Final answer:
Organizations can request more detailed proposals, conduct reference checks, seek additional information, and host bidder presentations to make better-informed decisions between contractors.
Step-by-step explanation:
If an organization is having trouble deciding between contractors after narrowing down the list of proposals, several steps can help in making a final decision. First, the organization could request more detailed proposals to get a deeper understanding of what each contractor offers. Additionally, conducting reference checks on the contractors can provide insights into their past performance and reliability.
Seeking additional information or clarification can also be useful when there are specific aspects of the proposals that are unclear or need elaboration. Finally, bidder presentations can allow contractors to articulate the value of their proposal and to address any concerns the organization might have directly.
These methods allow the organization to gather more evidence and interact directly with the potential service providers, leading to a more informed and confident decision.
