Team integration is a concept that has been widely fostered in alliances as a way of improving collaborative relationships between diverse organisations. However, deeper insights into the practice of high levels of team integration remain elusive. The purpose of this paper is to develop a deeper understanding of team integration through the “lived experience” of practitioners in an alliance.Design/methodology/approachThis study employed a qualitative research methodology. Using a phenomenological examination, via the lived experiences of 24 alliance practitioners, the practice of alliance team integration has been investigated based on the key indicators that foster alliance team integration: team leadership, trust and respect, single team focus on project objectives and key results areas, collective understanding, commitment from project alliance board, single and co-located alliance team, and free flow communication.FindingsThe findings highlight that alliancing gives the project teams’ flexibility to change and adapt, to advance the collaborative environment and that successful integration of multi-disciplinary project teams requires commitment to the identified indicators. These findings have led to the development of a framework of leadership for successful alliance integrated practices. It is proposed that to influence the leadership for the purpose of achieving successful integration practice, a team-centric approach is required which includes four elements: task and relationship-oriented behaviours; collaborative learning environments; cultivating cross-boundary networks; and collaborative governance.Practical implicationsAs team integration is the central tenet of alliance projects, greater understanding regarding the leadership of integration practice is of value in leveraging the benefits of outstanding performance. Also, the results of the study are expected to be informative and provide insight for alliance teams to help them proactively recognise how the context of integrated teams is influenced by specific indicators, impacting on the extent of integration practice.Originality/valueThis study contributes to the current body of knowledge concerning the insights from the “lived experience” of alliance teams towards achieving a greater understanding of what contributes to the leadership of successful integration practices.

As often in project scheduling, when the project duration is shortened to reduce total cost, the total float is lost resulting in more critical or nearly critical activities. This, in turn, results in reducing the probability of completing the project on time and increases the risk of schedule delays. The objective of project management is to complete the scope of work on time, within budget in a safe fashion of risk to maximize overall project success. The purpose of this paper is to present an effective algorithm, named as adaptive multiple objective differential evolution (DE) for project scheduling with time, cost and risk trade-off (AMODE-TCR).Design/methodology/approachIn this paper, a multi-objective optimization model for project scheduling is developed using DE algorithm. The AMODE modifies a population-based search procedure by using adaptive mutation strategy to prevent the optimization process from becoming a purely random or a purely greedy search. An elite archiving scheme is adopted to store elite solutions and by aptly using members of the archive to direct further search.FindingsA numerical construction project case study demonstrates the ability of AMODE in generating non-dominated solutions to assist project managers to select an appropriate plan to optimize TCR problem, which is an operation that is typically difficult and time-consuming. Comparisons between the AMODE and currently widely used multiple objective algorithms verify the efficiency and effectiveness of the developed algorithm. The proposed model is expected to help project managers and decision makers in successfully completing the project on time and reduced risk by utilizing the available information and resources.Originality/valueThe paper presented a novel model that has three main contributions: First, this paper presents an effective and efficient adaptive multiple objective algorithms named as AMODE for producing optimized schedules considering time, cost and risk simultaneously. Second, the study introduces the effect of total float loss and resource control in order to enhance the schedule flexibility and reduce the risk of project delays. Third, the proposed model is capable of operating automatically without any human intervention.

The purpose of this paper is to propose a Non-Linear Integer Programming (NLIP) model that solves the resource leveling problem while reducing the negative effect of the total float loss on risk.Design/methodology/approachAn NLIP model is formulated to solve the resource leveling optimization problem incorporating float loss cost (FLC). The proposed model is implemented using “What’s Best solver” for Excel. The FLC is calculated using the float commodity approach. An example is solved using the proposed model in order to illustrate its applicability. Sensitivity analysis is also performed.FindingsThe results confirmed that resource leveling reduces the available float of non-critical activities; decreases schedule flexibility and reduces the probability of project completion. The probability of timely completion dropped from 50 percent (for the normal schedule with 32 resource fluctuations) to 13.5 percent for leveled resources with zero fluctuations. Using the proposed method, the number of resource fluctuations is 8 but the probability of completing the project on time improved to 20 percent.Practical implicationsThe proposed model allows project managers to exercise new trade-offs between resource leveling and schedule flexibility which will ultimately improve the chances of successful project delivery.Originality/valueResource leveling techniques result in reducing the available total float for the non-critical activities. Existing methods focus on moving noncritical activities within their available float and ignore the impact of the resulting float loss. This reduces the schedule flexibility and increase the risk of project delays. The proposed model incorporates the FLC into the resource leveling optimization problem resulting in more efficient schedules with improved resource utilization while keeping some schedule flexibility.

More attention should be paid to project managers’ (PMs) job satisfaction as they play an important role in ensuring projects are completed successfully. The purpose of this paper is to identify human resource management (HRM) policies and practices that lead to higher PMs’ job satisfaction.Design/methodology/approachA questionnaire survey was conducted on PMs who are working in construction firms and project management consultancy firms. Data were collected via random, convenience and snowball sampling. The data collected were analysed using partial least square-structural equation modelling, independent samples t-test and Pearson’s correlation.FindingsThe findings show that PMs who are satisfied with their firms’ HRM practices and job rewards also have higher job satisfaction. Several HRM strategies that give rise to higher job satisfaction are identified, e.g. a system to recognise and develop talent, and taking active steps to identify and develop backups in case of emergency. Unfortunately, some practices are not implemented to a significant extent, and these include: systematically recruiting and retaining talented PMs, encouraging PMs to plan for their careers, offering performance and development coaching, and appraising employees.Research limitations/implicationsThe limitations include the low response rate and the relatively small sample size of 81. The profile of respondents is largely from construction companies with more than 150 staff, and, therefore, the findings are more applicable to medium- to large-sized construction firms.Practical implicationsThe study identified many HRM practices and policies that are significantly associated with PMs’ job satisfaction, yet many of these are not implemented to a significant extent by the employers. The practical implication is that employers of PMs should systematically implement these in order that their PMs have higher job satisfaction which is important for a project’s success.Originality/valueThe originality of this research is that the HRM practices and policies that are associated with job satisfaction of PMs are uncovered. Its value is in showing that PMs derive greater job satisfaction when HRM policies encompass talent development, career coaching and a personalised management style. Among these important practices, those that have been neglected were also identified. The study offers recommendations on the HRM practices that firms should be put in place for their PMs to experience higher job satisfaction.

The purpose of this paper is to develop and explain an empirically validated scale to measure service quality for architects in India.Design/methodology/approachThis study applies a systematic procedure for development of a psychometric scale in three phases. Phase 1 includes item generation and selection through review of literature and expert opinion. Phase 2 comprises scale refinement using item analysis and exploratory factor analysis. Phase 3 applies confirmatory factor analysis (CFA) for establishing convergent, discriminant and nomological validity. This study has involved 15 expert participants in Phase 1 and sought participation from 250 respondents using an online questionnaire in two other independent phases.FindingsThe findings of the empirical study resulted in the development of a 22-item scale that measures the constructs such as design quality, project administration quality, communication quality, relationship quality and dependability quality.Research limitations/implicationsThis study has developed a context-specific psychometric scale of service quality for architects in India using snowball sampling. Although this study identified five valid service quality factors, the classified information relating to the formation of expectations was not collected.Practical implicationsThis reliable and valid scale would be helpful for architects to measure the level of service quality in enhancing business performance. This study has established that service quality for architects is achieved only when the perceived benefits are available from the aspects like design, project administration, communication, relationship and dependability.Social implicationsThis study can facilitate an architect interested in opportunities relating to contracting, consulting and engineering to explore possibilities of higher fees from clients.Originality/valueThis study is an original attempt in developing a validated tool to measure service quality of architects in India.
