For an agreement to be considered good, it must be agreeable to both parties and also be what?

A good agreement should indeed be agreeable to both parties involved, and it also needs to be in the public interest. This means that beyond just satisfying the immediate needs or desires of the parties, the agreement should contribute positively to the broader community or society. When an agreement serves the public interest, it enhances ethical standards and may promote goodwill, accountability, and sustainability among involved parties.

The importance of being in the public interest is particularly pronounced in scenarios where the agreement impacts external stakeholders or the community. For instance, contracts related to public services, resources, or environmental issues necessitate a consideration of the wider implications. This ensures that the arrangement not only serves the interests of the parties but also adheres to larger societal values and norms, fostering trust and cooperation.

The other options do not align with the principle of a good agreement. An agreement that is only beneficial to one party would inherently be unbalanced and could lead to conflict or dissatisfaction. While budget effectiveness and the speed of implementation might be practical considerations, they do not address the fundamental ethical and communal aspects that define a truly good agreement.
