Requirements: Documenting, and validating the requirements of the system. Ensuring that the system will meet the needs of its users and stakeholders. Risk: Identifying and assessing potential risks that might affect the system's performance, schedule, or budget. This includes risk identification, analysis, mitigation, and monitoring throughout the project lifecycle. Functional: Examining the functions and capabilities of the system to ensure they align with the specified requirements. This may involve functional decomposition, use case analysis, or functional flow diagrams. Hazard and Operability, (HAZOP): A systematic approach to determine potential problems that can be exposed by reviewing the safety of designs and revisiting existing processes and operations in the depolyment, support and decommissioning of systems . Performance: Evaluating the system's performance against specified criteria, such as speed, throughput, reliability, and scalability. Performance analysis may include simulation, modeling, or testing under various conditions. Level of Repair, (LORA): To optimize repair decisions in order to minimize the overall life cycle costs of assets. The LORA process takes into account numerous factors, including: The costs of different types of repairs, including diagnostics, parts, and labor as well the impact asset failure could have on operations. Cost-Benefit: Assessing the costs associated with developing, operating, and maintaining the system against the expected benefits or value it will provide to stakeholders. This analysis helps in decision-making regarding resource allocation and trade-offs. Trade-off: Comparing different design options or alternatives to identify the most suitable solution based on various criteria, such as performance, cost, schedule, and risk. Stakeholder: Identifying stakeholders, understanding their concerns, priorities, and expectations, and analyzing how the system will impact them. This analysis helps in managing stakeholder relationships and ensuring their needs are addressed. Dependency: Identifying dependencies between system components, interfaces, or external factors to understand how changes or failures in one part of the system may affect others. Lifecycle: Assessing the system's lifecycle stages, including development, deployment, operation, and disposal, to ensure it meets lifecycle objectives such as sustainability, maintainability, and reliability. Sensitivity: Evaluating how changes in parameters or assumptions affect the system's performance, cost, or other characteristics. Sensitivity analysis helps in understanding the system's robustness and identifying critical factors. Reliability and Maintainability, (R&M): Directing system design in order to increase mission capability and availability and decrease logistics burden and cost over a system's life cycle. R&M Case: To collect evidence, assumptions and arguments employed in the specification, design, development and modification of a system in order to provide confidence in the system's level of reliability and maintainability.
