Purpose – The aim of this paper is to present the results from an empirical investigation of Six Sigma in the Indian software industry

Design/methodology/approach – The paper begins with a review of literature of Six Sigma and its role in the software industry. The importance of Six Sigma in the software domain is presented, followed by presentation of the results from an empirical investigation of Six Sigma in the Indian software industry

Findings – The research reflects the status of Six Sigma application and implementation in the software industry, identifies the commonly used statistical and non statistical and software engineering tools and frameworks used within software business; and determines the critical success factors (CSFs) for a successful Six Sigma initiative in the software/IT industry. The most important factor was management commitment and involvement. Documentation management and suppliers' involvement were found to be the least important factors.

Research limitations/implications – This study was carried out with some boundaries like the number of companies, available resources, time constraints, etc.

Practical implications – This paper dispels the myths concerning the unsuitability of Six Sigma in the software arena. At the same time it highlights the status of Six Sigma implementation in Indian software organizations and the critical success factors for implementation of Six Sigma.

Originality/value – Little research has been carried out in terms of empirical survey relating to the application of Six Sigma in the software industry like that demonstrated in this paper. The paper will be valuable for quality professionals and management personnel in software organizations.
