Which process is included in the computer safety lifecycle as per IEC-61508?

• A. System decommissioning
• B. Market analysis
• C. Public relations
• D. Vendor selection

Answer: (A)

The process included in the computer safety lifecycle as per IEC-61508 is focused on ensuring that safety concerns are addressed throughout the entire lifecycle of a system, from conception through to decommissioning. This standard emphasizes the need to consider safety implications at all stages, including design, implementation, and ultimately, decommissioning. When a system is decommissioned, it's essential to properly manage any risks associated with the removal or retirement of the system to ensure that safety is maintained even in the final stages of a system's life. This involves specific processes to safely terminate the operational capabilities and to handle any residual hazards in an appropriate manner. Other options, while related to business processes, are not primary considerations within the context of the computer safety lifecycle as defined by IEC-61508. Market analysis, public relations, and vendor selection focus more on business operations and supply chain management rather than directly addressing safety-critical design and operational standards that guide how technology is developed and retired in a safe manner.
