Abstract
Purpose
This paper seeks to present research into the development of a theoretical model for making more informed decisions for the management of variations in building projects. Primarily, the study proposes six principles of effective variation management, which would be helpful for building professionals in assessing and taking proactive measures for reducing the adverse impact of variations.
Design/methodology/approach
Based on the principles of effective variation management, a theoretical framework for management of variation orders was developed. The stages presented in the theoretical framework were grouped into three main phases – screening, choice of promising alternatives, and dominance building. Based on the theoretical framework, a model for management of variations was developed.
Findings
The theoretical model presents a structured format for management of variation orders. The model will enable the project team to take advantage of beneficial variations when the opportunity arises without an inordinate fear of the negative impacts. By having a systematic way to manage variations, the efficiency of project work and the likelihood of project success should increase.
Originality/value
The study would assist building professionals in developing an effective variation management system. The model emphasized sharing the lessons learned from existing projects with project teams of future projects. The lessons learned should be identified throughout the project life cycle and communicated to current and future project participants. The system would be helpful for them to take proactive measures for reducing variation orders. Hence, the study is valuable for all professionals involved with building projects.

Abstract
Purpose
To provide an in‐depth analysis of the potential effects of variations in institutional building projects, which would be helpful for building professionals in assessing and taking proactive measures for reducing the adverse impact of variations.
Design/methodology/approach
To achieve the study objectives, a questionnaire survey was carried out to collect information on potential effects of variations. Responses from 28 professionals working for a developer organization (a government agency) were analyzed. Furthermore, 26 face‐to‐face interviews using the questionnaires were also analyzed.
Findings
The results suggest that the most frequent effects of variations were increase in project costs, additional payments for contractor, progress affected but without any delay, completion schedule delay, increase in overhead expenses and rework and demolition. Recommendations were suggested based on the findings of the research and literature review.
Research limitations/implications
This paper presented only the developers' view of the effects of variation orders on institutional building projects in Singapore. Further works can be extended to survey the consultants and the contractors who have carried out these projects.
Practical implications
The study will benefit the professionals involved with institutional building projects. The professionals would learn about the downstream effects that may assist in the valuable evaluation of variation orders.
Originality/value
This is a timely study as the program of rebuilding and improving existing institutional buildings is currently underway in Singapore. A clearer view of the effects of variations on the projects will enable the project team to take advantage of beneficial variations. Furthermore, the findings can be used by future researchers to carry out studies on the management of variation orders in various other types of projects.

Abstract
Purpose
The purpose of this paper is to explore the links between entrepreneurial behavior and success factors in a developing country context.
Design/methodology/approach
A case study approach was selected to analyze real‐life situations in order to gain an insight about entrepreneurial cognition and action related to success factors. Drawing from the behavioral theory of entrepreneurship, this paper presents a conceptual model which shows that entrepreneurial cognitions about success factors may lead toward entrepreneurial actions. The data were collected through face‐to‐face interviews. Three entrepreneurs were asked to outline responses to identified success factors such as start‐up planning, managing risk, learning, networking, managing human resource, and managing finances.
Findings
The results suggest that many behavioral patterns exhibited by the case study entrepreneurs were similar to entrepreneurs' behavior in more developed regions. The similarities include: preparation of business plan, ability cognition for start‐up planning, overconfidence and representativeness heuristics for managing risk, obtaining professional outsider assistance for learning, developing business relationships with suppliers for networking and favorable credit policies, and employing owner‐related and delaying‐payment methods of bootstrapping for managing finances.
Originality/value
For the first time in Pakistan this study explores entrepreneurial cognition and action in managing success factors. The findings of the research will potentially help practitioners and policy makers in nurturing entrepreneurial initiatives in a developing country context.

Abstract
Purpose
This study aims to examine how the just‐in‐time (JIT) principles can be adopted for the air travel industry with specific emphasis on the management and operations of terminal buildings in airports.
Design/methodology/approach
Three methods were adopted for the empirical part of this study. These included the observational walk‐through, interviews and survey questionnaires conducted in the Changi International Airport in Singapore. The evaluation for JIT application, as part of a larger study, includes the points of arrival and departure, the check‐in hall, immigration area, transit mall, gate lounges, food and beverage outlets, retail shops as well as other management initiatives that strive for continuous improvement. This paper focuses only on the check‐in hall.
Findings
Japanese businesses have been able to compete successfully in the world market in recent decades because of their total dedication to quality and productivity issues. This has been made possible in part by the guiding principles of the JIT concept which many Japanese businesses subscribed to. The JIT principles include waste elimination, pull production system, uninterrupted work flow, total quality control, top management commitment, employee involvement, long term working relationships with suppliers and continuous improvement. The JIT concept was specifically examined in this study in the context of the Changi International Airport through its planning processes and existing operations. The study was able to highlight the strengths as well as areas for potential improvements in the airport through the application of the seven JIT principles.
Practical implications
Beyond Japanese businesses, the JIT concept was also found to have benefited organizations in a wide range of industries including those relating to the built environment. The study covers major processes and procedures typical of the spatial management and operations of major airport terminal buildings which holds promising lessons for airport management worldwide.
Originality/value
The analysis shows significant potential in applying JIT principles for managing airport operations within the confines of the physical airport terminal buildings. It recommends that designers, project managers and asset managers should progress beyond the traditional “design follows functions” approach to adopt the more integrative “design follows JIT‐driven functions” approach.
