HRM practices of JIT firms in Canada

Many firms have adopted the just-in-time (JIT) philosophy to compete successfully in the global environment. The literature suggests that die success of JIT implementation depends on sound human resource management (HRM) practices that will attract, maintain, and retain employees with the required workforce characteristics. However, only a few field studies investigate the effectiveness of such practices. This empirical study examines HRM practices of 69 JIT manufacturing firms in Ontario, Canada. Specifically, it identifies important workforce characteristics, recruitment sources and selection instruments used by JIT firms. It also evaluates die degree of change in training, compensation, employee retention, and labour relations practices in the firms since JIT implementation. The level of attainment of various expected outcomes of JIT implementation and die competitiveness of the JIT firms are investigated. Problems faced by HRM managers are also discussed.     

Just-in-time purchasing: an empirical investigation

The just-in-time (JIT) literature suggests that, for JIT to be successful, a manufacturing firm has to make changes in its purchasing operations. However, empirical examination of the JIT purchasing related issues is limited. For example, a literature search identified 49 JIT purchasing articles. Of these, only 14 are empirical studies; two dealing with statistical testing of a few JIT purchasing issues. This comprehensive empirical study is undertaken to investigate (a) changes in the purchasing attributes since JIT implementation, (b) supplier evaluation cri-teria, and (c) problems with JIT purchasing implementation. Statistically significant changes are observed in 28 out of 32 attributes identified in the literature, suggesting that the manufacturing firms are successfully implementing JIT purchasing programmes. Of the 14 supplier evaluation criteria, the empirical investigation shows nine of them being important. Erratic demand for the product and customized product are found to be problematic (but not very problematic as suggested in the JIT literature( in JIT purchasing implementation.     

Distinguishing Features of Just-in-Time Systems in the Make-to-Order/Assemble-to-Order Environment*

Few studies of just-in-time (JIT) implementation examine their significance in make-to-order manufacturing environments. This study examines the relative importance of several operating variables that are characteristic features of JIT systems within such environments in North America. The results suggest that the most salient features of JIT for make-to-order and assemble-to-order firms are the elimination of waste (in the form of time and defects), reduced setup time, reduced lotsize, and a smaller pool of suppliers. In addition, the results suggest that the use of non-domestic suppliers can possibly hinder efforts at JIT implementation of materials procurement.     

Evaluating the impact of lean practices on environmental performance: evidences from five manufacturing companies

Abstract

Previous evidence suggests that lean practices help organizations to enhance environmental performance. However, the impact of lean practices on the environment is still unclear. This study, therefore, aims to analyse the relationship between lean and environmental performance in two main stages: first, a review of the relevant literature was developed, followed by a multiple case study analysis conducted in five manufacturing companies. Onsite data were collected from the firms during a 5 years’ time span of research and developing semi-structured interviews. Findings indicate that the environmental performance of the companies analysed is generally enhanced in the long-term after the implementation of lean. Moreover, the results suggest that the environmental performance of the firms investigated is mainly improved by using JIT and TQM practices in a lean transformation context. The research findings provide further results remarking the possible negative impact of Kanban deliveries, 5S and TPM on various environmental performance indicators.     

Relationships among JIT practices: an interpretive modeling approach

Abstract

This research develops a model of relationships among components of Total-JIT, including JIT-information, JIT-manufacturing, JIT-purchasing, and JIT-selling, to establish an implementation hierarchy based on relative importance. The data collected relates to the relationships among JIT components and two performance measures, supply chain competency and organizational performance. Two groups are used in the research, one group of five operations management academics and another group of 30 practicing operations managers working in U.S. manufacturing firms. An interpretive structural modelling methodology is used to develop alternative structural models. The academics’ data show JIT-information emerging as lynchpin of relationships, directly impacting all other JIT practices and both performance measures. The practitioners’ data indicates that all JIT practices and performance measures are interactive as components and outcomes. This study is the first to apply interpretive structural modelling to investigate the interplay among total-JIT components and the performance measures of supply chain competency and organizational performance.     

Implementation of just-in-time in a small company: A case study

This paper deals with the implementation of JIT in a small company in Taiwan that produces different kinds of automobile lamps such as rear combination lamps and front turn signal lamps. JIT systems have tremendous effects on all operations of a firm, including design, accounting, finance, marketing, distribution, etc., and thus are of interest to all levels of a firm's management. Realizing the success of JIT, large-scale manufacturing companies all over the world have implemented JIT in their production systems with the objective of improving their competitiveness. Nevertheless, small and medium enterprises SMEs play a major role in the national economy. However, JIT has not received serious attention from SMEs. Realising the importance of improving the performance of SMEs, a case study is presented to motivate practitioners to implement JIT in their SMEs. In addition, future research directions in the areas of implementing JIT in SMEs are presented.     

Implementation of just-in-time methodology in a small company

This paper describes the implementation of JIT in a small manufacturing company and the benefits that resulted for the company's operations. Preliminary analysis identified various problems in the existing manufacturing operations. The pre-implementation and post-implementation conditions of the company arc detailed. The achievements of the JIT implementation included a reduction in material traversing, reduced lead limes and inventories leading to an overall reduction in the cost of manufacturing. A smooth flow of material from the raw material stage to the finished product stage was established. Three separate product lines were combined into a flexible manufacturing assembly line. With the adoption of a holistic approach to JIT implementation, it was found that even a small company can make significant strides towards world class manufacturing status. The experience gained by the company can encourage and benefit other small companies to embrace the JIT approach.     

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.     

An approach to learning from both good and poor factory performance in a Kanban-based just-in-time production system

In a JIT manufacturing environment it may be desirable to learn from an archived history of data that contains information that reflects less than optimal factory performance. The purpose of this paper is to use rule induction to predict JIT factory performance from past data that reflects both poor (saturated or starved) and good (efficient) factory performance. Inductive learning techniques have previously been applied to JIT production systems (Markham et al. , Computers and Industrial Engineering, 34 , 717-726, 1998; Markham et al. , International Journal of Manufacturing Technology Management, 11 (4), 239-246, 2000), but these techniques were only applied to data sets that reflected a well-performing factory. This paper presents an approach based on inductive learning in a JIT manufacturing environment that (1) accurately classifies and predicts factory performance based on shop factors, and (2) identifies the important relationships between the shop factors that determine factory performance. An example application is presented in which the classification and regression tree (CART) technique is used to predict saturated, starved or efficient factory performance based on dynamic shop floor data. This means that the relationship between the variables that cause poor factory performance can be discovered and measures to assure efficient performance can then be taken.

The impact of service R&D on the performance of Korean information communication technology small and medium enterprises

In recent years, research and development (R&D) in the service industry has attracted a great deal of attention from both academia and industrial firms. However, compared to the manufacturing sector, little research exists on the implications of R&D for the financial and/or non-financial performance of firms in the service industry. The purpose of this study is to examine the impact of service R&D on the performance of information communication technology (ICT) firms. We identify five categories of R&D activities and investigate their impact on the financial and non-financial performance of 100 ICT firms, with a focus on small and medium enterprises (SMEs) in South Korea. We postulate positive relationships between R&D efforts and a firm's performance. However, the findings only partially support our hypotheses; unexpected results demonstrate that the presence of R&D management negatively influences a firm's performance. We present detailed statistical results and discuss the implications of the study.     

BUSINESS STRATEGY,MANUFACTURING FLEXIBILITY,AND ORGANIZATIONAL PERFORMANCE RELATIONSHIPS: A PATH ANALYSIS APPROACH

It has been argued in the literature that business strategy and manufacturing flexibility independently affect the performance of an organization. However, no empirical examination of the interrelationship among these three constructs has been performed. In this paper, based on a field study of 269 firms in the manufacturing industry, the identified constructs have been used to test a theoretical model using path analysis techniques. Our results indicate that business strategy contributes both directly and indirectly to organizational performance. The findings provide evidence of direct effects of (i) business strategy on manufacturing flexibility and (ii) manufacturing flexibility on organizational performance.     

Adoption of just-in-time based quality assurance and purchasing practices

Feasibility of transforming purchasing and quality control operations from conventional to just-in-time (JIT) practices is discussed. The study is confined to the dock-to-stores area of an engine manufacturing plant. Components used in the study are selected from a representative sample of inventory classes, commodity groups and agreement types with vendors. A time/cost analysis is carried out for the components selected so as to evaluate the cost effectiveness of the conventional purchasing and quality control. Findings on savings in terms of inventory-related costs and inventory turnover through the implementation of JIT practices are reported. A transformation framework is then developed to determine the suitability of individual components for JIT based practices. Cases are presented to demonstrate the functioning of the framework.     

Small firms in multipartner R&D alliances: Gaining benefits by acquiescing

This study highlights how smaller firms gain advantages through exchange strategies in alliances. Based on a sample of 141 firms involved in multipartner alliances governed by cooperative exchange norms, our findings support the hypothesis that smaller firms are more likely than larger firms to comply with cooperative exchange norms. This finding is especially valid for firms in manufacturing industries and can positively influence new product development. This study is a starting point for additional research investigating how, when, and why firms can benefit from engaging in multipartner alliances, even if they are a relatively small player.     

Improving supply chain responsiveness through Advanced Manufacturing Technology: the mediating role of internal and external integration

Abstract

Responsiveness is one of the key performance factors that firms need to face up to the challenges posed by today’s markets. Many manufacturing firms are investing in advanced manufacturing technology (AMT) with a view to improving competitiveness. However, empirical evidence shows that investments in AMT alone do not lead to improvements in performance. In this study, a model that links AMT implementation and responsiveness through internal integration and external integration is proposed. A sample of 441 Spanish industrial companies was used to test the model through structural equation modelling. The findings highlight that internal integration needs to be supplemented with external integration in order to ensure that the implementation of AMT will result in improved responsiveness. Supply chain managers should focus on integration within the supply chain – firstly internal and later external – to obtain returns on investments in AMT in the form of improved flexibility and more reliable and faster deliveries.     

A FRAMEWORK AND MEASUREMENT INSTRUMENT FOR JUST-IN-TIME MANUFACTURING

While Just-in-Time (JIT) manufacturing has emerged as one of the major tools to enhance manufacturing competitiveness, no attempt has been made to develop a reliable and valid measurement instrument for empirical research in JIT. Without such an instrument, generalization beyond the immediate sample is difficult or misleading. We have proposed a JIT framework and developed a valid and reliable instrument with 16 summated scales for dimensions that capture essential aspects of JIT useful in assessing its impact in manufacturing environments. In addition, we discuss in detail the interactive nature of JIT practice. And, we propose a step-by-step approach to reliability and validity testing. Four JIT practices (equipment layout, pull system support, supplier quality level, and Kanban) are identified as major contributing factors to JIT performance.     

Supply chain management: A just-in-time perspective

Just-in-time (JIT) has been a widely recognized production philosophy alternative since the early 1980s. JIT principles and techniques have been widely adopted in many manufacturing firms. More recently, supply chain management has evolved as a discipline focusing on the design, planning and control of processes linking the initial raw materials to the ultimate consumption of the finished product. Supply chain efficiency is dependent on the efficiencies of the individual manufacturing organizations and the ability to connect along the supply chain. In this paper supply chain management from a JIT perspective is investigated, focusing on the linking mechanisms between successive companies and the collective efficiency of the supply chain.     

Responding to discontinuities in product-based service supply chains in the COVID-19 pandemic: Towards transilience

PurposeIn this study, we identify and characterise how organisations have responded, in ways ranging from restoration to radical change, to discontinuities in their product-based service (PBS) supply chains during the COVID-19 pandemic.Design/methodology/approachFollowing a theoretical approach that integrates transilience and panarchy theory as a response strategy in PBS supply chains, our qualitative study involved collecting data through 19 semi-structured interviews at six manufacturing firms during the first 6 months of the COVID-19 pandemic (i.e., March to August 2020) and triangulating the findings with the secondary data and that from an industry workshop. Following an inductive approach, we performed thematic data analysis in Nvivo software package.FindingsThe findings suggest characterising discontinuities in PBS supply chains as unmanageable external supply-side, demand-side or interactional discontinuities or other manageable deliberate or forced organisational discontinuities. Following that characterisation, we developed a conceptual framework combing both resilience and transformation into new service opportunities.Research limitations/implicationsWe gained insights into the first-response abilities and ways of coping among manufacturing firms during the COVID-19 pandemic. Though our findings capture a contemporary, eye-of-the-storm perspective on future directions, a longitudinal study on the pandemic could further validate and extend the modes of response that complement mitigation with the ability to accelerate change or innovation of internal process or external service offerings.Originality/valueCombining current literature with lessons learned from the firms' immediate responses, this paper's overview and characterisation of discontinuities following the COVID-19 outbreak in PBS supply chains demonstrate how manufacturing firms can foster transilience. As such, it integrates product-based supply chain discontinuities into the domain of service-based supply chains.     

Taxonomy of ERP integrations and performance outcomes: an exploratory study of manufacturing firms

Building and deploying network capabilities of firms are crucial for sustaining competitive advantage. Enterprise resource planning (ERP) systems are useful to enhance such network capabilities thorough effective information flows. Their intended goals are measured in terms of production costs, operational flexibility and supply chain performance outcomes. However, the impact of ERP system implementation on firm performance has been reported as somewhat inconclusive. This study contends that a missing link in the story is the scope and extent of ERP system implementation after investigating how the extent of ERP integration is associated with the performance outcomes of manufacturing firms. The study also posits that restructuring in the organisation and supply chains are positively associated with manufacturing performance. Since ERP often entails restructuring in an organisation and supply chains, it is anticipated that restructuring plays an important role in inducing positive impact of ERP implementation to the firm. Using a global sample of 641 manufacturers, this research identifies four distinct ERP systems integration patterns, epitomised by different extents and directions of integration, and finds a significant association among the broadest degree of ERP systems integration, restructuring and plant performance improvement. The empirical results also show that restructuring takes place most actively in a firm that implement ERP with widest scope and scale.
