Title: Bridging the Digital Divide: A Critical Review of Information Systems Integration for Financial and Contractual Governance in Capital Projects Abstract: This study examines the systemic challenges and critical gaps in the adoption of information technology systems to support commercial and contractual governance within project-based engineering enterprises. Through a synthesis of existing literature and analysis of documented implementation failures—including near-corporate collapse following flawed software rollouts—the paper identifies a significant disconnect between available IT solutions and the complex, legally constrained processes of commercial project management. Key barriers include rigid contractual frameworks, inadequate change management strategies, and a lack of industry-wide standardization for core financial and administrative workflows. The analysis underscores the necessity for integrated systems that align with both engineering management's operational realities and commercial management's legal and fiduciary requirements. We propose a high-level requirements map for next-generation commercial systems and call for targeted research to develop interoperable, legally compliant digital tools that enhance financial control, risk mitigation, and value delivery across the project lifecycle. This work positions effective IT integration not as a support function, but as a foundational competency for modern engineering and commercial project leadership.
