Relationship between just-in-time manufacturing practices and performance: A meta-analytic investigation

Just-in-time (JIT) manufacturing is among the most commonly researched topics in the area of operations management. This study examines the relationship between JIT manufacturing practices and performance outcomes by means of meta-analysis of correlations approach. Based on an in-depth analysis of literature spanning from 1992 to 2008, the results of this meta-analytic investigation support a positive relationship between JIT manufacturing practices and aggregate performance. However, the findings suggest that not all individual JIT practices are associated with all types of performance outcomes. This study highlights the JIT practices that have the greatest impact on individual performance outcomes and emphasizes the role of moderating factors in the relationship between JIT practices and performance. Theoretical and managerial implications are discussed and directions for future theory building in JIT are presented.     

Working below and above the line: the research–practice gap in diversity management

In HRM, a line can be drawn that distinguishes research on formal organisational programmes (above‐the‐line research) from research on organisational practices as they are experienced by employees (below‐the‐line research). Diversity management research has heavily emphasised below‐the‐line research using methodologies that measure employee perceptions of diversity management activities. This research demonstrates an impact of diversity management on employee reactions and identifies unit‐level factors (e.g. leader behaviour) that impact the effectiveness of diversity management activities. However, below‐the‐line research is not able to answer HR professionals' questions about which diversity management activities should be adopted when, and so a research–practice gap is developing. I explain how both academics and practitioners would benefit from more above‐the‐line research examining the impact of formal organisational diversity management activities as reported by senior managers or documented in organisational records.     

On the Effectiveness of Incentive Pay: Exploring Complementarities and Substitution between Management Control System Elements in a Manufacturing Firm

Abstract

Extant research already emphasises that complementarities and substitution involving incentive pay and other elements of an organisation's management control system play an important role in terms of explaining the effectiveness of incentive systems. Despite this awareness calls continue for more research addressing the need to better understand how interdependencies arise among management control system elements and how they affect organisational effectiveness. Based on an in-depth case study on the implementation of a new incentive system in a manufacturing firm, we seek to provide more research and insight into how incentive pay features in complementary and substitutional relationships in an individual organisational setting. Greater insight can help illustrate how complementary and substitutional relationships unfold in even more complex ways than current research indicates, as well as how the effectiveness of the incentive system in the individual organisational setting is determined by these relationships.     

How to unlock the benefits of MRP (materiel requirements planning) II and Just-in-Time

Manufacturing companies need to use the best and most applicable parts of MRP II and JIT to run their businesses effectively. MRP II provides the methodology to plan and control the total resources of the company and focuses on the processes that add value to their customers' products. It is the cornerstone of total quality management, as it reduces the variability and costly activities in the communication and subsequent execution of the required steps from customer order to shipment. JIT focuses on simplifying the total business operation and execution of business processes. MRP II and JIT are the foundations for successful manufacturing businesses.     

Further investigating the influence of personality in employee response to organisational change: the moderating role of change‐related factors

This study investigates factors influencing employees' job satisfaction following an organisational change. Extending previous research on effects of individuals' openness to experience and conscientiousness during organisational change, we posit that aspects of change context, such as the extent to which change impacts the individual worker's job and the extent actions of management are procedurally fair, can account for varying influences of these two global personality traits on employees' job satisfaction following a change. In contrast to earlier studies focusing on change‐related effects on task performance, conscientiousness can play a positive role on job satisfaction following a change along with openness to experience. Results of this study confirm that influences of personality on individual reactions to change are complex. While the positive influences of an individual's openness to experience on job satisfaction tend to occur only when fairness associated with change implementation is high, positive influences of conscientiousness are the highest when both procedural fairness is high and the extent of impact on the individual's job is low. Implications of these findings and further research considerations are discussed.     

Business ethics: the materiel/manufacturing perspective

The discussion of purchasing practices and product integrity, which have ethical implications for materiel/manufacturing management, serves to illustrate how routine decisions can have larger implications for the firm as a whole. Management needs to take a proactive role in confronting ethical issues by (1) demonstrating a corporate commitment to sound ethics in business practices, (2) providing written policies where appropriate to provide a basis for sound ethical conducts, (3) educating various functional areas to understand their responsibility in seeming unrelated ethical problems, (4) delegating authority in ethical issues where such issues are considered in decision making, and (5) fostering interfunctional communication as a means in establishing corporatewide responsibility. The basic philosophical principles of JIT serve as a blueprint for recognizing and managing ethical responsibility. The unexpected by-products of a JIT implementation may be vendor/customer good will and an excellent reputation for the firm.     

HR,perceived organisational support and organisational identification: an analysis after organisational formation

Academic research has rarely investigated the role that people management plays in encouraging employees to identify with their employing organisation. This article reports on a study investigating the role that employee perceptions of the HR environment plays in encouraging organisational identification and the importance of perceived organisational support in this relationship. Two research surveys are discussed, one carried out shortly after the formation of the new organisation within the UK National Health Service, and one is a replication study undertaken 13 months later. The results show that key HR‐related factors predict organisational identification; this effect is both direct and indirect through perceptions of organisational support. The findings also demonstrate that, as the organisation matures, there are some interesting changes in which aspects of the HR environment predict identification and perceptions of organisational support.     

Management initiatives and just-in-time manufacturing

Numerous benefits have been claimed for firms that implement just-in-time (JIT) approaches to manufacturing. While a fair number of Western firms have been successful at such implementations, other firms that could benefit appear to be addressing only a few features rather than the overall philosophy and system. This paper considers whether each of a number of management initiatives is necessary for the implementation of just-in-time manufacturing. A case-based research methodology was used for theory testing at six plants, each which claimed to be implementing just-in-time manufacturing. Data were obtained via interviews, questionnaires, direct observation, and collection of documents. Of six management initiatives considered, four were supported as necessary conditions for both JIT flow and JIT quality, as well as for employee involvement. These four are: (1) promotion of employee responsibility, (2) provision of training, (3) promotion of teamwork, and (4) demonstration of visible commitment. The other two management initiatives were rejected as necessary conditions. These are: (1) provision of workforce security, and (2) use of group performance measures. The results also indicated that employee involvement plays a central role in JIT implementation.

Absence management and presenteeism: the pressures on employees to attend work and the impact of attendance on performance

Absenteeism is an issue that has grown in importance over the past few years; however, little has been done to explore the impact of presenteeism on individual and organisational performance and well-being. This article is based on interviews collected in nine case study organisations in the UK. Two sector organisations (one private and one public) were studied to examine absence management and a conceptual model of presenteeism, with further illustration provided using data from the other seven case studies. This enabled a pattern of presenteeism to emerge, along with the contextual and individual factors which impact on it. In addition to previous research, we found that presenteeism is a complex ‘problem’ and that it is not a single one-dimensional construct, but is continually being shaped by individual and organisational factors. In addition, we found that performance and well-being are more closely related to the organisational reaction to presenteeism and absenteeism, rather than the act itself.

Improving the Sustainable Development of Firms: The Role of Employees

Stakeholders have been found to be an important driver of organizations' sustainable development. In particular, customers, governments and non‐governmental organizations push firms towards sustainability. But to what extent is sustainability really and deeply embedded within an organization's structures and processes? And what is the role of an important, but frequently neglected, stakeholder group for successful sustainability implementation: employees? The objective of this research is to better understand the impact that organizational change for sustainability has on firm performance. Also, this study seeks to understand how the consideration of employees into the process of organizational change for sustainability moderates the organizational change and performance relationship. Using data from 92 German companies from the manufacturing and services sector, the study finds that the structural implementation of sustainability is positively related to firm performance and that employee integration moderates this relationship to some extent.

Challenged and satisfied: the role of organisational ownership and employee involvement

Abstract

This study aims to offer a more fine-grained approach to our understanding of the relationship between job stress and job satisfaction. Building on organisational theory and Job Demand-Control model, we investigated an important institutional characteristic – organisational ownership – as an additional moderator to influence the interactive effects of job demands and control upon job satisfaction. Using data collected from 1838 Chinese retail sector employees, we found that this three-way interaction was strongest for employees working in foreign-invested firms, who experienced higher employee involvement at work and perceived a high level of challenge-related stress. The relationship was weakest for employees in state-owned enterprises who reported low levels of both employee involvement and challenge-related stress. Our study constitutes an early attempt to assess the impact of institutional characteristics such as ownership on aspects of human resources management, and highlights the need for further research to recognise the importance of such characteristics as contextual factors that influence the effect of organisational practices and the work environment upon individual work-related outcomes. The paper’s concluding sections elaborate on the contributions our research makes both to theory as well as to the practicalities faced by human resource managers in contexts such as China.     

Predicting pro‐change behaviour: the role of perceived organisational justice and organisational identification

This study sets out to determine some of the key factors that foster employees’ behavioural support for change management interventions. Specifically, we examine the relationships between organisational justice, organisational identification and employees’ pro‐change behaviour by analysing questionnaire‐based survey data from 137 market research employees. Full structural equation modelling results indicate that out of the four main organisational justice types, only interpersonal justice perceptions play a significant role in predicting pro‐change behaviour after controlling for same source bias effects. In particular, the relationship between interpersonal justice and pro‐change behaviour is partially mediated by organisational identification. The results additionally indicate that age is positively associated with pro‐change behaviour and tenure with organisational identification. The study as such indicates that while perceptions of fair treatment based on respectful and courteous interactions are important in encouraging employees’ behavioural engagement in change management interventions, key in this process is the role that they play in encouraging identification with the employing organisation.     

A slow burning flame? Organisational change and industrial relations in the fire service

The process of organisational change in the public sector has led to a restructuring of the employment relationship in a context of budgetary constraints, the introduction of performance indicators and the development of new management strategies. The pace of change has been uneven and mediated by service cultures that have been resistant to innovation. Our case study of a metropolitan fire brigade explores these issues and suggests that financially driven organisational change has a major impact on industrial relations and that trade union organisation rooted in workplace culture can provide a significant challenge to restructuring.     

Communicating the psychological contract: an employer perspective

The concept of the psychological contract, with its focus on the exchange of perceived promises and commitments, is increasingly used as a framework to study the employment relationship. Yet research has predominantly focused on employee views and has largely neglected the organisational perspective and the management of the psychological contract. This article begins to redress the balance by reporting a study, based on a survey of 1,306 senior HR managers, that explores the management of the psychological contract and in particular the role of organisational communication. Three distinct and relevant aspects of organisational communication are identified, concerned with initial entry, day‐to‐day work and more future‐oriented, top‐down communication. Effective use of these forms of communication is associated with what managers judge to be a clearer and less frequently breached set of organisational promises and commitments, as well as with a fairer exchange and a more positive impact of policies and practices on employee attitudes and behaviour. The findings are discussed within the context of the wider literature on psychological contracts, organisational culture and HRM. The study confirms that the psychological contract offers managers a useful framework within which to consider and manage the employment relationship.

Integrating MRP (materiel requirements planning) II and JIT to achieve world-class status

The concepts and principles of using manufacturing resource planning (MRP II) for planning are not new. Their success has been proven in numerous manufacturing companies in America. The concepts and principles of using just-in-time (JIT) inventory for execution, while more recent, have also been available for some time, and their success in Japan well documented. However, it is the effective integration of these two powerful tools that open the way to achieving world-class manufacturing status. This article will utilize a newly developed world-class manufacturing model, which will review the aspects of planning, beginning with a business plan through the production planning process and culminating with a master schedule that drives a materiel/capacity plan. The importance and interrelationship of these functions are reviewed. The model then illustrates the important aspects of executing these plans beginning with people issues, through total quality control (TQC) and pull systems. We will then utilize this new functional model to demonstrate the relationship between these various functions and the importance of integrating them with a total comprehensive manufacturing strategy that will lead to world-class manufacturing and profits.     

Just-in-time: maximizing its success potential

The effective implementation and use of JIT manufacturing practices depends largely on the education, training, and commitment of all levels of management to a fundamental quality-first policy. Management must transfer and demonstrate that commitment to every level and extension of the manufacturing endeavor. As a company establishes and reaches toward that goal, the move to JIT manufacturing practices becomes rational and justifiable. Failing to establish and commit to a quality directive greatly diminishes the potential benefits of JIT. If all levels of manufacturing participate in the JIT planning, implementing, and maintenance procedure, the realization of positive change and improvement drives the process. Total participation makes the task of JIT implementation not only possible, but practical. Enhanced mutual respect for all concerned is a likely consequence, advancing the productive environment.
