Under ISO 9001 principles, top management is accountable for the effectiveness of the quality management system. Executive management must establish quality policy, align quality objectives with organizational direction, provide resources, promote process thinking, support risk-based thinking, and ensure that the quality management system achieves intended results. A quality director may manage quality activities, audits, procedures, and reporting, but responsibility cannot be fully delegated away from executive leadership. A project manager is responsible for project execution, not the entire organizational quality management system. Software quality engineering supports compliance, measurement, verification, and improvement, but does not own ultimate accountability. Therefore, executive management is responsible for ensuring the quality management system is effective.

Software cost estimation models, such as COCOMO (Constructive Cost Model), commonly use " Lines of Code (LOC) " as a primary input. LOC is a measure of the size of a software program by counting the number of lines in the source code. This metric is essential for estimating the amount of effort and time required to develop the software. Other inputs may include function points and other metrics, but LOC remains a fundamental component in many models. References: Barry W. Boehm ' s " Software Engineering Economics " .

For safety-critical software, it is crucial to specify how the system should react to accidents or hazardous conditions to mitigate risks and ensure safety. This type of requirement directly addresses safety concerns by defining specific actions that the system must take in response to potential safety issues.

Performing verification and validation on safety-critical features involves several key activities aimed at ensuring that software functions correctly and safely throughout its lifecycle. One critical activity is performing software hazard analysis and determining acceptable levels of safety risks. This process involves identifying potential hazards that the software could pose and evaluating the risks associated with these hazards. By assessing these risks, teams can establish acceptable safety levels and implement measures to mitigate or eliminate these risks. This activity is fundamental in ensuring that the software meets safety requirements and standards, such as those outlined in safety-critical industry guidelines like ISO 26262 for automotive or DO-178C for aerospace.
