Robust Design


Robust Design is about creating products with predictable performance in streamlined product development processes.

Robust Design presents a strategic opportunity of securing a high level of controllability in product development, raising quality levels and optimising in regards to material usage and production costs.

Robust Design is based on fully objective and quantifiable criteria.

Robust Design was originally developed by Dr. Genichi Taguchi, a Japanese quality guru, who defined Robust Design as "reducing variation in a product without eliminating the causes of the variation". In other words, making the product insensitive to variation.

Internal variation

A Robust Design is insensitive to abrasion such as the wear of a machine and aging of materials.

External variation

A Robust Design is insensitive to environmental conditions such as temperature fluctuations, humidity changes and dust.

Unit-to-unit variation

A Robust Design is insensitive to variations between components caused by divergence in materials, processes and equipment.
