Final answer:
The question is addressing how an organization must consider various requirements and constraints, health and safety guidelines, and public acceptance when deciding the acceptable level for a system after determining all pertinent factors.
Step-by-step explanation:
After an organization determines all pertinent requirements and constraints to a system, it must decide its acceptable level. This involves considering various factors such as health and safety guidelines, environmental impact, and public acceptance.
Factors like primary standards, which are limits based on human health, and secondary standards, which aim to prevent environmental and property damage, are critical for setting permissible levels. Additionally, organizations may need to determine the level of Bio-Safety Level (BSL) necessary for working with specific pathogens, and evaluate whether system prototypes meet design and performance constraints.
