A conceptual model for the successful deployment of Lean Six Sigma

Purpose – The purpose of this paper is to examine the relationship between the successful deployment of Lean Six Sigma and a number of key explanatory variables that essentially comprise the competence of the organization, the competence of the deployment facilitator and the competence of the project leaders. Design/methodology/approach – The preliminary fieldwork involved interviews with two senior Master Black Belts; then, combined with the results of a literature review, the authors develop a conceptual model. A number of hypotheses are developed and the procedures involved in empirically testing these hypotheses are briefly explained. Findings – Technical and interpersonal attributes of Black Belts and Master Black Belts are identified as well as the factors for success in deploying Lean Six Sigma. These factors relate to: leadership, communication, behavior and awareness of Six Sigma; policies, culture and organizational support and strategy; education, training and competency of the Six Sigma experts; project improvement teams and project management; and performance evaluations based on quality criteria, information systems, data and measurement. Originality/value – The paper produces a predictive model for the successful deployment of a continuous improvement program such as Lean Six Sigma.
