

-DAMDV: Define, Measure, Analyze, Design, and Verify. The need of customers is defined based on research, and then that need is measured and bench marked based on the competition or other industries already meeting the same needs. The options are analyzed, and the design is created and its performance is verified.

Define, Customer Concept, Design, and Implement (DCCDI). The DCCDI methodology also focuses on defining customers needs, but there is an added emphasis on the implementation phase of the effort. The implementation phase is where the product or process will be created and rolled out to your customers.

If your company is looking to design a new product or process, and you are looking to optimize the quality and efficiency of this product from the very beginning, then you should strongly consider the use of DFSS. DFSS will optimize your product's quality, and there are many different DFSS strategies, which allows you to pick the strategy that best meets the needs of your business. - 32179
