Abstract
In the last three years, benchmarking has made its mark in the list of major process and product improvement tools. Those who are interested in process design and improvement may find this tool to be fast‐acting and effective. Presents the basic elements of benchmarking with tips on working with consultants. Finally, provides experiences from a tele‐communications equipment manufacturer.

Abstract
Presents the philosophy of TQM and operational elements which allow its application in a manufacturing environment. Describes eight such elements including management leadership, employee involvement, customer focus, fact‐based decision making, continuous improvement, benchmarking, responsibility for quality at the source, and quality function deployment. These elements are then positioned in an evolutionary model for a step‐by‐step introduction of TQM into a manufacturing environment. Finally, discusses some of the expected benefits with improvement examples from the factory where the author is employed.

Abstract
Purpose
The purpose of this paper is to determine the impact level of parameters affecting wing design at low speeds using Taguchi method.
Design/methodology/approach
Using brain storming approach airfoil shape, wing angle of attack and Reynolds number are determined as important wing design parameters. Most important parameters over these parameters are determined using Taguchi method. The lift-to-drag ratio (CL/CD ratio) is chosen as the performance criterion and L8 orthogonal index is chosen as experimental study scheme for this study.
Findings
Experimental results are examined using Taguchi method. After making experiments and also analyses, Reynolds number is found as the most important and identifier parameter for aircraft wing design.
Practical implications
Taguchi method makes the experimental design for experimental studies. This method reduces the number of experiments substantially using orthogonal indices while keeping effects of uncontrolled parameters to a minimum. Reduction in number of experiments helps save time and also cost.
Originality/value
In this study, with less number of experiments, the most important parameter for aircraft wing design is determined. Moreover, with less number of experiments, not only is time saved but the design stage is also made faster.
