Exploring Lean Six Sigma implementation barriers in Information Technology industry

Purpose The purpose of this paper is to present critical barriers and obstacles faced by Information Technology (IT) industry in the implementation of Lean Six Sigma (LSS) as the business improvement methodology. Design/methodology/approach A literature review of peer-reviewed journal articles, master and doctoral theses, paradigmatic books with managerial impact and survey reports was used to identify distinct barriers. An empirical survey, using 400 self-administered questionnaires, was then conducted. Data about 11 LSS barriers from 256 usable questionnaires, with a response rate of 64 per cent, were collected and analyzed by means of statistical data analysis software. Findings The challenges of “part-time involvement in Lean Six Sigma projects”, “time consuming”, “staff turnover in middle of project”, “difficulty in data collection” and “difficulty in identifying project scope” emerged as the most critical barriers in the context of IT industry. This research work advocates the development of a strategy for addressing the most critical barrier instead of focusing on all for successful implementation. Originality/value This paper will prove to be a fantastic resource for many researchers and practitioners who are engaged in research and applications of LSS in the IT industry. Moreover, the scarcity of literature specific to LSS in IT industry will be addressed to some extent.
