Abstract

Purpose

The purpose of this paper is to develop a model that determines whether how much effort of preventive maintenance action is worthwhile for the consumer over the post-sale product life cycle of a repairable complex product where the product is under warranty and subject to stochastic multimode failure process, that is, damaging failure and light failure with different probabilities.

Design/methodology/approach

The expected life cycle cost is designed for a warranted product from the consumer perspective. The product failure is quantified with failure rate function, which is the number of failures incurred over the product life cycle. The authors consider the failure rate function reduction method in their model where the scale parameter of a failure rate function is maximized by applying the optimal preventive maintenance level. The scale parameter of any failure distribution refers to the meantime to failure (MTTF). The first-order condition is applied with respect to the maintenance level in order to achieve the convexity of the nonlinear function of the expected life cycle cost function.

Findings

The authors have found analytically the close form of the preventive maintenance level, which can be used to find the optimal reduced form of the failure rate function of the product and the minimum product expected life cycle cost under the given condition of multimode stochastic failure process. The authors have suggested different maintenance policies to consumers in order to implement the proposed preventive maintenance model under different conditions. A numerical example further illustrated the analytical model by considering the Weibull distribution.

Practical implications

The consumer may use this study in the accurate modeling of the life cycle cost of a product that is under warranty and fails with a multimode failure process. Also, the suggested preventive maintenance approach of this study helps the consumer in making appropriate maintenance decisions such as to minimize the expected life cycle cost of a product.

Originality/value

This study proposes an accurate estimation of a life cycle cost for a product that is under the support of warranty and fails with multimode. Furthermore, for such a kind of product, which is under warranty and fails with multimode, this study suggests a new preventive maintenance approach that assures the minimum expected life cycle cost.

Abstract

Purpose

In today's global economy, developing supply chain agility (SCA) and lean practices (LP) as resource-based view and dynamic capabilities are essential for firms to sustain their competitive advantage (CA) and enhance their operational performance (OP). The purpose of this paper is to develop and empirically test a framework to investigate how CA is achieved through SCA and LP and how these, in turn, can enhance a firm's OP.

Design/methodology/approach

For data collection, the authors adopted the survey method using self-administered questionnaires. Two-source survey data were collected in two rounds (separated by a two-month lag time) from supply chain managers, operational managers and general managers. The purpose of collecting data in two rounds was to reduce common-method bias. Likert scale (1–5) was used in the questionnaire. Smart PLS 3 and SPSS 23 were used for the data analysis purpose.

Findings

SCA was found to directly and positively affect OP. LP also positively affected OP. In addition, CA fully mediated the relationship between SCA, LP and OP.

Practical implications

This study encourages the managers of manufacturing firms to adapt LP and their supply chains (SCs) to become agile and leverage the advantages of their implementation to improve their OP and succeed in the market.

Originality/value

This study is one of the first to investigate the effect of SCA and LP on OP. Furthermore, the first study examines CA's mediating impact on the relationship between SCA, LP and OP.

Abstract

Purpose

The aim of this case study‐based paper is to study the application of Six Sigma, a breakthrough improvement strategy in the field of cell site construction of a telecom company.

Design/methodology/approach

This research provides action research of a Six Sigma project using DMAIC methodology carried out in cell site construction function of a telecom company. The research illustrates how the various Six Sigma tools and techniques were applied in a mutually inclusive manner in one project. The infrastructure department of the company had constructed 900 cell sites last year, out of which 150 were not according to standards and were either disapproved by the operations department or underwent maintenance soon after their use. In 2010, the company spent US$ 0.5 million on rework and maintenance at these sites, thus highlighting the urgency of the problem.

Findings

The paper shows how, after the implementation of the Six Sigma project, the company made savings worth US$ 0.45 million.

Originality/value

Six Sigma as a means of waste reduction has gained popularity among researchers and practitioners. The literature on the methodology of Six Sigma and the management approach towards Six Sigma is burgeoning. While various Six Sigma tools and techniques and their application are discussed in literature independent of each other, the need has arisen to observe their systematic application as they apply in a project; every company can use this breakthrough improvement strategy to improve its processes by reducing waste and deriving the financial benefits.

Abstract

Purpose

The purpose of this research is to investigate the effect of knowledge-oriented leadership on organizational performance of higher education institutions (HEIs) and examine the neglected mediating role of knowledge management (KM) processes and innovation.

Design/methodology/approach

Following the quantitative and cross-sectional research design, data were collected through self-administered questionnaire from 312 faculty members of HEIs of Pakistan. The partial least squares structural equation modelling data analysis technique was applied to test the hypothesized relationships.

Findings

The results indicate that knowledge-oriented leadership has direct and positive effect on organizational performance. Moreover, the findings reveal that KM processes and innovation partially mediate the effect of knowledge-oriented leadership on organizational performance.

Practical implications

This study underscores the imrportant role of knowledge-oriented leadership in HEIs. Findings of this research suggest that by exhibiting knowledge-oriented behaviours, managers of HEIs can effectively manage their knowledge assets, ensure successful implementation of KM processes and augment product and process innovation leading towards superior organizational performance.

Originality/value

This is amongst one of the first studies that proposes an integrated research model and examines interrelationships amongst knowledge-oriented leadership, KM processes, innovation and organizational performance in the context of HEIs.

Abstract

Purpose

This study aims to empirically investigate the effect of financial reporting quality (FRQ) and audit quality (AQ) on the investment efficiency (IE) for the firms listed on the Pakistan Stock Exchange during the period 2007-2014.

Design/methodology

The authors use pooled ordinary least squares (OLS) regression which cluster at the firm and year level to test the hypotheses. For sensitivity check, the authors also account for reverse causality and cross-sectional dependence by using the GMM and FGLS regression methods. Furthermore, the authors built their theoretical arguments based on alignment hypothesis of the agency theory and resource-based view of the firm.

Findings

The findings suggest that higher FRQ and AQ are associated with higher IE. The results for these particular estimates are robust when tested using alternative estimation techniques. Overall, the outcomes of this study are in line with the arguments presented by the alignment hypothesis of the agency theory and resource-based view of the firm.

Practical implications

This study is fruitful for policymakers’ and investors. This study finds that the audit done by the Big 4 also reduces the information gap and, thus, reduces the moral hazard and adverse selection problems, thereby enhancing the IE.

Originality

The authors extend the debate on determinates of IE and highlight two monitoring mechanisms: FRQ and AQ. The authors further extend the literature on the economic consequences of AQ in terms of IE, as proposed by Francis (2011). For the first time, this study investigates the impact of AQ on IE in a setting where minority shareholder risk of exploitation is high relative to other markets in Asia.

Abstract

Purpose

The purpose of this study is to introduce a unified framework which integrates knowledge management processes (knowledge creation, sharing, storage and documentation and acquisition), innovation capability (product, process, marketing and organizational and organizational performance (operational, financial and product quality). Then empirically test the effect of knowledge management processes (KMP) on innovation capability (IC), the effect of IC on organizational performance (OP) and the impact of KMP on OP through the mediator (IC).

Design/methodology/approach

A questionnaire was designed and addressed to the general managers of the Jordanian companies making up the target population. Statistical techniques employed included confirmatory factor analysis and structural equation modeling (SEM) using AMOS 24 to test the hypotheses.

Findings

The results show that KMP influences IC, IC affects OP and KMP impacts OP through the mediator (IC).

Research limitations/implications

The use of longitudinal data and comparisons with this study would provide further insights that would assist in generalizing knowledge related to the relationships among KMP, IC and Os' P.

Practical implications

If organizations fully comprehend KMP and IC, they would be able to implement them successfully, creating value for their companies and improving OP.

Originality/value

The existing research on KMP and IC is primarily conceptual and descriptive in nature, and empirical research confirming the real impact of KMP when developing IC is lacking. Also. the relationship between innovation capabilities and OP has not been adequately studied. Hence, this study introduces a conceptual framework which integrates KMP, IC and OP and simultaneously empirically tests the relationships among them.

Abstract

Purpose

Transformational and transactional leadership have become a fascinating issue for research since the work of Burns (1978) and Bass (1990). The purpose of this paper is to evaluate the usefulness of the concept of transformational leadership using examples of political leadership from South Asia. It is argued that the construct of transformational leadership is practically non-existent. And, if the concept of transformational leadership exists, it cannot be specifically applied to the leaders who gain popularity and achieve their goals. It is also argued that positive and negative connotation with transformational and transactional leadership, respectively, is false. The popular leadership may be good for “one-point agenda,” but not necessarily transform the system.

Design/methodology/approach

Qualitative methods, historical analysis, and discourse analysis have been employed to understand the leaders’ actions and behaviors.

Findings

The discussion around the empirical examples show that the popular-successful leadership does not necessarily a transformational leadership even though the leadership achieves the goals.

Originality/value

The popular or so-called transformational leadership may be good to achieve one-point agenda, but it may not bring the required change and fruitful results to all stakeholders if it is not backed by a transactional strategy. Future research may turn the attention in three directions: whether or not the achieved goals were transformational or transactional; evaluation of leaders’ behavior from the perspective of consequential leadership; and the role of transactional leaders in the growth and strengthening of micro and macro organizations.

Abstract

Purpose

The study explores the impact of knowledge-oriented leadership (KOL) on knowledge management (KM) processes and the indirect relationship of KM processes with organizational performance (OP) via mediating the role of creative organizational learning (COL) in cross-cultural settings.

Design/methodology/approach

This research used a survey structure of 784 faculty and admin personnel from higher education institutions in China and Pakistan. Smart-PLS, 3.2.9 was used to perform analysis.

Findings

The result shows a significant positive influence of KOL on KM processes and KM processes on OP via the partial mediating effect of COL in China, Pakistan and the overall sample. The multi-group analysis confirmed the substantial differential effect of KOL on KM processes.

Practical implications

Outcomes of this research affirm KM's university practice and recommend how higher education academics and administrators prioritize KOL, KM processes and COL while strengthening OP in a culturally different environment.

Originality/value

The current research is among the initial experiments to determine KOL, KM processes, COL and organizational (University) performance relationships in a culturally different environment. The study is among the initials that just not empirically explore the associations between the factors but sheds light on existing literature by immediately exploring COL's mediating position in China and Pakistan's HEIs.

Abstract

Purpose

This study presents a framework for integrating distinct perspectives on social entrepreneurship by combining institutional theory with the social entrepreneurship intention model. The framework assesses the relationships between social support and the perceived feasibility and desirability of social entrepreneurship, the relationships between social support and the institutional environments of social workers, and the moderating role of prior experience of social work and volunteering.

Design/methodology/approach

The model was tested using 266 validated responses from an online and paper-based survey distributed among social workers. Partial least squares structural equation modelling was used to analyse the data, and multi-group analysis was conducted to examine the moderation effects.

Findings

The findings indicate that experience moderates the relationships between the regulatory and cognitive environments, cognitive environments and social support, and social support and perceived feasibility. Experience negatively moderates the relationship between the normative environment and social support.

Practical implications

Active government involvement in the form of incentives and financial support would encourage the creation of social ventures.

Social implications

Educational programmes are also necessary to help raise awareness and increase the familiarity and knowledge of potential social entrepreneurs.

Originality/value

The study analyses the effects of institutional environmental components, recognised as highly influential on the development of social entrepreneurship, as well as the impact of perceived social support on the antecedents of the perceived desirability and feasibility of social entrepreneurship. It also addresses how social work experience modifies these relationships. Contrary to previous studies, the findings suggest that increasing social work experience isolates entrepreneurs from their environment.
