Six Sigma's critical success factors and toolbox

Abstract

Purpose -The purpose of this paper is to put forward and classify the critical success factors (CSF) of Six Sigma implementation, as well as the tools-techniques that it utilizes in all the phases of the Define-Measure-Analyze-Improve-Control (DMAIC) structured methodology. Design/methodology/approach -A literature review of Six Sigma's CSF has been realized and also an attempt to connect them with the enablers of European Foundation for Quality Management (EFQM). A literature review of the tools and techniques utilized follows and a categorization of them according to the phase of the DMAIC. Findings -The paper has collected a list of 32 CSF which were classified according to the five EFQM enablers, and the soft-hard differentiation. A list of 39 tools/techniques used in the different phases of DMAIC and the ISO 13053-1 suggestions has also been referred. Originality/value -The final classifications of CSF and techniques of Six Sigma methodology could be a valuable tool for Six Sigma academics and professionals to understand and implement the methodology in the appropriate way.

A Genetic Algorithm Based Feature Selection for Classification of Brain MRI Scan Images Using Random Forest Classifier

“…The DMAIC cycle is a more detailed version of the Deming PDCA (Plan, Do, Check, Act) cycle with continuous improvement. The different phases (Define, Measure, Analyze, Improve, and Control) provide a problem-solving process in which specific tools has employed to turn a practical problem into a statistical problem, generate a statistical solution, and then convert that back into a practical solution [4].…”

A REVIEW OF SIX SIGMA IMPLEMENTATION IN INDIAN SMES – TOOLS & TECHNIQUES USED AND BENEFITS DRAWN

“…Six Sig ma is an imp rovement methodology, developed by Motorola in the 1980s wh ich were fo llo wed by many big industries across the world such as GE, Honeywell and Nissan [40]. Six Sig ma was a way to exp ress its quality goal of 3.4 DPM O where defect opportunity is a process failure that is critical to the customer.…”

“…Six Sig ma is a quality imp rovement framework fo r controlling processes and getting results in terms of bottom line improvement through the use quantitative tools and techniques [40]. Six Sig ma is a systematic methodology that uses statistical and non-statistical tools and techniques to maximize an organization's return on investment (ROI) through continuous quality improvement of processes by reducing defects and non-conformance [22].…”

“…According to ISO 13053-1 standard, there is an existence of so many tools and techniques which are normally used in different phases of DMAIC approach [40]. …”

Lean e seis sigma em logística

“…Seis sigma também é considerada uma das mais populares metodologias de melhoria contínua, e embora tenha sido implementada em grandes empresas de manufatura como Motorola, GE e Honeywell, não conseguiu a mesma penetração que Lean em indústrias de serviços e tampouco em países fora dos EUA (ISMYRLIS;MOSCHIDIS, 2013, p. 108). Este método garante excelência em serviços através da aplicação efetiva de ferramentas estatísticas e não estatísticas, (ANTONY et al, 2007, p. 307) buscando reduzir variabilidade dos processos e eliminar causas raízes dos problemas, e desta forma diminuir os custos, gerar valor e maior satisfação do cliente (WIKILUND;WIKILUND, 2002, p. 235).…”
