Answer :
The appropriate measurable 'shall' requirement is 'The system shall be capable of deterring wildlife and pests from harming crops and stealing food.' It necessitates clear, unambiguous language for proper implementation and verification, considering the complexities of ecological pest management. So the correct answer is option (c)
The correct rewording of the requirement into a good measurable 'shall' requirement is: The system shall be capable of deterring wildlife and pests from harming crops and stealing food. This phrasing most closely adheres to standard requirements language used in systems engineering and project specifications, where 'shall' indicates a mandatory requirement. Converting this into a measurable criterion would involve defining how 'deterrence' is measured, the types of wildlife and pests to be addressed, and under what conditions the system must operate effectively. The language must be clear and unambiguous to allow for proper system implementation and subsequent verification.
In the context of pest management, traditional approaches often involve the use of pesticides, which, while effective in the short term, can lead to a host of long-term problems such as resistance building in pest populations, collateral damage to non-target species, and potential harm to human health and surrounding ecosystems. The provided information highlights the importance of adopting strategies that support ecological balance and sustainability—such as increasing landscape complexity to bolster natural pest-suppressing organisms or turning to biological control methods, which introduce predators or parasites to control pest populations. Emphasizing systems thinking, it is essential for pest management solutions to consider the complex interactions within agricultural ecosystems and the potential unintended consequences of interventions. So the correct answer is option (c)
