Better Predictions, Better Outcomes: How Integrated Cost & Schedule Risk Analysis (iCSRA) Reduces Costly Consequences of Project Delays

Abstract The success of major capital projects hinges on the balance between revenue and expenditure. Integrated Cost & Schedule Risk Analysis (iCSRA) emerges as a critical tool for enhancing predictability and mitigating risks associated with project delays and cost overruns. This paper explores the impact of iCSRA on project outcomes, drawing on actual performance data openly published by the Norwegian Offshore Directorate and other industry benchmarks. Key findings reveal that a significant proportion of projects exceed budget and schedule estimates at Final Investment Decision (FID), with only one in seven (14%) experiencing cost and schedule underruns. iCSRA helps address these challenges by providing a probabilistic approach to risk management, enabling better alignment of project teams and more informed decision-making. The methodology involves detailed risk identification, probabilistic modelling, and collaborative workshops to refine project schedules and cost estimates. The paper underscores the importance of robust data inputs and the need to account for biases and uncertainties in risk assessments. By integrating cost and schedule risks, iCSRA offers a comprehensive view of project uncertainties, facilitating more accurate predictions and effective risk mitigation strategies. The ultimate goal is to maximize project success by improving the confidence level in achieving both cost and schedule targets, thereby enhancing the overall value and credibility of projects.
