Timely identification of risks ( identifying a potential problem with sufficient lead time so that the team may implement appropriate alternate plans ) Consistent assessment of the level of risk across a program ( providing a structured decision making framework for prioritizing resource application ) Communication of risk mitigation actions across the program or organization ( ensuring that all elements of the program or organization are aligned in resolving risks ) Review of risk mitigation action performance Positive impacts on a plan or favorable consequences are not considered in this document in accordance with the FAA risk identification and analysis process guidance that treats them as opportunities ( Ref. 6 ). Rather q in the context of the SMS, safety is defined as freedom from unacceptable risk q ( Ref. 7 ). Types of Identified Risks 2.2 Various types of risks may be identified during the course of system development. As illustrated by Figure 2, high-level risks can be categorized as technical, schedule, and business or cost-related. Business Risks Schedule Risks Technical Risks Figure 2. - Types of potential risks. As explained in the NAS System Engineering Manual ( SEM ) ( Ref. 6 ): Many sources must be considered for each risk area. For technical risk, likely sources include technology maturity, complexity, dependency, stakeholder uncertainty, requirements uncertainty, and testing / verification failure. Sources of schedule risks may include incomplete identification of tasks, time-based schedule ( as opposed to event-based schedule ), critical-path scheduling anomalies, competitive optimism, unrealistic requirements, and material availability shortfalls. Cost risks may stem from an uncertain number of production units, supplier optimism, additional complexity, change in economic con...Original publisher: Cleveland, Ohio: National Aeronautics and Space Administration, Glenn Research Center,  OCLC Number: (OCoLC)747707356 Excerpt: .
