I am trying to learn more about a particular piece of software used to submit forms to a US federal agency. I have a 'procurement document number' sometimes also called an 'award ID'. Using this number I can locate a minimal amount of information about the contract at FPDS.gov and usaspending.gov. This information shows that the contract is an open-bid, only received one bid, the name of the bidder/contractor, and payments made. I want to learn more about the details of the RFP, the bids, and any deliverables.
My goal is to learn the details of a procurement. The software in question is horrendously bad, developed in 2014 with something that would be unacceptable in 1995. Constant delays, outages, and obvious inefficiencies.
How can I jump from the procurement number to more detailed information?
Is this readily available or must I make a FOIA demand?
I am intentionally not including the number. I want to learn how to jump from any number to more meaningful information in general. That generic skill will get me the info I want for this task as well as other tasks.
