Abstract

Purpose

The aim of this case study‐based paper is to study the application of Six Sigma, a breakthrough improvement strategy in the field of cell site construction of a telecom company.

Design/methodology/approach

This research provides action research of a Six Sigma project using DMAIC methodology carried out in cell site construction function of a telecom company. The research illustrates how the various Six Sigma tools and techniques were applied in a mutually inclusive manner in one project. The infrastructure department of the company had constructed 900 cell sites last year, out of which 150 were not according to standards and were either disapproved by the operations department or underwent maintenance soon after their use. In 2010, the company spent US$ 0.5 million on rework and maintenance at these sites, thus highlighting the urgency of the problem.

Findings

The paper shows how, after the implementation of the Six Sigma project, the company made savings worth US$ 0.45 million.

Originality/value

Six Sigma as a means of waste reduction has gained popularity among researchers and practitioners. The literature on the methodology of Six Sigma and the management approach towards Six Sigma is burgeoning. While various Six Sigma tools and techniques and their application are discussed in literature independent of each other, the need has arisen to observe their systematic application as they apply in a project; every company can use this breakthrough improvement strategy to improve its processes by reducing waste and deriving the financial benefits.
