Abstract

Purpose

This paper aims to present a model of a multi‐phase multi‐product manufacturing system considering a CONstant work‐in‐process (CONWIP) control mechanism and using continuous‐time Markov chain modelling approach.

Design/methodology/approach

The model includes defining a state space then constructing the rate matrix, which contains the transition rates, followed by formulating the transition matrix. The time‐dependent probabilities that a product is in a particular state at a certain time are characterized. Performance measures related to the statistics on the waiting time and average number of work‐in‐process in the production system have been determined. Consequently, a numerical example is presented to illustrate the computations of different model aspects.

Findings

The analyses explain a foundation needed for analyzing the steady state behavior of manufacturing systems. Results have shown how production data can be easily modified for what‐if analyses by the use of Excel add‐in tool.

Practical implications

The multi‐level model outlines a framework that provides a practical tool for production engineers seeking to enhance the performance of their production system by selecting the best order release mechanism.

Originality/value

A novel aspect of the work reported in this paper is the application of Chapman‐Kolmogrov mathematics and CONWIP ordering theory, which is developed for evaluating and managing CONWIP controlled production systems.

Abstract

Purpose

This study aims to validate the KAIIAE model in the public sector and analyse the interrelationships between Enablers and Results in the King Abdullah II Award for Excellence (KAIIAE) model to better understand the dynamic logic behind improving excellence results.

Design/methodology/approach

The methodology used is structural equation modelling (partial least squares technique), and the data were obtained from the assessment processes for the KAIIAE for 98 Jordanian public organisations.

Findings

The findings showed that the award model has proven to be a reliable and valid framework, as the criteria and sub-criteria were highly correlated. The set of Enablers was strongly related to the set of Results, and the synergies between the critical criteria confirmed the importance of leadership, strategy, and processes for the organisation's excellence results. It was found that the new significant and direct relationships between “People” and “People Results” and between “Partnerships and Resources” and both “Society Results” and “Key Results” improved the understanding and implementation of the model. There was a significant interrelationship between model criteria, excluding the relationship between “Society Results” and “Key Results”, since the government's main objective is to serve society. A new structural model for the KAIIAE with the new relationships was suggested.

Research limitations/implications

This paper concentrated only on the public sector, although the excellence model has been implemented in the private sector. Features of the different types of organisations were not tested. Furthermore, the variations in size, covered fields, number of employees and provided services need to be investigated further.

Practical implications

Government award bodies can use these research findings to develop a new model version for public sector awards by combining a cohesive array of elements for any government organisational need or application. The study suggested adding new criteria or relationships or eliminating those that are not significant and have no impact on public sector organisations. The findings will assure the organisations' managers that the KAII excellence model criteria are highly correlated and synergised for public sector organisations. These criteria perform efficiently once they are considered and implemented in an interconnected manner rather than managing them independently, which makes up their management framework. This knowledge about the validity of the structure of the model allows public sector organisations to benefit fully from the self-assessment processes and improve the organisation's management, enhancing their faith in excellence award models.

Social implications

This study has contributed to the existing literature on the reliability and validity of business excellence models as a framework for implementing, evaluating, and improving excellence, particularly in the government sector. Several important insights have emerged from this study. The relevant analysis supports a new model structure for excellence in the public sector. Among the model structure relationships, the study identified the existence of new direct relationships between enablers and results. New significant and direct relationships are added to the model that advances the implementation and understanding of the model. Moreover, it informs theory about Excellence Award implementation in developing countries within the context of Jordan – a topic that has previously received limited attention in the international business excellence literature. Since there is limited research on the suitability of implementing the KAIIEA excellence model (that is based on nine criteria of the EFQM model) in public organisations, this work suggested introducing a new modification to the model to suit the characteristics of the public sector.

Originality/value

The considerable prominence of the government sector has drawn attention to the excellence parameters within its organisations. Hence, a lack of studies and inadequate knowledge in the governmental management system have limited testing excellence in the public sector. This paper provides support that the excellence model (KAIIAE model that is EFQM based) is an appropriate framework by identifying direct and significant model interrelationships for the public sector based on the actual and sufficient performance of its entities so as to drive the changes of the next model generation. This is the first study that attempts to comprehend and describe the validation of the KAIIAE model in the public sector.

Abstract

Purpose

The paper aims to investigate the waste in a job shop environment and proposes an assessment method aimed at helping companies to identify root causes of waste.

Design/methodology/approach

The seven wastes (overproducing; processing; inventory; transporting; producing defects; time waiting; and motion waste) and their relationships were explored. A waste matrix was developed to quantify in a percentage form the relationships among wastes and represents a probability that a certain type of waste will affect others or be affected by others. An assessment questionnaire was employed to allocate the source of waste and differentiate between the levels of waste. The waste matrix and the assessment questionnaire were incorporated in the assessment method to rank the existing waste in a job shop.

Findings

The developed model serves as guidelines for simplifying the search of waste problems and identifies opportunities for waste elimination. A case study was conducted to validate the model; and the results of the assessment and the real situation concur.

Research limitations/implications

This paper has investigated a method to allocate waste, quantify it and discuss the relationships among wastes without quantifying the potential savings. Further research should be done in order to investigate the level of reduction in effort and time as a result of implementing the method.

Practical implications

The approach provides a method by which managers can identify the sources of waste, differentiate between the levels of waste and rank their significance.

Originality/value

The simplicity of the matrix and the comprehensiveness of the questionnaire contribute to the achievement of accurate results in identifying the root causes of waste. The new model provides an insight into on where to concentrate effort by weighing the contributions of the different waste types.

Abstract

Purpose

The purpose of this paper is to, first, investigate the cultural attributes of organizations that may have an effect on knowledge‐related activities. Second, to build a case based on the literatures of knowledge management and learning which suggests that the phenomenon of cooperative learning may serve as an indicator of the existence of knowledge‐related activities such as knowledge creation and knowledge exchange. Finally, the paper seeks a better understanding of the linkages between these attributes and individual characteristics related to the development and transfer of knowledge throughout the enterprise, and ultimately, the organization's work products.

Design/methodology/approach

The approach of this study consists of two phases: first, development of a conceptual model based on the literature. Second, the hypothesized research model is presented and empirically tested by utilizing multiple regression analysis and simple regression analysis to investigate the climate of organizations, in order to understand the linkage between a set of organizational and individual characteristics and knowledge‐related activities found in cooperative learning groups and the resulting work outcomes. Data were collected from teams of information systems (IS) knowledge workers based at the information technology centers located in Jordanian universities. In total, 152 IS professionals from 15 system development teams across 12 universities participated in this study.

Findings

The survey instrument was shown to be both reliable and valid. Pertinent statistical analyses were then performed. The overall results from the empirical assessment were positive, thus reflecting the appropriateness of the proposed research model and hypotheses.

Practical implications

The findings of this study have implications for both academicians and managers who are interested in better understanding the nature of knowledge creation and knowledge exchange, as well as better understanding how one might prescriptively facilitate increased levels of knowledge creation and dissemination, organizational learning, and employee performance and satisfaction.

Originality/value

This study is probably one of the first to hypothesize a research model that integrates organizational climate, knowledge processes, cooperative learning and knowledge outcomes, then empirically investigate the relationships between these constructs.

Abstract

This chapter contributes to the general debate in entrepreneurship studies about the role of leadership effects. While there has been an abundance of research into the technology industry in terms of leadership and entrepreneurship, less is known about the sport industry. The human capital of sport entrepreneurs is unique due to contextual factors and needs to be studied in more depth. This chapter aims at contributing theoretically to sport entrepreneurship research by specifically focusing on leadership traits and value creation. This means acknowledging that much of the value in sport derives from the cocreation process that is made possible by good leaders. The role of project management in terms of design thinking for entrepreneurial value creation is stated. In addition, suggestions for moving the sport entrepreneurship field forward by taking a leadership approach is stated.

Abstract

Purpose

This study aims to analyze lean wastes for the poultry sector in Turkey and link lean tools to this study, focusing on identifying each lean waste that affects poultry production and proposing solutions for preventing these lean wastes in the sector. The proposed solutions aim to improve processes by suggesting different lean tools and their applications for the poultry sector.

Design/methodology/approach

The study consists of two different applications. First, the waste relationship matrix (WRM) was created to reveal the relationship between seven lean wastes and their importance order. Then, after determining lean tools for eliminating lean wastes, the optimum weight ranking and consistency ratio of the most suitable lean tools were calculated for these wastes and ranked with the best-worst method (BWM).

Findings

Results showed that overproduction is the most critical waste that impacts other wastes, followed by defect waste. Due to the nature of the sector, these wastes not only result in economic loss for the company but also in food waste and loss and issues related to animal welfare. Furthermore, the Kaizen approach and 5S implementation are the methods to eliminate these wastes. Detailed discussion on the link between lean tools and lean wastes is provided for the poultry sector.

Originality/value

This is the first study that theoretically and empirically identifies the potential lean waste affecting the poultry sector and provides lean tools for eliminating these wastes. Sector-specific explanations and discussions are presented in the study to show the applicability of lean approaches in the poultry sector to eliminate waste. In addition, this study is the first to integrate the WRM and BWM.

Abstract

Purpose

The purpose of this paper is to identify organizational resources that may enhance the performance outcomes of a learning culture; this study was undertaken in the United Arab Emirates (UAE), an emerging economy in the Arabian Gulf region.

Design/methodology/approach

A survey questionnaire was used to collect data on a sample of 254 firms from the Emirates of Dubai and Abu Dhabi. The target respondents included middle to senior managers working in logistics, operations, finance and general management positions.

Findings

The data revealed a positive relationship between learning organization (LO) initiatives and four measures of firm performance considered in the study: employee skills development, product/service innovation, cost-effectiveness and growth in revenues. This relationship was moderated by strategic orientation of the human resource management function and perceived organizational support. Effective HRM strategies and organizational support systems were identified as critical resources that can add substantial value to the performance outcomes of an LO culture. These findings suggest that investing in the development of an LO culture makes a good business sense.

Research limitations/implications

Use of perceptual measures was one of the major limitations of the present study.

Practical implications

The largely positive impact of LO-related programs underscores the strategic importance of the LO concept to maintain superior performance outcomes in the emerging knowledge economy of UAE.

Originality/value

The paper represents an initial effort at making a business case for the LO concept in a non-western context. It brings into focus the role of organizational support and strategically oriented human resource management initiatives in optimizing the performance impact an LO culture.

Abstract

Concurrent design and manufacturing is widely accepted as essential for obtaining an economically conceivable design solution for industrial production. Nevertheless the development of a viable computer‐aided inspection planning (CAIP) using CAD as input for effective NC‐measuring data preparation has not yet been successful. This paper introduces an approach to direct integration between CAD and CAIP by developing a feature‐based computer aided design/inspection planning (FB‐CAIP) system. The FB‐CAIP system contains a computer‐internal model of a product that contains sufficient information to guide the direct generation of NC code of the inspection activity. The developed small prototype system integrates knowledge‐based inspection planning with feature‐based CAD system for an automatic CNC measuring program generation of prismatic parts.

Abstract

Purpose

The purpose of this paper is to aggregate significant part of debates in the field of International Non-Governmental Organizations (INGOs) toward performance improvement by benchmarking of the Total Quality Management (TQM) practices, and to propose TQM-Benchmarking model as a seed for future research in the context of INGOs.

Design/methodology/approach

TQM practices for INGOs were first identified based on critical synthesis of the literature for both, existing for-profit TQM literature and the INGOs field-specific quality and accountability frameworks, initiatives, and practices (Jordan introduced as an example) followed by solicitation of the opinions of experts and colleagues through personal interviews and focus group discussions to define the proposed TQM-Benchmarking model.

Findings

TQM-Benchmarking model of six practices vital to INGOs performance are proposed by this review including leadership and management commitment, beneficiaries focus and participation, partnership management for sustainability, human resource (HR) focus, process management and learning and continuous improvement, and use of quality information.

Originality/value

While TQM practices succeed in improving performance of for-profit organizations, this review proposed TQM-Benchmarking model with field-specific practical pillars of performance improvement in the INGOs.

Abstract

Purpose

The purposes of this paper are to take a closer look at the relevance of the idea of the learning organization for organizations in different generalized organizational contexts; to open up for the existence of multiple, context-adapted models of the learning organization; and to suggest a number of such models.

Design/methodology/approach

The suggested context-adapted models are deduced from works arguing that not all aspects of the idea of the learning organization should be adopted by organizations in some certain generalized organizational contexts.

Findings

The idea of the learning organization needs to be reformulated, to some extent, to become fully relevant for public organizations, safety organizations, human service organizations and knowledge-intensive organizations.

Research limitations/implications

To achieve a more inclusive contingency model than presented in this article, there is a need for further research examining the (full) relevance of the original learning organizational model for organizations in various certain generalized organizational contexts.

Practical implications

Organizational actors could use one of the suggested context-adapted models fitting their particular organizational context as a starting point when considering adopting the learning organization.

Social implications

Several adaptations suggested originate in social concerns.

Originality/value

In contrast to most previous works on the learning organization, this paper adds to the existing literature by proposing several context-adapted models of the learning organization.
