The Taguchi Method (Robust Design): Manufacturing New Products Consistently

08/18/23 • 40 min

Renaud and our senior engineer Paul Adams discuss the Taguchi method, also known as Robust Design. The Taguchi method is a tool used in engineering and manufacturing to improve product and process quality and reduce defects at an early stage. It is a statistical analysis approach used early in the product development process that reduces your costs and improves product quality and reliability, so is a popular way to develop products that are less risky to manufacture.

01:07 - What is the Taguchi method? (Summary)

04:01 - Would a Taguchi method analysis point out risks and provide solutions about how to change the product design and/or manufacturing processes so the product could be made consistently well?

06:36 - Example: Plastic injection molding.

12:25 - Taguchi method is not a recent innovation, it's a well-established methodology.

18:03 - What do you need for good finished products?

21:05 - Benefits of doing early Taguchi analysis.

24:54 - The concept of value loss.

30:49 - How do teams who try to develop a new product without using the Taguchi methodology usually get on?

34:13 - When to follow a Taguchi testing approach?

36:50 - Caution: Statistical approaches are not a magic bullet.
