Final answer:
Sheng's supervisor should carefully evaluate Sheng's proposal, involve relevant stakeholders in the decision-making process, and provide constructive feedback and transparent communication.
Step-by-step explanation:
In this situation, the ethical action that Sheng's supervisor should take is to carefully consider and evaluate Sheng's proposal. The supervisor should actively listen to Sheng, ask for more information if needed, and consider the potential benefits and risks of implementing the innovative supply management program.
In doing so, the supervisor should provide constructive feedback to Sheng, acknowledging the value of his idea and expressing appreciation for his initiative. The supervisor should also involve other relevant stakeholders, such as higher management or colleagues with expertise in supply management, to collectively assess the feasibility and potential impact of the proposed program.
It is important for the supervisor to maintain transparency and provide clear communication regarding their decision-making process and any limitations or challenges that may prevent the immediate implementation of the program. Respecting Sheng's contribution and actively involving him in the decision-making process can also foster a positive work environment and encourage future innovation and collaboration.
