An Empirical Model for Managing Quality in the Electronics Industry

Much of the empirical research in the past two decades has suggested that quality management (QM) is context dependent. This research develops an empirical QM model in a technology‐based sector—electronics manufacturing. Based on quantitative and qualitative investigations of 225 electronics firms in Hong Kong and the Pearl River Delta (PRD) region of China, a path analytic model is developed. The empirical model shows that a typical quality management system (QMS) in the electronics industry is composed of four major modules, namely leadership, cultural elements, operational support systems, and process management. These modules create a series of chain effects on organizational performance, rather than acting as parallel elements with an equal impact. By quantifying their effects on organizational performance and comparing the model to others in the literature, we identify those QM constructs that are context dependent. In electronics manufacturing, process management and customer focus are more important than other elements (e.g., cultural factors) for garnering business results. This study contributes to contingency theory and research by identifying the key constructs and their relationships in a competitive, volatile, and technology‐based industry with complex supply networks.     

Evaluating the Deming Management Model of Total Quality in Services*

This article uses the Deming management model developed by Anderson et al. (1994b) as an initial template to analyze total quality in services. While the literatures addressing quality management have developed separately for products and services, the founders of total quality portrayed this management philosophy as universally oriented. Our study first replicates two earlier studies that tested the Deming management model in manufacturing industries. Using hospitals as our unit of analysis, we realized findings similar to the earlier manufacturing studies. Next, we used contributions from the MBNQA literature to test an enhanced model. Our subsequent findings support the MBNQA concept that “leadership drives the system that creates results” and provides evidence of the ubiquitous importance of leadership for ensuring the success of a quality improvement program. Finally, an anomaly of this study and those published earlier is the inability to find support for the relationship between continuous improvement and customer satisfaction. Integrating the substantial work in the service quality literature focused on customer satisfaction measurement is recommended to future researchers to help resolve this issue and further enhance the model.     

Six Sigma implementation: a qualitative case study using grounded theory

Many organisations have implemented Six Sigma, but successful Six Sigma implementation has not been fully investigated. The purpose of this study is to explore the process of implementing Six Sigma in a manufacturing plant using qualitative case study methodology. Data were collected through in-depth interviews and analysed using grounded theory to identify the main factors that emerged from the interview data and the relationships between them. Consistent with previous studies, the findings emphasise the role of executive commitment, Six Sigma Champions, and training in successful implementation of Six Sigma projects. Furthermore, the study underlines the role of effective project selection and the coexistence of other management initiatives (e.g. lean manufacturing and continuous improvement) on successful implementations of Six Sigma projects. Our findings also suggest that Six Sigma implementation leads to higher levels of customer focus. The study contributes to the existing body of knowledge in effective implementation of Six Sigma. The results include a coding paradigm for the implementation process and implications for managers and practitioners.     

Do makerspaces represent scalable production models of community-based redistributed manufacturing?

Abstract

This research explores the development of local community-based ‘makerspaces’ as potential scalable forms of redistributed manufacturing (RDM). Makerspaces are rapidly emerging in post-industrial economies and have been identified as a catalyst of local regeneration in urban areas. However, their role in local production systems is limited. There is a gap in the literature, with respect to the evolution of makerspaces and their productive contribution. The purpose of this paper therefore is to identify, classify and examine the different types of makerspaces. Our focus is on the implementation characteristics that enable industrial production activity to take place. First, we used Leximancer (to identify from the literature) three types of makerspace. Second, we then identify five RDM implementation characteristics. The characteristics were integrated together to form the RDM-makerspace implementation model. Third, case studies were purposively selected to test and advance this model. They were subsequently classified as a Type 1 (educational), Type 2 (design) or Type 3 (production) makerspace. Only one of the case studies was classified as a fully evolved Type 3 production space. The findings concur with the literature that makerspaces tend to be primarily Type 1 or Type 2. Finally, the contribution to local production theory is emphasized.     

Bringing Japanese Continuous Improvement Approaches to U.S. Manufacturing: The Roles of Process Orientation and Communications*

Continuous improvement (CI) has played a key role in Japan's quality management. U.S. companies have begun to adopt CI in recent years. This paper studies the implementation of CI in seven U.S. manufacturing companies. We view values as the core concept of culture that impacts CI effectiveness. Using both qualitative and quantitative data with a sample of seven companies, we observe empirically a relationship between process-oriented values and CI effectiveness. We also find that communications involving workers is strongly associated with CI effectiveness. Finally, we find an association between process orientation and communication frequency, and argue that communications act as an intervening variable between process orientation and effectiveness.     

An integrative framework for FMS diffusion

Existing FMS diffusion models do not capture many of the factors that impact FMS diffusion. The objective of this paper is to identify factors impacting the diffusion rate of flexible manufacturing systems (FMS), to identify measurements of these factors, to provide an integrated framework to capture and group such factors, and to propose their expected impact on diffusion. We identify additional factors that, we believe, impact FMS diffusion and we extend the existing FMS diffusion models by incorporating these factors and showing their expected impact on FMS diffusion. We identified such factors from various studies: FMS related as well as non-FMS related studies. FMS studies that focused on its diffusion, explicitly identified factors impacting such diffusion; while FMS studies that focused on other FMS aspects identified factors that we believe are relevant to diffusion and hence included them in our framework. Additional diffusion factors are identified from other non-FMS studies relating to organizational culture, organizational strategy, organizational structure, and management style. Finally, we present all the factors (explicitly mentioned by these studies or implicitly derived from them) within an integrated FMS diffusion framework and propose how these factors impact diffusion.

Quality circles—Are they working in British factories?

A survey of Quality Circle programmes in British manufacturing companies reveals that Circles introduced and used properly with full management and trade union support can and do work and have many benefits. The findings suggest that current management attitudes and actions are more detrimental to the establishment and success of a circle programme than that of the trade unions. Based on the findings, indications are made of the factors which will assist companies who are considering the introduction of a Quality Circle programme and also help those companies currently using Circles to make and keep them effective.     

Supply chain reconfiguration opportunities arising from additive manufacturing technologies in the digital era

Abstract

The aim of this study is to explore the impact of additive manufacturing (AM) technologies on the configuration opportunities of supply chains (SCs) within the digital manufacturing era. To this effect, we first conduct a critical taxonomy of existing research efforts and then propose an integrated decision-making process for the design and management of SCs defined by digital manufacturing technologies. Following, we provide an integrated framework for future SC reconfiguration opportunities arising from the adoption of AM on a supply network setting. Our analysis demonstrates the significant ramifications of AM techniques on SC configuration and sustainability performance as opposed to conventional value networks; however, existing research is evidently limited due to scope related challenges and the inherent complexity at the manufacturing echelon of the respective supply networks.     

Managing demand variability and operational effectiveness: case of lean improvement programmes and MRP planning integration

Although a lean focus is widely popular in general manufacturing environments, there are limited studies that empirically investigate how lean improvement programmes can be integrated with a material requirement planning (MRP) system. The aim of this research is to examine if the integration of lean improvement programmes with a MRP system has a positive effect on operational effectiveness when manufacturers are experiencing high levels of customer demand variability. Based on the contingency theory perspective and using data collected from the international manufacturing strategy survey (IMSS-V), a sample of 382 international manufacturing companies are first divided into two groups based on the degree of their customer demand fluctuation. Moderated hierarchical regression is then applied to each group to empirically test the research hypotheses. Statistical results suggest that operational effectiveness significantly improves when lean improvement programmes support MRP systems as manufacturers are experiencing high levels of fluctuations in demand.     

THE INVESTIGATION OF COST VARIANCES: A FUZZY SET THEORY APPROACH*

In a standard costing system, deviations (variances) of actual cost from standard cost should be investigated in order to help management identify the causes of the variances and who is responsible for them before corrective actions are taken. In reality, however, actual cost rarely equals standard cost and so many variances occur that it is impractical and uneconomical to investigate all of them. These two conflicting factors—the necessity of investigating cost variances and the impracticality of investigating all the variances—present management with the problem of deciding which variances to investigate. In this paper a model, based on fuzzy set theory, for the cost-variance investigation is proposed and applied to an actual investigation problem faced by a manufacturing company.     

From Mass Production to Mass Customization: Hindrance Factors,Structural Inertia,and Transition Hazard

Research on mass customization has largely overlooked the issue of organizational change associated with the mass production‐to‐mass customization transition. To address this gap in the literature, we conduct a longitudinal case study of a manufacturing facility belonging to a division of a Fortune 1000 discrete manufacturing firm as it seeks to transition from mass production to mass customization. We empirically identify five factors hindering the mass production‐to‐mass customization transition within the research site and articulate five corresponding generalizations explaining how and why these hindrance factors relate to the mass production‐to‐mass customization transition hazard beyond the research site (i.e., how and why the five hindrance factors, in general, threaten the likelihood of a successful mass production‐to‐mass customization transition). We then theoretically validate the five hindrance factors and corresponding generalizations by mapping them onto the antecedents and tenets of structural inertia theory. We conclude with a brief discussion of the scientific and pragmatic significance of the findings and highlight opportunities for future research.     

Dynamic issues in the planning and control of integrated manufacturing hierarchies

Integrated manufacturing operations typically are organized along hierarchical lines. Characterized by product aggregation and time horizon, hierarchical decompositions aim at easing problems associated with the complexity and scale of the manufacturing function taken as a whole. Static models have been developed and employed which facilitate the analysis and functioning of these organizations. Existing models are valuable aids in assisting goal-planning functions, but provide little guidance for directing the pursuit of goals. This paper presents a new hierarchical model of integrated manufacturing operations based on concepts of management control. The model is congruent with commonly used static planning models, while at the same lime depicting real-time, goal-achievement efforts within a dynamic operating environment. Emphasizing the interactions between goal planning and goal achievement, the dynamic model provides a means of assessing the effects of decentralization and autonomy on the goal planning and achievement process. The model is used to identify two resource-consuming chain reactions linked to replanning and goal pursuit within the hierarchy. A simple example based on the dynamic extension of a typical static decomposition illustrates the key findings.     

Can you have your cake and eat it? Investigating trade-offs in the implementation of green initiatives

Abstract

Is it possible for manufacturing or service businesses that pursue green initiatives to ‘have it both ways’? In the words of some researchers in the corporate sustainability field, the answer is ‘no’. According to those authors, executives who attempt to implement a green agenda in their firms will encounter tensions/trade-offs at various levels and in different forms. Assessment of these trade-offs is a critical issue in the formulation and implementation of corporate sustainability strategies. Similarly, some authors in the operations management field affirm that, due to the limitations of all manufacturing and service systems, trade-offs in their operations are inevitable. In order to provide insights into these important issues, our paper investigates potential trade-offs in the implementation of a green initiative in a SME that manufactures cleaning products. The results show that there is a trade-off between the green initiative pursued by the SME and its overall production costs. Interestingly, once other problems were resolved, this trade-off did not stop the SME from implementing the green initiative. Important implications for practitioners and researchers are discussed, and opportunities for future investigations are outlined.     

Prioritising indicators in improving supply chain performance using fuzzy AHP: insights from the case example of four Indian manufacturing companies

Abstract

In this contribution, we aim to prioritise the indicators to enhance the organisational supply chain’s (SC) effectiveness from an industrial perspective. It will help industries to develop strategies for managing the SC effectively and ensuring improvement in performance continuously. To achieve this, this work proposes to use a two-phase research methodology. First, 36 SC performance improvement indicators are recognised from a literature survey and from field and industrial expert’s inputs. Secondly, a structural model is proposed using the fuzzy analytical hierarchy process (AHP) to prioritise the indicators strategically to improve the SC performance. The fuzzy AHP method helps determine the priority of concerns of the identified indicators under fuzzy surroundings. Inputs in this research are taken from four ancillary Indian plastic manufacturing firms. Research findings indicate that collaborations and information exchange dimension indicators obtained the highest priority in improving SC performance. The model proposed is considered very useful for the SC managers/practitioners/decision-makers to understand better and distinguish the essential SC performance improvement indicators and to take systematic decisions specifically to improve the performance of business in a SC context. Sensitivity analysis was conducted to examine the priority ranking of the indicators.     

Measuring open source software success

Since the mid-1990s, there has been a surge of interest among academics and practitioners in open source software (OSS). While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.     

The implementation of digital technologies for operations management: a case study for manufacturing apps

Abstract

Manufacturing applications address business to business (B2B) with highly customised applications developed for specific requirements, offering highly specialised solution-oriented and service-based software components, systems, and digital tools that aim at a fast and accurate decision-making support system. The purpose of this paper is to describe the implementation of digital technologies for operations management using manufacturing or engineering apps (eApps), for product design and manufacturing processes. In particular, starting from the specific needs of two companies from mature European industries as automotive and food, this work depicts how this kind of solutions can support companies and improve their operations. In particular, related benefits and challenges faced for the full implementation of the developed tools are highlighted. Moreover a business model to exploit the manufacturing apps is also proposed. The business model proposed for the exploitation of the eApps supports the commercialisation of all the revenue streams offered by this rapidly growing sector taking into account the specific needs of the concerned stakeholders through a diversified value proposition.     

The impact of manufacturing and supply chain improvement initiatives: A survey comparing make-to-order and make-to-stock firms

Manufacturing firms aim at improving both internal and external processes to improve the competitive advantage. Such initiatives include lean practices as well as supplier rationalization and integration. In this paper, we analyze these improvement initiatives and their impact on business performance. In particular, we explore potential differences between make-to-order (MTO) and make-to-stock (MTS) firms. We use data from 216 Australian manufacturing firms. We find a clear difference of improvement focus between MTO and MTS firms. MTO firms exhibit a significant impact of supplier integration on business performance, but not for lean practices and supplier rationalization. The situation is completely reversed for MTS firms, since they have significant effects for internal lean practices and supplier rationalization, but not for logistics integration with supplier. The results show that the distinction between MTO and MTS firms is important when analyzing manufacturing and supply chain improvement initiatives.     

ENVIRONMENTAL PERFORMANCE AS A DRIVER OF SUPERIOR QUALITY

We explore theoretically and empirically how efforts to enhance environmental performance may enable other types of manufacturing improvements. Drawing on a unique data set comprised of detailed surveys of 42 automotive assembly plants, associated quality metrics, and in‐depth qualitative data from 17 automotive assembly plants, we show that attaining superior environmental performance can be a significant driver of superior quality. We highlight the synergistic and reciprocal nature of environmental and broader manufacturing improvement efforts, and show that environmental improvement tools and know‐how can be an important source of competitive advantage.
