Abstract

Purpose: Lean Six Sigma (LSS) is a continuous improvement methodology that has been adopted by several companies as a strategy to increase their competitive advantage. However, due to the misuse of LSS theory in practice, a high rate of implementation failure results. There is a need for a structured and standardised framework to describe how the LSS initiative should be implemented and sustained over time. As a result, this study aims to develop a practical, user-friendly and accurate LSS road map for a Scottish manufacturing small and medium enterprise.

Design/methodology/approach: The approach was to analyse existing literature on lean and Six Sigma that included road maps and critical success factors (CSFs) in order to design an in-company, quantitative survey instrument. The aim of the survey was to evaluate employees’ perceptions on the importance of LSS CSFs for the successful implementation and sustainability of a continuous improvement initiative. Based on the literature and results from the data collected, an LSS reference guide – in the form of a road map – was designed to support LSS implementation and sustainability.

Findings: A customised LSS reference guide in a road map format for the Scottish SME was proposed. This road map was developed by adopting existing successful road maps from the literature into consideration and then adapting them to fulfil the company’s particular perspective on CI. This study complements current literature on LSS road maps and corroborates LSS CSFs as crucial for successful LSS implementation and sustainability, regardless of the type of company and/or culture. However, a degree of importance is ascribed to the organisation’s culture.

Research limitations/implications: Whilst a survey was used as the data collection instrument future interviews with employees would enhance the understanding of the organisational culture and hence further improve the road map.

Originality/value: The authors developed a practical and strategic roadmap for a Scottish packaging small- and medium-sized enterprise (SME) which can be used by other similar SMEs. The proposed LSS road map can be replicated and/or adapted for companies in their application of LSS. The methodology by which this study’s road map was designed can be used as a guide in the development of further CI road maps.

Abstract

Purpose: Lean Six Sigma (LSS) has been accepted globally across the service sector as a management strategy for achieving process excellence. In the past one decade, the application and success of LSS in services is remarkable across Information Technology (IT) organisations. However academic research has seldom derived implications from this practitioner’s science of improving processes. The purpose of this paper is to feature the application of LSS in the system maintenance department of a manufacturing firm. Design/methodology/approach: The research reported in this paper is based on a case study carried out in system maintenance department using the Six Sigma Define-Measure-Analyse-Improve-Control (DMAIC) approach and its application in reducing complaint resolution time. Findings: The LSS article presented here highlights a real-world case study of how LSS DMAIC methodology help reduce the complaint resolution time from 12.5 to 8.5 h (~30 per cent improvement) and the corresponding standard deviation from 28 to 17.4 days. This study also has resulted in reducing the turn-around-time of all the core processes in the organisation. The indirect financial savings estimated as a result of this overall impact was around INR2.5m. Research limitations/implications: The research was restricted to studying the impact of LSS in one organisation. The validity of the results can be improved by including more organisations and more case studies from the IT support services. Originality/value: This could serve as a resource for both practitioners to derive useful implications and to academicians as it contributes to the LSS body of knowledge towards theory testing.

Abstract

This paper includes the systematic literature review on lean business models used in the healthcare industry to aid in reducing waste, costs, and improving overall patient care and satisfaction. A systematic literature review was conducted to analyze lean business models used in the healthcare industry regarding lean thinking in healthcare, object technology, Six Sigma and quality models, organisational culture and lean implementation, healthcare delivery method study, clinical services redesign program, process improvement cost model, vendor managed inventory, supply chain innovation, strategic customer service orientation, and the model of care in the healthcare industry. The systematic review of the literature on lean business models suggests that the models such as several process improvement cost models, lean thinking models, managerial process improvement, and models of care can be used in the healthcare industry to reduce waste and costs and improve patient satisfaction. Sustaining competitive advantage for accountable care organisations was also found to help in accomplishing the value demands required by customers and competitors. This paper can be used as a guide for implementing lean business models and lean practices and the review can be used to help organisations see the benefits in using lean practices in the healthcare industry.

Abstract

Purpose: The purpose of this paper is to provide lean and six sigma professionals and researchers of tomorrow with Ten Commandments of Lean Six Sigma (LSS). Design/methodology/approach: The Ten Commandments of LSS are based on several years’ experience of four authors who act as researchers, LSS Master Black Belts, consultants, practitioners and trainers on various topics of Lean, Six Sigma and general quality management and continuous improvement. Findings: The Ten Commandments in our opinion include: alignment of LSS initiative with organisational strategy, LSS project selection and prioritisation, selection of top talent for the project execution, leadership for LSS, effective training and design of appropriate curriculum for different LSS roles, development of reward and recognition system, LSS sustainability, Linking LSS with Organisational Learning and Innovation, Linking LSS with Environmental Management System Standards and finally LSS and Big Data. Research limitations/implications: The key features outlined in this paper are based on the practitioners of LSS. The authors of this article are planning to pursue a global study to critically evaluate these commandments by various practitioners of LSS. Originality/value: The senior managers and executives of various businesses can use these commandments of LSS as a guide to achieve and sustain competitive advantage.
