System Assurance is the process a project shall adhere to ensure that its goals are delivered safely and reliably as well as meet its objectives. This involve assuring the products and the systems used as well as assuring the process followed in the system development.
System Assurance (SysA) is the planned and systematic set of engineering activities necessary to assure that products conform with all applicable system requirements for safety, security, reliability, availability, maintainability, standards, procedures, and regulations, to provide the user with acceptable confidence that the system behaves as intended in the expected operational context.
Generally issues are found in the assurance stages,thus the details of the system Assurance is required to be provided at product level up to the system levels. We at Intellex can undertake safety assurance from product safety assurance to system safety assurance by complying to EN61508 & EN50126/8/9 standards.
- Product Assurance – Assuring the products used in the project has been developed in accordance with applicable standards(EN61508), proven legacy of maturity of application
- Subsystem Assurance – For larger projects, system is divided into subsystems functionally. Each subsystem requires a degree of Assurance deepening on its safety criticality in accordance with CSM,EN50126/8/9.
- System Assurance – System Assurance is about assuring the change introduced to the railway is integrated properly and any risk arising from interface hazards has been mitigated to ALARP in accordance with CSM,EN50126/8/9.
