Requirements Definition and Management Practice to Improve Project Outcomes

Abstract Poor project requirements definition and management (RDM) is one of the major causes of project failure. However, many organizations do not adequately manage a projects requirements leading to a poor design basis. Thus, quality of requirements is critical to the success of any construction project. The primary purpose of this research was to investigate the mediating effect of requirements quality on the relationship between RDM practice and project performance. The second objective was to determine whether the impact of RDM practice on project performance was moderated by project characteristics. A three-phase approach was employed to investigate construction projects in the Taiwanese building industry. The testing supports a role for requirements quality as a partial mediator in the relationship between RDM practice and project performance. The findings also indicate that project characteristics have a moderating effect on the relationship between requirements quality and overall project perfo...

Information platform to improve technological innovation capabilities: role of cloud platform

AbstractConceptualizing technological innovation capabilities and cloud platform implementation in the construction management context is still rudimentary. The primary objective of this study was to validate a model for assessing the relationships among information platform usage, technological innovation capabilities, and capital facility project performance. This study also evaluated the moderating role of type of platform in the relationships. This study empirically investigated a sample of projects in the Taiwanese construction industry. The structural equation modeling (SEM) approach was used to validate the research model. In testing the moderation effect, two-way analysis of variance (ANOVA) was used. The findings indicate that implementation of information platform contrubutes significantly to technological innovation capabilities. In addition, these analyses suggest that technological innovation capabilities have a positive effect on project performance. The results also show that the relationsh...

A comprehensive framework for evaluating key project requirements

AbstractRequirements definition affects work performed in subsequent phases of a project. Thus, the compliance with requirements is crucial to the success of a project. The primary objective of this research was to develop a comprehensive framework for evaluating key building project requirements. The second objective was to identify and prioritize important project requirement using the analytical network process (ANP). The third objective was to examine the impact of requirement completeness on project success using structural equation model (SEM) analysis. A four-phase approach was employed to achieve the goals. The results suggest that building programming and site information have a higher priority in requirement definition than project control, project strategy, and project design parameter. The findings also indicate that requirement completeness may contribute significantly to building project success in terms of schedule success, cost success, quality performance, and overall benefit.

Applying value engineering to evaluate the use of concrete in an underground railway construction project

The object of this research is an underground railway construction project. The railway will be 8.23 kilometers long with three stations located along it. The project will cost totally NT

The current practice and promotion strategy of dry-mix mortars in Taiwan — Taking technology acceptance model as an approach

29.36 billion and take seven years and eight month to complete. The total amount of concrete used in this project is estimated to be as large as 56,900 cubic meters. By using the value engineering technology, this study evaluated totally five concrete alternatives for the construction project. According to the findings of this research, self-compacting concrete (SCC) is the best alternative for it can help to save nearly NT

The association among project manager's leadership style, teamwork and project success

A study on the relationship between intellectual capital and business performance in the engineering consulting industry: A path analysis

352 million for concrete. The amount of cement required for the project is half the amount of regular concrete project. In addition to cutting costs, SCC is more environmentally friendly for it uses industrial wastes as its ingredients. It is known as the green concrete for it is helpful in reducing carbon emissions and, hence, mitigating the greenhouse effects. The findings and suggestions of this study were sent to the authorities in charge of the project and have been accepted and adopted by the engineering consultants in the underground railway construction.

Knowledge leadership to improve project and organizational performance

Compared with traditional cement processing methods, dry-mix mortars are more environmental friendly by reducing air pollution or waste production on construction sites. It can also reduce carbon dioxide emissions, helps to keep the construction site clean, and allow for more flexibility in storage space for materials while reducing cement redundancy after the cement finishing is completed. It can be said that this new and advanced construction material is environmental friendly and convenient to deploy and transport, delivers product of stable quality, helps to facilitate construction, and saves materials. In this study, a questionnaire survey was conducted on people in the construction industry in Taiwan to explore their perceptions of the characteristics of dry mix mortars and their acceptance of this material. Totally 133 valid samples were returned. After the analysis of the questionnaire results, this research found the more the respondents find dry-mix mortars useful, the more satisfied they are with the material; the more they are satisfied, the more willing they are to promote it. Among all the factors, the perceived usefulness of this material has a particularly significant influence.
