Preliminary risk analysis (PHA), hazard and operability study (HAZOP), and failure mode and effects analysis (FMEA/FMECA) are systematic risk assessment techniques widely used in Business Continuity Planning (BCP), Disaster Recovery (DR) planning, and audit processes to identify vulnerabilities, anticipate disruptions, and enhance organizational resilience. These methods provide structured approaches to understanding potential threats to systems, operations, and infrastructure, enabling organizations to prioritize controls and maintain continuity during adverse events. In the context of BCP and DR, risk identification is the first and most crucial step, and these analytical techniques contribute to building robust recovery strategies and minimizing operational downtime. Preliminary risk analysis (PHA) is an early-stage risk assessment method applied during the initial phases of system design, project development, or organizational planning. Its primary objective is to identify potential hazards, assess associated risks, and determine whether further detailed analysis is necessary. Within BCP and DR planning, PHA helps organizations recognize critical threats such as cyberattacks, natural disasters, supply chain disruptions, or infrastructure failures before systems are fully operational. The process involves defining system boundaries, identifying assets, listing potential hazards, evaluating the likelihood and consequences of each risk, and recommending preliminary control measures. PHA is generally qualitative or semi-quantitative and relies on expert judgment and historical data. Its strength lies in early detection, allowing organizations to integrate risk mitigation strategies into their continuity frameworks from the beginning. In audits, PHA results provide documentation demonstrating that management has proactively considered risks and implemented preventive controls aligned with continuity objectives. Although PHA does not offer the detailed analysis of
