Robust design: This methodology serves as an amplifier – i.e.
it enables an engineer to generate information needed for decision making with
half or even less the experimental effort.
The 2 important tasks are to be performed in robust design are as
follows –
1. Measurement of quality during design and development:
It is needed to have leading indicator of quality by which we can evaluate the
effect of changing a particular design parameter on the product’s performance.
2. Efficient experimentation to find dependable information
about the design parameters: it is difficult to obtain dependable
information about the design parameters so that design changes during
manufacturing and customer use can be avoided. Also the information should be
obtained with the minimum time and resources.
