The purpose of this study is to extract the real requirements of the owner (or users) for the construction project in the operation and maintenance stage completely and accurately and carry out the construction based on the requirements, to make the project status and operation and maintenance requirements (RO&M) consistent after delivered.

This study creatively proposes the operation and maintenance functions deployment (OMFD) under RO&M. In addition, the OPAR (naming is made up of the initials of owners, project, analysis and result) model is constructed to fully identify the requirements of both owners and projects. In this study, three typical construction projects are taken as examples to calculate the correlation strength between project characteristics (PC) and operation and maintenance requirements through the Apriori algorithm, and order parameters are obtained from the cost chain.

This study found that there are significant differences in the correlation strength between 11 types of RO&M and PC, in which the “cost of types” (TC) correlation of residential housing and factory buildings is the largest, while the largest correlation demand of commercial buildings is “safety of types” (TS) and “system” (S). Simultaneously, through the calculation of order parameters, the most influential factors on project characteristics are obtained.

This study could effectively help the owner (or users) to check whether the delivered project fully satisfy their real requirements and also extract the key technical points to realize RO&M, which can guide the accurate construction of the same type of projects.

This research establishes OPAR model to accurately identify the requirements of the project in the operation and maintenance stage and establishes the association rules between the requirements and the construction scheme, which is helpful for the project to construct under the expected requirements.

This paper aims to focus on requirements management of projects constructed under traditional procurement system. It seeks to discuss the requirements management processes highlighting the limitations and addressing the need for a practical framework for facilitating the implementation of requirements management in the construction industry.

Two research instruments were used in this paper: semi‐structured interviews and case studies.

The literature review introduced a generic process for requirements management practice potentially to be adopted in the construction industry. The research study identified that the processes and limitations of current practice included the lack of a practical framework, misinterpretation of requirements, difficulties in identifying requirements, conflicts between expectation and constraints, complex hierarchy of client's organisation and communication problems in eliciting client requirements. Recommendations are given that an inclusive project brief and a competent project manager to manage the project requirements are necessary in capturing and tracing the requirements during the project development process. A practical framework is needed to improve the requirements management practice within the construction industry.

The research findings establish the basis for further research to examine the implementation of these potential solutions and development of a systematic framework for RsM. The research is of significant value to the construction industry where value generation is essential and critical, especially in difficult economic and financial situations.

Requirements are the foundation of the projects which are critical to the successful delivery of the projects. Although many guidelines have been published for managing client requirements, the existing practice on requirements management is still considered to be inadequate. This research provides insight for professional practitioners in the construction industry to improve the requirements management practices for development projects.

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

Taking a co-creation perspective and integrating knowledge-based and resource-based perspectives, the authors examine the role of customer participation in organizational performance and project success. The authors also investigate the mediating role of knowledge integration and the moderating role of requirement risk for these relationships in uncertain contexts.

The authors undertook two studies. The first study was carried out in 2018 in which the authors drew on survey data from 150 information technology (IT) sector employees and examined the mediating role of knowledge integration in the relationship of customer participation with organizational performance and project success. In the second study undertaken in 2020, the authors drew on data from 92 IT and telecom sector employees and examined the moderating role of requirement risk in the relationship between customer participation and knowledge integration. Study 2 was conducted during the COVID-19 pandemic when employees were largely working from home and were more sensitive to risks and uncertainty about the scope and system requirements. Both studies were survey-based, and analysis was carried out using structural equation modeling.

The authors’ two-study examination indicated that knowledge integration positively mediates the relationship of customer participation with organizational performance and project success during the co-creation process. Furthermore, the authors demonstrate that when requirement risks are high, customer participation relationship with knowledge integration is weaker.

The authors show that integrating customer knowledge is critical to project success and organizational performance. By identifying risk uncertainties and environmental contingencies, the authors highlight the constraints of customer participation for knowledge integration, organizational performance and project success. The authors provide some key study findings based on survey data obtained from project teams during two periods (normal and pandemic).

The purpose of this paper is to explore the contribution of the design quality indicator (DQI) tool in the management of client requirements in construction projects, and propose a requirements-oriented project process (ROPP) to ensure continued focus on client requirements throughout the lifecycle of a project.

Direct participant involvement and case studies of building projects that have used the DQI tool are used to analyse the extent to which DQI contributes to the management of client requirements.

Case study analysis suggests that the DQI enhances focus on client and project stakeholder requirements through the initial quality aspirations set out at the beginning of a project, but it is limited in its scope to address a more comprehensive requirements profile.

The proposed ROPP model is conceptual and requires further development to test its effectiveness in enhancing focus on client requirements. However, given current developments in automated checking in BIM and other environments, this offers scope for further research in this area.

Maintaining focus on client requirements throughout the process is a key criterion for project success. However, given the many stakeholders involved, and the progressive translation into various project documents, there is a risk that focus on the original/evolving requirements of the client can be lost. Current approaches such as the DQI have limitations and a robust ROPP is, therefore, a key contribution to securing clients’ objectives over the project lifecycle.

The systematic assessment of working capital requirement in construction projects deals with the analysis of various quantitative and qualitative factors in which information is subjective and based on uncertainty. There exists an inherent difficulty in the classical approach to evaluate the impact of qualitative factors for the assessment of working capital requirement. This paper presents a methodology to incorporate linguistic variables into workable mathematical propositions for the assessment of working capital using fuzzy set theory. This article takes into consideration the uncertainty associated with many of the project resource variables and these are reflected satisfactorily in the working capital computations. A case study illustrates the application of the fuzzy set approach. The results of the case study demonstrate the superiority of the fuzzy set approach to classical methods in the assessment of realistic working capital requirements for construction projects.

The purpose of this paper is to explore existing problems and potential solutions of managing Employers' Requirements in the project development process of construction projects under traditional procurement systems.

Two research instruments are used: semi‐structured interview and questionnaire survey, to investigate the problems and potential solutions to Requirements Management in the construction industry.

The research revealed that Requirements Management is crucial to the successful delivery of construction projects. However, the current practice of Requirements Management in the industry is informal and there is a lack of a systematic approach to tackle the problems. The authors also propose potential solutions to Requirements Management as well as a vision for further research.

The paper presents the problems of managing Employers' Requirements, and the potential solutions to improve the Requirements Management process that need to be addressed.

The paper improves one's comprehension of the nature, characteristics, problems and potential solutions of Requirements Management in the project development process under the traditional procurement systems in the construction industry, relevant to both practitioners and scholars. A model is proposed as a “preliminary framework” to show the processes involved.

The purpose of this paper is to describe and analyze the role of requirement managers in new product development projects.

This paper is based on a case study of an industrial platform project. Sixty-eight persons were interviewed and project prerequisites and requirement specifications documents were studied. The roles of specific individuals and their formal role as requirement managers are reported.

The requirement manager's role fulfillment is performed through five major activities described as developing, anchoring, re-organizing, routinizing, and positioning. These activities are essential in order to manage working with a large flagship project.

Because the research was based on a single case study, there are of course limitations. The findings in this study may therefore not be generalized, but merely suggest other areas of research.

This paper argues that functional roles should not be taken for granted. Even though significant efforts may have been performed in order to establish a new role within a project management setting, the process of establishing new work practices is complex. Managers should therefore investigate inter-functional integration on ongoing bases.

This paper provides important insights into aspects of requirement manager's ongoing project activities.

This paper aims to investigate the prevailing practice of managing client requirements for design and build (D&B) construction projects in Hong Kong. It attempts to evaluate the limitations and addresses the need for a practical framework for facilitating the implementation of client requirements management within the industry.

Two research instruments were used in this paper: semi‐structured interviews and case studies.

The study revealed that the limitations of the current practice included the lack of a comprehensive client's project brief, inadequate involvement of client in the briefing process, the lack of impartial agents, the controversy caused by the uncertain legal status of end‐users and the improper timing of raising requirements by key project stakeholders. Recommendations are given that an inclusive project brief is necessary in clarifying the goals and covering all‐rounded perspectives. A practical framework is needed to improve the client requirements management practice within the construction industry.

The D&B procurement system adopted in Hong Kong actually exists in various forms within the construction industry, which differ from the prototype that has long been recognized. Therefore, a more detailed study into D&B projects covering a broader area is necessary in the future.

Little research work has been undertaken on the study of client requirements management, especially for D&B construction projects. This paper has improved the comprehension of the nature of client requirements and has provided valuable insights into the prevailing problems associated with the management of client requirements.

There are differing views and results in the literature regarding whether the user’s participation has a positive or negative impact, if any, on the success of an information system (IS) project. The purpose of this paper is to develop a comprehensive model with four main hypotheses to test the relationships between seven constructs using survey data conducted in the USA.

The authors develop a structural equation model (SEM) with four constructs defining the activities the user participates in and three constructs defining user satisfaction as a measure of project success. As such, the proposed SEM is the most comprehensive among the models offered in the literature to date, and includes, for the first time, a presentation requirement construct as a specific system requirement for possible user participation.

The authors find that a business user’s participation in functional requirements benefits project outcome, whereas business users should not participate in gathering presentation requirements unless they are experienced middle managers.

This study surveyed many industries across the USA and provided a solid statistical base for analysis. Future research should consider exploring IS projects in other countries since various cultures can differ in how they approach to such projects. Additionally, industries are known to have dissimilar needs; therefore, a study exploring specific industries would add to the available research.

The authors find that when the general business user participates in certain activities that relate to presentation of the system, his/her involvement negatively impacts the project success. However, if that business user is a middle manager, he/she has a positive impact on the project success. Similarly, when the business user participates in managing the projects, that involvement negatively impacts the project outcome (although the amount of negative impact is relatively small). These results should have an influence on the way the IS project managers allocate business resources to activities, and their decisions regarding whether and where the business users participate.

The authors expect higher levels of business user satisfaction on IS projects if they are allocated to a limited subset of project activities that has a positive impact on project outcomes.

The authors believe these findings contribute to this research domain considerably since they are based on a large sample size on a new comprehensive model of business users that can be generalized across industries. The separation of business requirements into functional and presentation requirements has suggested that there are differing impacts to the project depending on the type of business user involved.
