Which type of risk necessitates risk treatment according to established guidelines?

The selection of high and medium risks as the type that necessitates risk treatment according to established guidelines aligns with the principles of risk management in systems engineering. High and medium risks are considered critical because they possess the potential to significantly impact project objectives, whether in terms of cost, schedule, performance, or safety.

Established guidelines typically recommend that any identified risks that fall into high or medium categories be actively managed to mitigate their potential negative effects. This may involve implementing specific strategies for avoidance, transfer, reduction, or acceptance of risks. The rationale behind this guideline is to prioritize resources and attention toward those risks that could derail project success, thereby safeguarding the overall integrity and viability of the system being developed.

On the other hand, low, negligible, and insignificant risks generally do not require extensive treatment due to their minimal impact on project objectives. These risks can often be monitored and accepted without active intervention, allowing teams to focus their risk management efforts on those threats that more significantly jeopardize project outcomes.
