Abstract
Purpose
The purpose of this study is to propose a conceptual framework for the exploration of appropriate lean techniques applicable to medium and large construction companies and measure their impact on the competitiveness and economic performance of construction companies in United Arab Emirates.
Design/methodology/approach
A questionnaire survey is conducted on 215 construction professionals in UAE to investigate the lean technique’s effect on the construction companies’ performance. The data collected were analyzed with SPSS 20.0 version software using the Cronbach’s a reliability test, correlation coefficient test and Kaiser–Meyer–Olkin test.
Findings
Analysis of lean techniques in the construction industry reveals 21 lean techniques. These techniques were categorized into the six types of lean core values. Process focus was found to be the most applied type of construction core value in the surveyed companies. This is required to focus on applying other core values as it will impact the company’s economic performance positively.
Research limitations/implications
The integrity of the research findings is based on the accuracy and reliability of collected data from 215 respondents working for construction companies in UAE, implementing lean construction techniques within a their daily activates and not achieving significant project achievements in terms of quality improvement, speed and cost reduction without adopting the overall lean construction framework.
Practical implications
This research recommends a systematic approach for the implementation of the anticipated framework within a cyclical look-ahead period and emphasizes the practical implications of the proposed approach in the construction companies.
Originality/value
Research significance emphasizes increasing the effectiveness of the construction industry and influences the development of lean construction framework, which improves lean construction practices using the lean techniques. This contributes to the effort of applying lean techniques in the construction industry. Limited studies have been done in the construction industry, mainly in UAE, compared to lean manufacturing.

Abstract
Purpose
The purpose of this paper is to present a framework for integrating construction supply chain in order to resolve the data heterogeneity and data sharing problems in the construction industry.
Design/methodology/approach
Standardized web service technology is used in the proposed framework for data specification, transfer, and integration. Open standard SAWSDL is used to annotate web service descriptions with pointers to concepts defined in ontologies. NoSQL database Cassandra is used for distributed data storage among construction supply chain stakeholders.
Findings
Ontology can be used to support heterogeneous data transfer and integration through web services. Distributed data storage facilitates data sharing and enhances data control.
Practical implications
This paper presents examples of two ontologies for expressing construction supply chain information – ontology for material and ontology for purchase order. An example scenario is presented to demonstrate the proposed web service framework for material procurement process involving three parties, namely, project manager, contractor, and material supplier.
Originality/value
The use of web services is not new to construction supply chains (CSCs). However, it still faces problems in channelizing information along CSCs due to data heterogeneity. Trust issue is also a barrier to information sharing for integrating supply chains in a centralized collaboration system. In this paper, the authors present a web service framework, which facilitates storage and sharing of information on a distributed manner mediated through ontology-based web services. Security is enhanced with access control. A data model for the distributed databases is also presented for data storage and retrieval.

Abstract
Purpose
The purpose of this paper is to present a comprehensive literature review that seeks to address modern factors worldwide that are associated with the selection of current procurement methods. The aim is to develop an up-to-date multi-attribute procurement decision-making chart for selecting the appropriate method for the project.
Design/methodology/approach
Stage 1 (literature review). The search engines, Emerald; Business Source Premier; Science Direct and Sage were selected to identify journals that have published the most procurement methods-related articles. The search covered the period 1980-2015. Stage 2 (Survey) – after analyzing and appraising the literature, an up-to-date utility decision-making chart for selecting the appropriate procurement method for the project was developed. The chart was based on findings from a survey that included 57 construction professionals and who have demonstrated sound experience about the various procurement options.
Findings
There is no one best procurement method for all projects. The selection depends on the nature of the issues or problem at hand. Decision making is not a punctual act. It is often a complex process. Effective decision making also demands quality and timely information, and a careful consideration of alternatives. The multi-attribute decision-making chart presented in this paper has included modern criteria and the client would have end up with different recommendations and consequences should these criteria were not included in priority weightings.
Practical implications
The literature review provides states-of-the art research in the field of procurement methods in construction and the multi-attribute chart is intended to offer decision makers an opportunity to broaden their horizon on the different alternatives procurement routs that could lead to different consequences.
Originality/value
To the best of the authors’ knowledge, very few publications have discussed modern selection criteria for procurement methods in construction under one study. Therefore, this paper has established a platform for scholars and researchers to obtain more useful insights into procurement methods concerns. It has identified research trends in procurement methods which may allow industrial practitioners to appreciate the key concerns in their development of modern concepts and principles such as supply chain, lean construction, sustainability, innovation, value engineering, e-procurement and Building information modeling. The inclusion of these modern criteria will present and add value to procurement decision makers within the construction industry.

Abstract
Purpose
This paper employs the positivism paradigm, quantitative approach and explanatory research design. It analyses primary data obtained from manufacturing firms via structured questionnaires and uses the partial least square-structural equation modelling technique to establish the effect of individual procurement process risk on procurement performance.
Design/methodology/approach
Procurement risks are inevitable in manufacturing procurement process; a situation that could undermine the performance of manufacturing firms if not properly managed. Yet, with procurement accounting of about 14–19% of developing countries gross domestic product, the effects of procurement process risk on performance remain scarce in manufacturing firms in developing countries. Therefore, the paper aims to investigate the effect of procurement process risk on procurement performance of manufacturing firms.
Findings
In this paper, five out of the six procurement process risks studied were found to be undermining procurement performance of manufacturing firms significantly. However, the risk threshold effect on the performance differs.
Research limitations/implications
Although this research is geographically/sector bias, several insightful managerial implications can be drawn to manage procurement process risk in manufacturing settings irrespective of the area of operation. The results of this research imply that manufacturing firms' procurement process is risk prone and the effect of risk surrounding each procurement process on procurement performance differs. Hence, the need to identify and analyse the risks surrounding each procurement process before making managerial decision to spend firms limited resources in response to the individual risk to improve procurement performance in the manufacturing sector.
Originality/value
This paper is the first to provide existing and future procuring practitioners/firms with in-depth empirical evidence of the effect of the procurement process risks on procurement performance in manufacturing firms operating in developing economies.

Abstract
Purpose
The purpose of this study is to elicit the success factors from empirical evidence, as construction industry requires an improved understanding of factors for managing projects to positive outcomes. Increased stakeholder involvement, including the new technologies, achieving sustainability and safeguarding health and safety, whilst at the same time facing uncertainties, it is crucial to examine whether there are new factors that drive construction projects to succeed, especially from a value-driven perspective.
Design/methodology/approach
Using a systematic review approach, this research reviewed 172 studies published after 2004. When compared to a comprehensive project success factor framework presented by Chan et al. in 2004, 19 factors are considered new since 2004.
Findings
Though several scholarly outputs highlighted significant improvements to project operations and innovations in equipment and techniques, there has not been a comprehensive oversight since Chan’s et al. (2004) conceptual framework. This paper investigates 16 years of industry changes and identified two new success factors categories (innovation and sustainability) and 19 new factors that add to Chan’s et al. (2004) study. Consequently, a new framework of factors affecting project success was developed.
Originality/value
This paper was very specific in its attempt to find the new and additional success factors for managing construction projects. A new conceptual framework, which includes the newly identified factors, was then developed that will create a greater awareness of stakeholders’ concerns and ultimately contribute to significant improvement in developing project objectives and defining success measures.

Abstract
Purpose
The purpose of this research is to examine the impact of work–life balance on project performance with mediating role of job burnout and moderating role of organizational support and what are the indirect effects of work–life balance on project performance via organizational support. For quantifying this effect, regression analysis has been used, and to calculate variable mediation, moderation and conditional process analysis, Model of Preacher and Hayes has been utilized.
Design/methodology/approach
Four variables and 23 measurement items have been extracted from published literature. Further, data collection for this research study has been conducted through the “Questionnaire” technique. The questionnaire has been developed based on previously established questions available in the literature. Finally, to obtain a more objective assessment, a statistical model is developed, and regression analysis is performed to highlight the most significant variables that impact the project performance.
Findings
The results of the study show that work–life balance harmed project performance, and organizational support was putting the main impact on project performance. Moreover, the findings of the study include the positive association of job burnout with project performance. And a total mediation effect was observed between work–life balance and project performance, through the bootstrapping results.
Practical implications
The authors have found that the theoretical model got practical implications, both for the managers and the organization involved in the project. The first implication is that adopting suitable work–life balance practices will be beneficial and support professionals working on projects. Professionals engaged in projects, both at managerial and team levels, are exposed to work–life balance resulting from work performance and personal life responsibilities. The empirical results revealed conflicts came across due to poor time management, and these conflicts have adverse effects on personal and professional commitments. It should be one of the basic considerations for project-based organizations, to make available ample time for the professionals to be with their families.
Originality/value
This study has enabled the authors to understand the work–life balance, organizational support and job burnout and how these variables affect project performance via their relationship as described in a theoretical framework. Furthermore, this research contributes toward the field by considering different ways to balance the work–family conflicts by examining the effects of work–life balance on Job Burnout and Project Performance. This study brought some significant insights and one of its kind in the developing countries and adds to the existing body of knowledge by developing a regression model that will help decision makers and top management to further enhance their project performance.

Abstract
Purpose
The purpose is two-fold: (1) to explore the interactions of robotic systems and lean construction in the context of offsite construction (OC) that were addressed in the literature published between 2008 and 2019 and (2) to identify the gaps in such interactions while discussing how addressing those gaps can benefit not only OC but the architecture, engineering and construction (AEC) industry as a whole.
Design/methodology/approach
First, a systematic literature review (SLR) identified journal papers addressing the interactions of automation and lean in OC. Then, the researchers focused the analysis on the under-researched subtopic of robotic systems. The focused analysis includes discussing the interactions identified in the SLR through a matrix of interactions and utilizing literature beyond the previously identified articles for future research directions on robotic systems and lean construction in OC.
Findings
The study found 35 journal papers that addressed automation and lean in the context of OC. Most of the identified literature focused on interactions of BIM and lean construction, while only nine focused on the interactions of robotic systems and lean construction. Identified literature related to robotic systems mainly addressed robots and automated equipment. Additional interactions were identified in the realm of wearable devices, unmanned aerial vehicles/automated guided vehicles and digital fabrication/computer numerical control (CNC) machines.
Originality/value
This is one of the first studies dedicated to exploring the interactions of robotic systems and lean construction in OC. Also, it proposes a categorization for construction automation and a matrix of interactions between construction automation and lean construction.

Abstract
Purpose
This study aims to examine the effect of knowledge hiding (KH) on organizational citizenship behavior toward individuals (OCBI) through the mediation of self-conscious emotions (SCE), namely, shame and guilt. This paper further considers the supervisor’s Islamic work ethics (IWE) as a conditional variable.
Design/methodology/approach
In this quantity-based research, this paper collected data from 473 employees working in various service and manufacturing organizations through Google form at two-lags.
Findings
The study applied structural equation modeling and identified that employees experience SCE due to KH. More specifically, rationalized hiding was found to have a negative effect, whereas playing dumb and evasive hiding was found to have a positive effect on shame and guilt. The results also revealed SCE (shame and guilt) as mediators between KH and OCBI. Further, the supervisor’s IWE was found to be a conditional variable to strengthen the association between KH and SCE.
Research limitations/implications
The study collected data from a single source. However, the issue of common method variance was tackled through time-lags.
Practical implications
The study suggests that supervisors must communicate with employees about the negative outcomes of KH. They must create such an environment that discourages the engagement of employees in KH and encourages the employees to engage themselves in helping behaviors to maintain a productive and creative work environment.
Originality/value
This study adds to the limited literature on the emotional consequences of KH from knowledge hiders’ perspective and unfolds the behavior-emotion-behavior sequence through the emotional pathway. More specifically, this study examined the negative emotional effect of hiding the knowledge that leads to compensatory strategy (organizational citizenship behavior) through SCE (shame and guilt). Finally, zooming into SCE, this study elucidates the supervisor’s IWE as a conditional variable.

Abstract
Purpose
The market's intense competition, the unpredictability of customer demands and technological advancements are compelling organizations to adopt new approaches, such as agile new product development (ANPD), which enables the introduction of new products to the market in a short span. The existing ANPD literature review articles are lacking in portraying recent developments, potential fields of adoption and the significance of ANPD in organizational development. The primary goal of this article is to investigate emerging aspects, current trends and conduct a meta-analysis using a systematic review of 177 ANPD articles published in peer-reviewed journals between 1998 and 2020.
Design/methodology/approach
The articles were categorized based on their year of publication, publishers, journals, authors, countries, universities, most cited articles, etc. The authors attempted to identify top journals, authors, most cited articles, enablers, barriers, performance metrics, etc. in the ANPD domain through the presented study.
Findings
The major themes of research articles, gaps and future trends are identified to assist academicians and ANPD practitioners. This study will benefit ANPD professionals by providing them with information on available literature and current ANPD trends.
Originality/value
Through meta-analysis, this study is one of the unique attempt to categorize ANPD articles to identify research gaps and highlight future research trends. A distinguishing feature of the presented study is the identification of active journals, publishers and authors, as well as enablers, barriers and performance metrics.
