Purpose As a result of the increasing challenges of time overrun, several companies regularly set up delay assessment procedures for performance improvement and profit maximization. In the construction industry, projects are enormously complicated and involve significant budgets, and therefore optimizing project performance through the root cause analysis should be imperative for every project manager. Typically issues of delays in projects are generally discussed and problematized separately, yet a comprehensive framework for systematic analysis and grouping of delays is rarely contended. The purpose of this paper is to introduce the 4P concept (project related, practices, participants, and procurement) for identifying, analyzing, and classifying delays in the internal environment of the project development process. Design/methodology/approach The 4P conceptual framework was validated through the synthesis of the existing literature. Findings Interestingly, despite the increasing concerns about delays in the construction industry, most research on delays are project and/or country specific, thus no consensus about the sources of delays. The application of the proposed concept as a theoretical framework would provide an understanding of the available delay sources, their risks and use for project delay assessment and classification. Research limitations/implications This study grouped delays based on the shared characteristics and four main sources were identified and analyzed. There may be other sources or factors, yet would be dependent or aspect of the 4P. Practical implications The study informs project teams to reduce delays in the construction industry. Originality/value The paper is an application of risk assessment tool to conceptualize delays in the internal project environment.

The focus of this paper is to present a discussion of the role of the private sector in response to the need for climate change adaptations. The study, which was conducted through a literature review, investigates the concept of the green economy and climate change, as well as businesses’ commitment to advance climate actions in ways that build resilience in vulnerable communities in developing countries. The paper calls on companies with national, regional, and/or global reach to adopt or develop strategies that improve resource efficiency, reduce greenhouse gas emissions, and reduce the loss of biodiversity. Businesses can accelerate this transition by aligning their investments with climate change adaptation opportunities, and thus, “green” the economy. In addition, green growth could be achieved through tactical public and private investments in mitigating climate change. The paper concludes that the private sector is a key sector in addressing the challenges of vulnerable communities, and it has much to contribute to the planning, development, and implementation of climate adaptation strategies, including sector‐specific expertise, technology, efficiency, financing, and entrepreneurship. Finally, some social conditions and environmental boundaries have been highlighted in this paper to attract the attention of business leaders who are trying to build initiatives and advance climate actions that will reduce socio‐community risks from climate change. Also, comprehensive initiatives and strategies have been recommended to private companies seeking to address climate vulnerabilities.
