Abstract

Purpose

This article aims to provide Design for Six Sigma (DFSS) practitioners, researchers and academicians with Ten Commandments to successfully deploy projects.

Design/methodology/approach

The commandments are the brainchild of four authors' experience and expertise for more than 15 years of DFSS deployment in the spectrum of fields as a consultant, researcher, academic and Master Black Belt in Six Sigma and general quality management and engineering disciplines. Thus ascertained commandments were validated and classified through the “Delphi Study” to ensure its applicability.

Findings

The Ten Commandments from authors' perspective include: alignment of DFSS with organisational strategy; top management support and involvement; listening to the voice of the customers (VOC); effective training programme for right project teams; project selection and prioritisation; linking DFSS with ISO international standards; linking DFSS with organisational learning and innovation; linking DFSS with the 4th Industrial Revolution; effective use of DFSS methodology and the integrated tools within the methodology and reward and recognition schemes.

Research limitations/implications

The commandments presented in this article are the authors' personal experience in different industrial scenarios and settings and demographical locations. The authors are planning to conduct a longitudinal survey to understand further insights of these commandments with the input of several DFSS Black Belts and Master Black Belts, academicians and leading researchers from various countries.

Originality/value

All the organisation's stakeholders can use this article as general guidelines to ensure effective deployment of the DFSS approach.

Abstract

This is an R&D project on design optimization of the inner shield of the Omega colour picture tube at Samsung SDI in Korea. This was an R&D project which basically used the IDOV (Identify, Design, Optimize, Validate) process for Six Sigma implementation. Most Six Sigma projects use the process of DMAIC (Define, Measure, Analyze, Improve, Control). However, this project introduces a new cycle, RDIDOV (Recognize, Define, and IDOV∥. Here CPT means Colour Picture Tube. Samsung SDI is one of the two companies which began Six Sigma in Korea. This case study shows a good exmaple how an R&D Six Sigma project can be usefully employed in manufacturing companies using a new process cycle.

Abstract

Purpose

Six Sigma has been part of our business lexicon for more than a decade. Debates on its emergence as a strategic initiative have created critics who consider it as an old wine in a new bottle. Is Six Sigma a management fad? This article presents some common myths and realities of Six Sigma business strategy. The paper provides an excellent resource for those people who would like to know whether Six Sigma is just a management fad or fact.

Design/methodology/approach

The paper discusses some common myths and realities of Six Sigma by critically reviewing the existing literature on Six Sigma and also provides a greater insight into the viewpoints of leading academics and practitioners.

Findings

Six Sigma is neither a fad nor just another quality initiative. It relies on factual data coupled with hard work and is a disciplined and structured problem‐solving methodology. The authors strongly argue its integration with other continuous/breakthrough improvement initiatives for sustaining the merits of Six Sigma in the twenty‐first century. The paper also elucidates the role of academia in further developing and establishing the best practices of Six Sigma management strategy. Six Sigma will evolve over time like many other initiatives – however, the key concepts, the principles of statistical thinking, tools and techniques of Six Sigma, will stay for many years, irrespective of whatever the “next big thing” will be.

Practical implications

In the authors' opinion, Six Sigma will continue to grow as a powerful management initiative for achieving and sustaining operational and service excellence. However, what will eventually determine whether Six Sigma is viewed by businesses as just a passing management fad or not, largely depends on the leadership and success of its execution. The authors believe that organisations developing and implementing Six Sigma should not view it as an advertising banner for promotional purposes.

Originality/value

The paper yields a great value to both researchers and practitioners of Six Sigma in dispelling the myths of Six Sigma, which have been quite prevalent in the business fraternity.

Abstract

Purpose

Enterprise social media (ESM) are widely adopted in the organizations with the aim of improving employees' work performance. The purpose of this paper is to investigate the moderating effects of work context characteristics on the relationships between proactive motivations and usage behaviors of ESM communication and task collaboration feature sets.

Design/methodology/approach

Questionnaire surveys were used to gather data from 307 randomly chosen Chinese employees, who were also ESM users. The research model was examined using linear regression methods with the SPSS 24 software package.

Findings

The results indicate that work context characteristics (i.e. task interdependence and perceived organizational support) had significant moderating effects on the relationships between proactive motivations and usage behaviors.

Originality/value

By extending the model of proactive motivation to the ESM context, this study directly addresses how users can be energized to use ESM features.

Abstract

Purpose

The chapter highlights some of the challenges of research on supplementary education, and indicates ways in which the challenges were tackled in one particular study on Chongqing Municipality, China.

Design/methodology/approach

The Chongqing research investigated the determinants of demand for shadow education by Grade 9 students, using a mixed-methods design. A questionnaire was used to collect data from students and parents on various background details and on the nature of the tutoring that they or their children had received. Interviews of a smaller number of respondents provided qualitative data that supplemented and illuminated the quantitative responses.

Findings

Different methodological decisions may have different implications. The sampling strategies in the study limited the generalizability but increased the feasibility of the fieldwork and comparability of findings. The top-down strategy of gaining access secured high response rates in the surveys, but to some extent decreased some participants’ willingness to provide information on gray areas. Interviews generated deep and detailed data, but some sensitive topics were intentionally avoided. Informal chats with note taking were constrained in depth and breadth by random time slots and venues, and some details were difficult to record. However, the approach expanded the horizons and facilitated the triangulation of information.

Originality/value

Discussion focuses on collection of data, and stresses the importance of cultural, social, and economic contexts. The chapter may be seen as a case study that provides insights into methods for researching forms of supplementary education. Methodological lessons from the fieldwork in Chongqing have wider relevance, particularly in settings where regular teachers provide extra private classes.

Abstract

Purpose

The purpose of this paper is to provide various perspectives on the future of quality professionals from a number of leading academics and practitioners around the world.

Design/methodology/approach

The approach taken was to collate opinions from a number of leading academics and practitioners from different countries. It was also important to ensure that all participants in the study had a good knowledge and expertise in the field of quality and operations management. Most of the participants had over 30 years of experience in quality and related disciplines and some of them are pioneers in their respective fields of quality management/engineering.

Findings

As the global economic forces were radically changing, it is essential that quality managers face the future with quality-based integrated management programmes that fit the new business era rather than continuing with systems that may have worked in the past.

Research limitations/implications

Due to time constraints, the number of people participated in the study was relatively small. However, the author is currently pursuing a larger study looking into the future of quality professionals within the context of Scottish Manufacturing and Service companies.

Originality/value

The paper provides an excellent resource for many researchers and practitioners equally who are engaged in research and applications on this topic. Moreover it was observed during the review of current literature that very few studies are related to the topic on the future of quality professionals and their future roles in modern organisations.

Abstract

Purpose

The purpose of this study is to bring out the machining characteristics of abrasive jet machining on carbon fibre reinforced thermoplastic composites utilized in aerospace and biomedical applications. Biocompatibility materials such as carbon fibres and polyether thermoplastics, like polyether ether ketone (PEEK) are widely used in trauma and orthopaedic surgery. Due to the heterogeneity, layered construction of reinforcing phase bonds with a resin matrix and abrasiveness of the reinforcing fibre, traditional drilling of carbon fibre-reinforced composites (CFRPs) are always challenging task.

Design/methodology/approach

An investigation is carried out using abrasive jet machine for drilling PEEK filled with 30 Wt.% carbon fibre (CF 30) using threaded and unthreaded nozzle to study the effect of abrasive jet process variables on surface roughness (Ra) and delamination factor (DF). Pressure (P) and stand-off distance (SOD) as important technological abrasive jet factors were evaluated. It is found that higher abrasive jet pressure and minimum SOD maybe selected to achieve minimum delamination.

Findings

The study further reported that the threaded nozzle minimized the surface roughness by 43% and delamination factor up to 12%.

Originality/value

This study of experimenting and observing the machining characteristics of CF30 by using a threaded nozzle is being tried for the first time and the results are deliberated.
