Comprehensive Business Impact Analysis Report: Payroll System

This Business Impact Analysis (BIA) report details a contingency plan for a payroll system within a medium-sized company, focusing on system component prioritization and the impact of system unavailability. The analysis, completed on September 10th, 2019, identifies critical business processes such as employee data recording, attendance tracking, and salary calculations, correlating them to system resources like servers, software, and network infrastructure. It assesses outage impacts, including downtime estimations (MTD, RTO, and RPO), and outlines resource requirements for recovery. The BIA further establishes recovery priorities for system resources, providing a framework for building an Information System Contingency Plan (ISCP), Disaster Recovery Plan (DRP), and Cyber Incident Response Plan. The system architecture is described as a cloud-based SaaS with a hybrid cloud setup, integrating data from attendance and CRM systems. Detailed data collection includes process descriptions, outage impacts categorized by severity, and estimated downtimes, which inform the identification of resource requirements such as servers, software, and network components. The report concludes with a recovery priority list for system resources, including their Recovery Time Objectives, to ensure business process continuity.
