Taguchi or classical design of experiments: a perspective from a practitioner

Abstract

Purpose

The purpose of this paper is to present some fundamental and critical differences between the two methods of experimental design (i.e. Taguchi and classical design of experiments (DOE)). It also aims to present an application of Taguchi method of experimental design for the development of an optical fiber sensor in a cost effective and timely manner.

Design/methodology/approach

The first part of the paper shows the differences between classical DOE and Taguchi methods from a practitioner's perspective. The second part of the paper illustrates a simple framework which provides guidance in the selection of a suitable DOE strategy. The last part is focused on a simple case study demonstrating the power of Taguchi methods of experimental design.

Findings

One of the key questions from many quality and production related personnel in organisations are “when to use Taguchi and Classical DOE?”. The purpose of this paper is to make an attempt to address the above question from a practitioner's perspective.

Research limitations/implications

The case study is based on Taguchi method of experimental design. It would be great to see the results of the study if classical DOE is performed to this study.

Practical implications

The paper will be an excellent resource for both research and industrial fraternities who are involved in DOE projects.

Originality/value

Case study and frame work.
